A few more tools that I've found useful for console-only Linux server administration. All of these have Gentoo ebuilds so they can simply be emerge'd into your system.

atop - Similar to the built-in "top" command in Linux/Unix, except that it gives additional details about what is going on with the system. Of particular use is that it will show you individual disk utilization statistics so that you can locate spindles that are in heavy use. (Which is much needed when tuning a database server.)

tree - Allows you to output a hierachial display of all files and directories on your system in a "tree" view. Which is useful for documenting the directory layout of your system.

I'm not going to get into the full details of configuring a time server for your Windows 2000 or Windows 2003 domains, but the basic idea is that your PDC (Primary Domain Controller) at the root of your Active Directory forest should be synchronized with an external time source. Microsoft includes a service to do this called "Windows Time" (a.k.a. W32Time). It's not as nice as the official NTPD service that you can get from ntp.org, but it generally works.

By default, Windows client computers that are members of a domain should get their time from the domain controllers within the domain. So once you get the domain controllers keeping time properly you won't have to deal with bad time on the desktops.

Microsoft Articles:
Registry entries for the W32Time service
Basic Operation of the Windows Time Service

An extremely good page that shows you whether W32Time is configured properly to sync against an external server. The basic idea is that you stop the "Windows Time" service and the execute the following command at the prompt.

w32tm -once

The key line in the above output is "Error -45702ms" which shows us how much the Windows server's clock is going to be adjusted by. You should also look in your System Log (filter for W32Time events) for messages after using the above command (or after stopping/starting the time service). Those messages in the system log will help you determine why you may not be able to synchronize to an external time server (via 123/udp).

In my opinion, W32Time is "good enough" for most purposes. At least for small offices or home networks. If you're going to be dealing with more then a dozen servers or 50 workstations, then you should definitely look into setting up a real "ntpd" server. (In reality, you should have at least 4 ntpd servers in your infrastructure so that they can keep an eye on each other and alert you to ntpd servers that are not keeping time properly.)

Extending a Logical Volume

The basic (3) commands are:

lvextend
e2fsck
resize2fs

For example, I have /home that is currently a 4GB partition mounted in my vgmirror volume group. In order to turn /home into a 64GB partition, I need to use the following commands.

# pvscan
# lvscan
# umount /home
(if you can't unmount the volume, you may need to boot the LiveCD)
# lvextend -L+60G /dev/vgmirror/home
# e2fsck -f /dev/vgmirror/home
# resize2fs /dev/vgmirror/home
# mount /home

Now, for /home, odds are high that you will have to boot a LiveCD due to the volume being in use.

Working on setting up lm_sensors on my Gigabyte GA-6VA7+ (Intel Celeron Coppermine 566Mhz CPU) system. First step is to turn on I2C support in the 2.6 kernel configuration.

# cd /usr/src/linux
# make menuconfig

Device drivers
--> I2C Support
--> --> I2C Support (turn ON as BUILT-IN)
--> --> --> I2C device interface
--> --> --> --> (turn all sub-options on as MODULE)
--> --> --> I2C Algorithms
--> --> --> --> (turn all sub-options on as MODULE)
--> --> --> I2C Hardware Bus support
--> --> --> --> (turn all sub-options on as MODULE)
--> --> Miscellaneous I2C Chip support
--> --> --> (turn all sub-options on as MODULE)
--> --> I2C Core debugging messages (turn ON as BUILT-IN)
--> --> I2C Algorithm debugging messages (turn ON as BUILT-IN)
--> --> I2C Bus debugging messages (turn ON as BUILT-IN)
--> --> I2C Chip debugging messages (turn ON as BUILT-IN)

Now, make sure that /boot is mounted, then compile your new kernel.

# make && make modules_install
# mount /boot
# cp arch/i386/boot/bzImage /boot/kernel-2.6.13-28Nov2005-2037
# cp System.map /boot/System.map-2.6.13-28Nov2005-2037
# cp .config /boot/config-2.6.13-28Nov2005-2037
# nano -w /boot/grub/grub.conf

Now, this is just a testing configuration and not my final configuration. After the boot, I'll have to figure out what sensors are actually available and which ones I need to keep.

# emerge -pv lm_sensors
# emerge lm_sensors

While that's compiling, read the lm_sensors FAQ. Section 3.1 (Why so many modules, and how do I cope with them?) explains the basics of how to get started with lm_sensors.

