Debian Lenny: how to configure grub and fstab for updating multipath kernel initrd images
High end x86 / amd64 machines may fail to boot updated Debian GNU/Linux 5.x Lenny kernel images.
Multiple fast CPUs, multiple fast network cards, multiple Fiber Channel Host Bus Adapters (HBA), multiple SCSI arrays adapters, may cause a boot failure of updated kernel images. Notably when you have multipath, dm-raid, iSCSI or other device mapper ones, for example.
High end fast machines may cause boot failures
When you update your Debian GNU/Linux 5.x Lenny kernel package and or execute an update-initramfs command to include a new device driver, at the boot sequence you may get stuck at console messages SIMILAR to:
Decompressing Linux... Parsing ELF... done. Booting the kernel. Loading, please wait... Discovering multipaths... libdevmapper: libdm-common.c(312): created /dev/mapper/36005076308ffc36c000000000000000f libdevmapper: libdm-common.c(312): created /dev/mapper/36005076308ffc36c000000000000000e .... kinit: name_to_dev_t(/dev/sda2) = sda2(8,2) kinit: trying to resume from /dev/sda2 kinit: no resume image, doing normal boot... mount: mounting /dev/sda3 on /root failed: Device or resource busy. mount: mounting /dev on /root/dev failed: No such file or directory. mount: mounting /sys on /root/sys failed: No such file or directory. mount: mounting /proc on /root/proc failed: No such file or directory.

Why is it happening?
Several parallel asynchronous threads looking for (fast and inteligent, with their own cpu / bios) devices during the initialization step may cause REORDERING and RENUMBERING at device mapper tables changing pointers to other real or virtual devices than those configured at the initrd images, grub and /etc/fstab.
This causes that programs that need device definitions and also the initrd boot images become "somewhat ramdomized" because their device mappings become "somewhat ramdomized" and MAY be differet at each boot.
Beware of device detection latencies
Beyound that, the internal BIOSes of FC HBA, SCSI controllers, network cards, iSCSI, may take some time for initialization and hand-shake with routers, switches and backend FC/iSCSI servers, that even have their own latencies variable on their own load for other concurrent clients.
These increase the entropy of the whole process.
Be sure to use a security updated udev version
Triple check that you have installed the most security updated udev version for your Debian distribution version.
Did I already say that you need to check you have the updated udev package version before start?
Be sure to have the device driver packages available
Some FC and network adapters in corporate environments are in the non-free debian repository section. Be sure to have this section enabled at your /etc/apt/sources.list.
Read the apt pinning article and the sources.list examples .
Configure grub and fstab BEFORE configuring multipath
Follow this very document before even trying to install multipath and lvm2 or you will have an unbootable machine (maybe thousand miles away...).
Solution 1: use the disk-id to identify and define the devices
The UUID are filesystem attributes, that "can" be modified and or reused by programs like the device mapper.
The identifiers /dev/disk/by-id/* are hardware attributes and "reasonably immutable".
At least until a partition table modification or disk changing/substitution be done.
Therefore, we will use disk-id to workarund conflicts and double UUID mappings by udev and device mapper.
Discover the detected system /dev/disk/by-id/*

Make a backup
corp-bsa-exp-nuvem02:~# cp /boot/grub/menu.lst /boot/grub/menu.lst.old1
Using the /dev/disk/by-id from our example, edit the Debian automagic grub option. The single # is important!
## AFM 22oct2010 ## kopt=root=/dev/sda3 ro # kopt=root=/dev/disk/by-id/scsi-360026b9038e754001270c9de079bca7c-part3 ro rootdelay=15 nodmraid
Be careful with strict format. There are no double quotes nor undue blank spaces at the root device definition that will be used for future kernel image updates.
Kernel option rootdelay
Rootdelay makes the image load to mount kernel root filesystem to delay some amount of seconds, causing the device detection and mapping to delay.
Adjust the time in order to guarantee that all HBA, network cards, SCSI controllers, FC switches and routers handshakes, backend FC / iSCSI storage latencies, etc, become ready.
Update the /boot/grub/menu.lst with the same script used by the kernel package updates
Therefore, at future kernel package update, the configurations will be always correct.

Kernel option nodmraid
SOME kernel versions honors this option. It may be useful if you do not have software raid at your host, to avoid some collisions. You may not use it if not needed for your system.
Configure /etc/fstab
Make a backup.
corp-bsa-exp-nuvem02:~# cp /etc/fstab /etc/fstab.old

depmod
You MAY have to remap drivers to boot.
By now, it is very likely that you DO NOT NEED, because your system was able to boot before GIVEN THAT THE HARDWARE is UNMODIFIED.
But if you move the /boot partition to a storage LUN, for example, you will NEED it mapped at the very instant of kernel boot.
Do not remap dependencies if you are not sure that you need it.