(Notice the warnings at the end of the ebuild.)

>>> /etc/init.d/lm_sensors

* Next you need to run:
* /usr/sbin/sensors-detect

# /usr/sbin/sensors-detect

The following is output from my Gigabyte motherboard:

# sensors-detect revision 1.393 (2005/08/30 18:51:18)

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters...
Use driver `i2c-matroxfb' for device 01:00.0: MGA G200 AGP
Use driver `i2c-viapro' for device 00:07.3: VIA Technologies VT82C596 Apollo ACPI
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Load `i2c-matroxfb' (say NO if built into your kernel)? (YES/no): yes
FATAL: Module i2c_matroxfb not found.
Loading failed... skipping.
Load `i2c-viapro' (say NO if built into your kernel)? (YES/no): yes
Module loaded succesfully.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no): yes
Module loaded succesfully.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).

Next adapter: SMBus Via Pro adapter at 5000
Do you want to scan it? (YES/no/selectively): yes
Client found at address 0x50
Probing for `SPD EEPROM'... Success!
(confidence 8, driver `eeprom')
Probing for `DDC monitor'... Failed!
Probing for `Maxim MAX6900'... Failed!
Client found at address 0x51
Probing for `SPD EEPROM'... Success!
(confidence 8, driver `eeprom')
Client found at address 0x52
Probing for `SPD EEPROM'... Success!
(confidence 8, driver `eeprom')
Client found at address 0x69

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no): yes
Probing for `National Semiconductor LM78'
Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'
Trying address 0x0290... Failed!
Probing for `National Semiconductor LM79'

Trying address 0x0290... Failed!
Probing for `IPMI BMC KCS'
Trying address 0x0ca0... Failed!
Probing for `IPMI BMC SMIC'
Trying address 0x0ca8... Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan for Super I/O sensors? (YES/no): yes
Probing for `ITE 8702F Super IO Sensors'
Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
Failed! (skipping family)
Probing for `Winbond W83627EHF/EHG Super IO Sensors'
Failed! (skipping family)

Do you want to scan for secondary Super I/O sensors? (YES/no): yes
Probing for `ITE 8702F Super IO Sensors'
Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
Failed! (skipping family)
Probing for `Winbond W83627EHF/EHG Super IO Sensors'
Failed! (skipping family)

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `eeprom' (should be inserted):
Detects correctly:
* Bus `SMBus Via Pro adapter at 5000'
Busdriver `i2c-viapro', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus Via Pro adapter at 5000'
Busdriver `i2c-viapro', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus Via Pro adapter at 5000'
Busdriver `i2c-viapro', I2C address 0x52
Chip `SPD EEPROM' (confidence: 8)


I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)? isa

If you want to load the modules at startup, generate a config file
below and make sure lm_sensors gets started; e.g
$ rc-update add lm_sensors default.

To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----end cut here----

WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
To load everything that is needed, execute the commands above...

#----cut here----
# I2C adapter drivers
modprobe i2c-viapro
# I2C chip drivers
modprobe eeprom
# sleep 2 # optional
/usr/bin/sensors -s # recommended

Do you want to generate /etc/conf.d/lm_sensors? Enter s to specify other file name?
(YES/no/s): yes
Done.

I had to add the rc-update command, but the /etc/modules.conf file already had the proper I2C line.

Hmm... got the "No sensors found!" error message. Yet I'm 95% sure that I did everything according to directions. Well, it is an older motherboard so I might be better off retrying setting up lm_sensors on a newer system.

I talked about this a few months ago in Visual Basic Rnd() function tricks and traps, where I discovered that I wasn't getting a full 32bits of randomness out of VB's Rnd() function in my VBScript/Visual Basic pages. At the time, I thought it was simply due to Rnd() returning a 32bit IEEE floating point value which really only has 30bits of data.

In reality, the situation is even worse:

PRNG (Pseudo Random Number Generator) By Michael Meelis
Microsoft Visual Basic: Pseudo Random Number Generator
Using and Creating Cryptographic-Quality Random Numbers By Jon Callas
True random number generators

VB's Rnd() function only provides 24bits of randomness. After the 2^24th sample, it starts repeating. (See INFO: How Visual Basic Generates Pseudo-Random Numbers for the RND Function.)

Randomize() just contributes to the problem. See An Examination of Visual Basic's Random Number Generation By Mark Hutchinson and notice that calling Randomize() is based on the time of the day and only provides around 2^16 different starting points within the 2^24 stream. So if you're calling Randomize() before every Rnd(), you're only getting 16bits of randomness. (It's actually worse, because you'll get identical starting points at the same time of day.)

Looks like there are two basic choices (according to "emerge -s ntp"), ntp and openntpd.

I decided to go with OpenNTPD because it seemed to be smaller and less troublesome then the official NTP daemon. (As one of the lines on the OpenNTPD page says... I'm not after microsecond accuracy.)

If you want to use OpenNTPD, you should dig through the presentations / papers for a brief overview of the project (such as matching time against random servers).

Note that if you're in North America, you'll probably want to change the "servers" line in /etc/ntpd.conf. NTP.org has a list of server pools that you can pick from, divided by geography. I chose to use "north-america.pool.ntp.org" as my servers pool.

(I am still evaluating OpenNTPD... and I may switch over to the official NTP server instead.)

Useful links:
Gentoo Linux Localization Guide
Jeff McCoy | Time

Useful commands:

# hwclock --show
# zdump GMT
# zdump EST5EDT
# date

These commands should show you a hardware clock that matches either GMT (if you have things set to UTC) or your local timezone. I had a misconfigured hardware clock that was set to localtime, while my system was thinking it was UTC/GMT time.

Note that when you look at /var/log/messages, the OpenNTPD messages can be a bit confusing. You will see lines like:

Dec 19 21:33:10 localhost ntpd[5673]: adjusting local clock by -11.800044s
Dec 19 21:36:23 localhost ntpd[5673]: adjusting local clock by -11.691234s
Dec 19 21:39:36 localhost ntpd[5673]: adjusting local clock by -11.621488s

What this actually means is that your clock is currently off by approximately 12 seconds. Eventually, OpenNTPD will adjust your clock to be as close as possible to the official time, but it won't make that adjustment suddenly (all at once). Instead, it will slowly reduce the error amount to the minimum possible for your system.

If you want your server to synchronize at a faster rate, you should manually set the time using the 'date' command to as close to proper time as you can. Otherwise, it may take a few days for OpenNTPD to finish synchronizing your machine's local clock.

You should also look up the "hwclock" command, especially the --hctosys and --systohc options. Also look at "nano -w /etc/conf.d/clock", you should probably set the CLOCK_SYSTOHC flag to "yes" so that your system time gets written to the hardware clock during shutdown.

Hah, I finally flipped the right bit on my AMD64 Gentoo server to eliminate the issue with sluggishness while mdadm is rebuilding a RAID array. So, without further ado, here is my current .config file for a 2.6.13 kernel along with the diff between the last unsuccessful kernel and the kernel that worked.

KernelConfig-1122-0030.txt

KernelConfig-1122-0030-diff.txt

I changed close to a dozen flags when I built the last kernel. One (or more) of them was key in getting rid of the sluggishness.

I now have a few sample kernel configs from kind folks in alt.os.linux.gentoo. There are two that I've focused in on (mostly because they posted first and they gave background on the config files).

2005_1-LiveCDConfig.txt - This is the .config file from the AMD64 2005.1 LiveCD. Since I know this kernel works, it's a prime starting point for researching why I'm having the issues that I'm having.

Anton-AsusK8VSE-Sep2005-config.txt - This kernel config is for an Asus K8VSE, which isn't exactly the board that I'm using (an Asus A8V). However, it is at least a VIA chipset so is pretty relevant. Comparing against this helps to narrow what is different between my kernel, Anton's kernel and the kernel config on the LiveCD.

Scharf-AsusA8V-Aug2005-config.txt - This is a kernel config for an Asus A8V (same motherboard as me). So it will help me verify my particular configuration.

Now for the comparison files. These were created by GNU's diff3 tool on my WinXP laptop, but the output should be pretty standard diff3 output. File #1 is always the LiveCD, file #2 is my current kernel config and file #3 is whatever .config file that I'm comparing against.

LiveCD-vs-Kernel11141600-vs-Anton.txt

LiveCD-vs-Kernel11141600-vs-Scharf.txt

Lines that are the same between the LiveCD and the sample config, but *different* on my config would show up as:

1:35c
3:35c
  CONFIG_HOTPLUG=y
2:36c
  # CONFIG_HOTPLUG is not set

CONFIG_HOTPLUG is set as "y" in both the LiveCD kernel config and Anton's kernel config, but not defined in my kernel config. Naturally, my first pass through the comparison is looking for instances like this and then researching the option to understand whether it should be uniquely set on my system.

Now for the details, I've identified a few troublespots in my kernel config that could be causing issues (these are comparisons against the Scharf config). What I'm finding is that there are very few places in my config where I'm doing something different then the Scharf config (but the LiveCD is the same as the Scharf config).:

1:35c
3:35c
  CONFIG_HOTPLUG=y
2:36c
  # CONFIG_HOTPLUG is not set

Both Anton/Scharf configs set this the same way as the LiveCD.

1:61c
3:60c
  # CONFIG_MODULE_FORCE_UNLOAD is not set
2:62c
  CONFIG_MODULE_FORCE_UNLOAD=y

Both Anton/Scharf configs set this the same way as the LiveCD.

1:110c
3:102c
  # CONFIG_SOFTWARE_SUSPEND is not set
2:120,121c
  CONFIG_SOFTWARE_SUSPEND=y
  CONFIG_PM_STD_PARTITION=""

The software suspend option is probably not the cause of my troubles. Anton's config uses software suspend to a dedicated partition. However, I should still plan on turning this off since I'm not going to use software suspend.

1:211c
3:189c
  # CONFIG_IA32_AOUT is not set
2:211c
  CONFIG_IA32_AOUT=y

Anton configuration has this set to "Y", the Scharf has it not set.

1:895c
3:613c
  # CONFIG_NETCONSOLE is not set
2:591,595c
  CONFIG_NETCONSOLE=y
  CONFIG_NETPOLL=y
  # CONFIG_NETPOLL_RX is not set
  # CONFIG_NETPOLL_TRAP is not set
  CONFIG_NET_POLL_CONTROLLER=y

Mine is the only config to set this to "Y".

1:1597c
3:1334c
  # CONFIG_PROFILING is not set
2:1089,1090c
  CONFIG_PROFILING=y
  CONFIG_OPROFILE=y

Probably not an issue. The Anton config sets this to "Y"/"M" instead of "Y"/"Y".

Updates:

None of the above settings seem to have made any difference.

A) AMD64 / Athlon X2 Opinions - Recommends adding "clock=pmtmr notsc" to the kernel parameters in the grub.conf file. It probably won't help with the sluggishness and lost ticks since those arguments are not being passed on the LiveCD boot.

The LiveCD boots with:

livecd / # dmesg
Bootdata ok (command line is initrd=gentoo.igz root=/dev/ram0 init=/linuxrc looptype=squashfs loop=/livecd.squashfs udev nodevfs dokeymap cdroot vga=791 splash=silent,theme:livecd-2005.1 CONSOLE=/dev/tty1 quiet BOOT_IMAGE=gentoo )
Linux version 2.6.12-gentoo-r6 (root@poseidon) (gcc version 3.4.3 20041125 (Gentoo 3.4.3-r1, ssp-3.4.3-0, pie-8.7.7)) #1 SMP Mon Aug 1 14:22:17 UTC 2005
(snip)

B) Abit AN8 config file from Help with kernel .config (amd64 3000+, s939 nforce4). The poster is also using "pci=biosirq pci=irqroute clock=pmtmr notsc" in their kernel config line.

(haven't tried yet)

C) Config file for an Abit AN8-Ultra. No reported issues by the poster (same thread as #B above).

(haven't tried yet)

D) Turning off power management and CPU frequency options (in both the kernel and the BIOS). A somewhat drastic step, but will allow me to hopefully rule this in/out. This kernel will be my Nov 14th 1500 kernel.

I'm in the process of building this kernel. But after booting and testing with it, no change in the issue.

E) Going to try flipping back to an earlier kernel. I went back to my Nov 8th kernel and merely added in the driver support for sata_promise, the HPT302 chip and the TX2 card (even though the latter two are not installed at the moment). I now have a slightly different "ticks" message:

Losing some ticks... checking if CPU frequency changed.
warning: many lost ticks.
Your time source seems to be instable or some driver is hogging interupts
rip scsi_dispatch_cmd+0x1f3/0x250

I had not seen "rip scsi_dispatch_cmd+0x1f3/0x250" yet. The old message was "rip __do_softirq+0x48/0xb0". Wow, no google hit for the scsi_dispatch_cmd line.

Current broken configuration. Here is the diff between my current configuration and what was on the LiveCD. Left side is the LiveCD config file, right side is my kernel's config file.

AMD64 2005.1 Gentoo LiveCD Kernel Config

I'm still trying to puzzle out what is different on the LiveCD (which works, and which options are causing me grief on the installed kernel). I've even tried adding the "noapic notsc" to my kernel line in grub.conf, but it doesn't fix the issue of sluggishness (it just hides the error).

Time to sit down and jot some things down so I can figure out which device/driver in my Gentoo AMD64 box is causing issues. This gets a little complex because I have (5) 5400rpm 300GB PATA drives, (2) 7200rpm 300GB PATA drives and (1) 7200rpm 200GB SATA drive installed.

Back when I finally booted into the AMD64 LiveCD, I got the following information from /proc/partitions:

livecd ~ # cat /proc/partitions
major minor #blocks name

7 0 49712 loop0
33 0 292970160 hde - 300GB 5400rpm PATA (PDC20269)
34 0 292970160 hdg - 300GB 5400rpm PATA (PDC20269)
57 0 292970160 hdk - 300GB 5400rpm PATA (HPT302)
89 0 292970160 hdo - 300GB 5400rpm PATA (HPT302)
91 0 292970160 hds - 300GB 5400rpm PATA (HPT302)
3 0 293057352 hda - 300GB 7200rpm PATA (motherboard primary IDE)
8 0 293057352 sda - 300GB 7200rpm PATA (PDC20378 m/b)
8 16 199148544 sdb - 200GB 7200rpm SATA (m/b SATA)
livecd ~ #

Key:
HPT302 = HighPoint Rocket133SB PCI cards (1 PATA port per card)
PDC20269 = Promise Ultra133 TX2 PCI card (2 PATA ports)
PDC20378 = Promise RAID controller on A8V motherboard

So, that tells me that if I manage to get my kernel configured properly, I should be seeing all (8) drives with no sluggishness due to oddball drivers. The question of the moment is how do I find out what configuration was used to build the Linux kernel on the LiveCD? That, or I should look into attempting to use "genkernel" to create my settings semi-automatically.

I found the kernel configuration for the LiveCD by booting the LiveCD and looking at the compressed file /proc/config.gz. You can see the contents of this file by using the command:

# cat /proc/config.gz | gzip -d | less

So I went and looked at the differences between my Nov 8th kernel (which works, except for support for the onboard Promise chip and the HPT302s) and my problematic Nov 9th kernel.

nogitsune linux # diff /boot/config-2.6.13-8Nov2005 /boot/config-2.6.13-9Nov2005
4c4
< # Tue Nov 8 18:19:03 2005

> # Wed Nov 9 05:13:43 2005

< # CONFIG_CHR_DEV_SG is not set
---
> CONFIG_CHR_DEV_SG=y
456c456
< # CONFIG_SCSI_SATA_PROMISE is not set
---
> CONFIG_SCSI_SATA_PROMISE=y
nogitsune linux #

That's it. Just two changes to the .config file. So I'm currently undoing the "CONFIG_CHR_DEV_SG=y" line and leaving the Promise SATA line in. I've recompiled and I'm getting ready to reboot to see if it recognizes the PATA disk connected to the PDC20378 chip on the motherboard.

It did, but still didn't fix the issue of sluggishness.

Useful steps to know about when booting off the LiveCD for my system. I manually reassemble the RAID items and mount all of my LVM2 partitions.

The system is very sluggish, even at the console. In addition, the rebuild of my one mirror set is only proceeding at a sedate 3MB/s rather then 10-20MB/s. Looking at "top -n1" shows CPU utilization issues. Compare the first example here (a normal working system) with my trouble system (2nd example):

Cpu(s): 0.2% us, 0.0% sy, 0.0% ni, 99.7% id, 0.0% wa, 0.0% hi, 0.0% si

Cpu(s): 0.9% us, 39.8% sy, 0.0% ni, 6.0% id, 0.3% wa, 1.0% hi, 52.0% si

Key (also see kernel_stat.h):
us = user
sy = system
ni = nice
id = idle (CPU not doing any work)
wa = iowait (time spent waiting for IO to complete)
hi = hardware interrupts (time spent within hardware interrupt handlers)
si = softirq (time spent within other critical sections within the kernel)

You can see the 40% "sy" (system) and 52% "si" (softirq) utilizations on the problem box, with only 6% idle.

This is a record of the kernel flags that I'm going to use for my AMD64 system. It's an Asus A8V (K8T800Pro and VT8237) with an Athlon64 3200+ chip along with 2GB of RAM. Hard drives are hooked up to the onboard Promise controller (PDC20378), the onboard SATA controller and the onboard IDE controller. Plus the motherboard has an onboard gigabit ethernet NIC (Marvell 88E8001).

In addition, I have even more hard drives hooked up to a Promise Ultra133 TX2 PCI card (PDC20269) and some HighPoint Rocket133SB PCI cards (HPT302).

Exit and save your configuration. Then build the kernel (the following command is for 2.6 kernels). Expect the compile to take almost no time at all on an AMD64 chip. I used to wait an hour for all this to happen on my old VIA EPIA.

# make && make modules_install

Once the code finishes compiling, you need to copy the kernel to your /boot partition.

# mount /boot
# ls -l /boot
# ls -l arch/x86_64/boot
# df
# cp arch/x86_64/boot/bzImage /boot/kernel-2.6.13-9Nov2005
# cp System.map /boot/System.map-2.6.13-9Nov2005
# cp .config /boot/config-2.6.13-9Nov2005
# ls -l /boot
# nano -w /boot/grub/grub.conf

Add your new kernel. I'd recommend always leaving the configuration for your old kernel in place and inserting the new config above the old one. That way you get (2) benefits:

1) The "default 0" command will boot the new kernel automatically (because it appears first in the grub.conf file).

2) Your old kernel is still in place, in case the new kernel doesn't boot. There's probably no reason to remove old kernels from the system unless you are running out of space on the /boot partition. (Which is why I use the "df" command to check space.)

Bugs and goofs:

1) The disks attached to the onboard Promise PDC20378 RAID controller are not recognized by my first kernel (although they show up when I booted the LiveCD). So I'm missing a kernel option. Possibly I haven't turned SCSI on which allows me to pick the Promise SATA driver.

This is fixed by adding:

(D)evice drivers
--> (S)CSI device support
--> --> (S)CSI low-level drivers
--> --> --> (S)erial ATA (SATA) support (should already be ON)
--> --> --> --> (P)romise SATA TX2/TX4 support (turn ON as BUILT-IN)

1b) However, once you've turned on that particular driver (CONFIG_SCSI_SATA_PROMISE=y), your system will slow down and become very sluggish anytime that mdadm is rebuilding an array with drives attached to that controller. You will also start to see the following messages in your "dmesg" output:

warning: many lost ticks.
Your time source seems to be instable or some driver is hogging interupts
rip __do_softirq+0x48/0xb0

2) The disks attached to the PCI Rocket133 cards did not show up after the first boot. Same deal as #1, worked with the LiveCD, but I didn't get the driver selection right when I built the first kernel. On the upside, it allowed me to identify the (2) disks that are attached to the Promise PCI controller without any effort (hde and hdg are on the Promise card).

(I'm still troubleshooting the Rocket133.)

Key things to look for in menuconfig for Rocket133 might be:

(D)evice drivers
--> ATA/ATAPI/MFM/RLL support
--> --> SCSI emulation support
--> --> generic/default IDE chipset support
--> --> PCI IDE chipset support
--> --> Generic PCI IDE Chipset Support

Probably the only one that matters is (CONFIG_BLK_DEV_HPT366=y):

--> --> HPT36X/37X chipset support (turn this ON as BUILT-IN)

Yes, the Rocket 133SB (Rocket133SB) HPT302 chip is apparently supported by the HPT366.c file. You can find this by grepping the kernel sources:

# cd /usr/src/linux
# find . -print | xargs grep -i 'hpt302'
# grep -i 'hpt366' .config

...

So, after turning on the two drivers I have all 8 drives showing up against in /proc/partitions:

hde / hdg -- Promise PCI card
hdk, hdo, hds -- Highpoint Rocket133 cards
hda -- motherboard IDE
sda -- Promise motherboard RAID PATA
sdb -- motherboard SATA

Performance is still slow, so now I'm digging through the kernel configs trying to find lines that contain "irq".

One key line that look interesting:

Sharing PCI IDE interrupts support (CONFIG_IDEPCI_SHARE_IRQ)

Turned that on, but still haven't fixed the sluggishness or the lost ticks issue. I'm very tempted to give up on the PDC20378 chip, except that I know it worked on the LiveCD.

Labels: 2005, Gentoo, SoftwareRAID

So, I was going to rebuild my 1Ghz Athlon machine with 640MB, but in the process of transplating hard drives and installing a new (quieter) CPU fan, I seem to have put it down for the count. Moderate annoyance only as it's an older motherboard and was nearing the end of its lifespan. (I may try and troubleshoot it next week.)

Instead, I replaced with an Asus A8V Deluxe (VIA chipset, BIOS version 08.00.09 05/19/05) motherboard with an Athlon64 3200+ and 2GB of RAM. In addition, I have (8) 300GB hard drives hooked up to this unit. The (2) RAID1 boot drives are 7200rpm (hooked to the primary IDE port and the 2nd one on the Promise FastTrak RAID port). The other (6) drives are 5400rpm drives hooked up to a Promise SX6000 card.

Now, I'm not sure that I can have both the onboard FastTrak and the SX6000 running at the same time. (If not, I have a 1-port ATA/133 PCI HighPoint card that I can use for the 2nd boot drive.)

Tossed the Gentoo 2005.1 boot CD in. The graphical splash screen loads, and it starts counting through devices. At "Booting the system (64%)", I get a kernel panic and it stops booting. The screen now reads (approximately):

kernel BUG at <bad filename>:55433!
Invalid operand: 0000 [#1]
PREEMPT SMP
Modules linked in: ...
(bunch of registers)
Process swapper (pid: 0 ...
(trace dump)
<0> Kernel panic - not syncing: Fatal exception in interrupt

Pressing [F2] does nothing at this point.

Attempting to boot Knoppix 4.0.2 CD results in the boot CD hanging during device initialization. But if I boot the Knoppix CD as "failsafe" it loads correctly.

Attempted fix #1:

Disable the onboard Promise FastTrak controller (since I have a Promise SX6000 installed in a PCI slot). In past Windows systems (FastTrak66 and FastTrak100 cards), their documentation indicates that you should not have two FastTrak cards installed at the same time. Whether this applies to a SuperTrak and FastTrak pairing, I'm unsure.

Still got the error. It's probably not the Promise cards.

Attempted fix #2:

Re-enable the Promise FastTrak controller (setting it as "IDE mode"), and check boot options on the Gentoo Universal LiveCD. Since this is a single-core Athlon64, I'm going to try the NOSMP flag. This involves intervening in the boot process when the LiveCD reaches the "boot:" prompt. You can then type "gentoo nosmp" to boot the kernel without SMP support.

No luck, system hangs when initializing the kernel (I'm wondering if NOSMP is even a boot option on the LiveCD).

Attempted fix #3:

Check for a newer version of the BIOS at Asus Support. (One person's experience with flashing an A8V.)

No luck. System still bombs out with a kernel error.

Attempted fix #4:

Downloaded the AMD64 version of the 2005.1 Universal LiveCD. This still gives me a kernel bug, but it bombs out with a more descriptive error (rather then saying "bad filename".) The kernel is bombing on "include/linux/i2o.h:517".

One note indicates that it's a bug between the SX6000 card and the Linux kernel. One suggestion indicates that you should go into the SX6000 BIOS (hitting Ctrl-F when prompted after it scans the arrays) and set the operating system type to "Other OS". (Tried this, no luck.)

Currently, I'm using 1.10 build 15 version of the BIOS (B77 from June 2002), and I see that there is a newer 1.20.0.27 from April 2004 on the Promise.com website. So I'll go ahead and try patching up the Promise BIOS. (Tried this as well, the SX6000 refuses to flash in this system. I'm getting an error message while trying to usethe flash tool. I'll try the card in another system and see if that works better.)

Attempted fix #5:

Ripped the SX6000 out. I replaced it with (1) FastTrak133 TX2 PCI card and (3) HighPoint Rocket133 PCI cards. I also converted one of the drives over to SATA, using the on-board SATA port. (Think of this as a poor-man's setup.) I had a bunch of the Rocket133 cards laying around, and the system doesn't seem to care that I have multiple cards installed.

(My first attempt, used a pair of FastTrak133 TX2 PCI cards, but that caused the system to lockup when I went into the BIOS setup.)

I'm currently running DBaN at the moment to test the configuration (PRNG mode, multiple passes, verifying all passes). It identified 7 of the 8 drives (the onboard Promise RAID chip is unknown to this version of DBaN) and is writing to all 7 at the same time with no errors. I'm getting 10MB/s to each drive with a load average of around 8.0. Once I let that run for another hour or two, I'll switch back to trying the AMD64 Gentoo CD.

Booted into the AMD64 Gentoo CD with zero issues. My drives are:

livecd ~ # cat /proc/partitions
major minor #blocks name

7 0 49712 loop0
33 0 292970160 hde
34 0 292970160 hdg
57 0 292970160 hdk
89 0 292970160 hdo
91 0 292970160 hds
3 0 293057352 hda
8 0 293057352 sda
8 16 199148544 sdb
livecd ~ #

Basically, hda & sda are my (2) 7200rpm 300GB drives that I'm going to use as my primary RAID1. The sdb drive is my 200GB 7200rpm SATA which I plan on using for a scratch drive. The rest of the drives (all ending in "160" blocks) are 5400rpm 300GB IDEs hooked to the Highpoint / Promise PCI cards.

Now I can go ahead and build my system.

In order to install "denyhosts", you'll probably have to muck with application specific keywords. See USE flags (gentoo.org) or FAQ USE Flags (Gentoo Linux Wiki). Look for information on editing the "/etc/portage/package.keywords" file. The current version of denyhosts is tagged with "~x86" (indicating that it compiles, but has not been verified?).

I'm still searching for a solution to this issue. I've heard it has to do with trying to use the kerberos USE flag (which is not an optional flag for me). The closest possible solution in Google is on the Gentoo forums (Problems upgrading to Samba 3.0.14a-r2!). The user, "jpnag", posts a solution.

The solution involves editing the ebuild file for Samba. This is where you will need to become a bit more knowledgeable about how portage and emerge works (see "man make.conf" for details on some of this along with "man portage").

By default, portage downloads and installs packages under the "/usr/portage/" tree (defined by "PORTDIR=" in your "/etc/make.conf" file or "/etc/make.profile/make.defaults" file). There is also an optional define, "PORTDIR_OVERLAY=", which you can use to point at a tree containing user-built ebuild files that are not updated by "emerge --sync". Essentially, the second tree will overlay the first. So if you have "package X" in both trees, only the one in the overlay tree will get compiled.

Now to create the backup copy of the broken Samba ebuild. If you have not already added "PORTDIR_OVERLAY=" to your "make.conf" file, you should also do this.

# cd /etc
etc # echo 'PORTDIR_OVERLAY="/usr/local/portage"' >> /etc/make.conf
etc # cd /usr/local
local # ls /usr/portage/net-fs/samba/
local # mkdir portage ; cd portage
portage # mkdir net-fs ; cd net-fs
net-fs # mkdir samba ; cd samba
samba # cp -a /usr/portage/net-fs/samba/* .
samba # ls -l samba-3.0.14a-r2.ebuild
samba # nano -w samba-3.0.14a-r2.ebuild

Now hit [Ctrl-W] and type "src_compile", which will take you straight to the following code block:

rc_compile() {
        ebegin "Running autoconf"
                autoconf
        eend $?

        local myconf
        local mymods
        local mylangs

        if use xml || use xml2 ;
        then   
                mymods="xml,${mymods}"
        fi

Somewhere towards the start of the funciton, add the line "addpredict /etc/krb5.conf".

src_compile() {
        ebegin "Running autoconf"
                autoconf
        eend $?

        local myconf
        local mymods
        local mylangs

        addpredict /etc/krb5.conf

        if use xml || use xml2 ;
        then
                mymods="xml,${mymods}"
        fi