Examine the list and TRIPLE check that the needed drivers are at the image.
Compare the /boot directory with the backup contents:

Take note of the *.bak image. You may have to recover from a boot failure and boot from it in an emergency.
Now you could test the new image:
corp-bsa-expresso-nuvens02:~# reboot
If sucessful, then you could go for multipath, lvm2, filesystem configuration and tuning.
Solution 2 (OBSOLETE for our machines): use UUID for device definitions
Instead of using /dev/xxx at grub, fstab and generate initrd images, we will identify devices by their UUID, including swap.
How discover devices UUID
corp-bsa-exp-nuvem01:~# blkid /dev/sda1: UUID="87f2b245-6ab3-4021-bf07-d069b4d387a1" TYPE="ext3" /dev/sda2: TYPE="swap" /dev/sda3: UUID="a6f7a63f-71ac-4361-b49a-39d62b06f18a" TYPE="ext3" corp-bsa-exp-nuvem01:~#
As you can see, the swap partition filesystem does not have an UUID yet, wich is a problem now.
The Debian Lenny installer does not attribute an UUID to the swap partition. But it has solution.
How attrib an UUID to swap partition
First, securely deactivate swap
corp-bsa-exp-nuvem01:~# swapoff /dev/sda2
Recreate the swap partition, get its UUID, reactivate swap and verify result:
corp-bsa-exp-nuvem01:~# mkswap /dev/sda2
Setting up swapspace version 1, size = 1998737 kB
no label, UUID=7cdfeb21-613b-4588-abb5-9d4049854e9a
corp-bsa-exp-nuvem01:~# blkid
/dev/sda1: UUID="87f2b245-6ab3-4021-bf07-d069b4d387a1" TYPE="ext3"
/dev/sda2: TYPE="swap" UUID="7cdfeb21-613b-4588-abb5-9d4049854e9a"
/dev/sda3: UUID="a6f7a63f-71ac-4361-b49a-39d62b06f18a" TYPE="ext3"

corp-bsa-exp-nuvem01:~# cp /boot/grub/menu.lst /boot/grub/menu.lst.old1
Edit the following part using the discovered UUID
## AFM 19oct2010 ## kopt=root=/dev/sda3 ro # kopt=root=UUID=a6f7a63f-71ac-4361-b49a-39d62b06f18a ro rootdelay=15
Be careful with strict format. There are no double quotes nor undue blank spaces at the root device definition that will be used for future kernel image updates.
Kernel option rootdelay
Rootdelay makes the image load to mount kernel root filesystem to delay some amount of seconds, causing the device detection and mapping to delay.
Adjust the time in order to guarantee that all HBA, network cards, SCSI controllers, FC switches and routers handshakes, backend FC / iSCSI storage latencies, etc, become ready.
Update the /boot/grub/menu.lst withe same script used by the kernel package updates
Therefore, at future kernel package update, the configurations will be always correct.

depmod
You MAY have to remap drivers to boot.
By now, it is very likely that you DO NOT NEED, because your system was able to boot before GIVEN THAT THE HARDWARE is UNMODIFIED.
But if you move the /boot partition to a storage LUN, for example, you will NEED it mapped at the very instant of kernel boot.
Do not remap dependencies if you are not sure that you need it.
corp-bsa-exp-nuvem01:~# depmod
Recreate the kernel initrd
Make a /boot directory backup preserving permissions, ownership, links, timestamps

Update the most recent kernel image. The -v option will produce LOTS of output. Send it to a file for careful reading BEFORE the next boot.

/etc/blkid.tab
This cache file content should be similar to:

Compare the content with a misdetected system file:
<device DEVNO="0x0801" TIME="1287603090" UUID="0b0ba0cd-23af-4368-bc3d-9696af6b331a" TYPE="ext3" SEC_TYPE="ext2">/dev/sda1</device> <device DEVNO="0x0802" TIME="1287603090" TYPE="swap" UUID="1fe8cfb3-7b27-48e7-9114-92320e97e946">/dev/sda2</device> <device DEVNO="0x0803" TIME="1287603090" UUID="62bfb170-a31b-47ef-b64f-1b8d6f6503c2" TYPE="ext3">/dev/sda3</device> <device DEVNO="0xfe04" TIME="1287602906" UUID="0b0ba0cd-23af-4368-bc3d-9696af6b331a" SEC_TYPE="ext2" TYPE="ext3">/dev/dm-4</device> <device DEVNO="0xfe07" TIME="1287603090" TYPE="swap" UUID="1fe8cfb3-7b27-48e7-9114-92320e97e946">/dev/dm-7</device> <device DEVNO="0xfe08" TIME="1287602585" UUID="62bfb170-a31b-47ef-b64f-1b8d6f6503c2" TYPE="ext3">/dev/dm-8</device>
Notice that are UUID DUPLICATION for DIFFERENT devices.
This machine would not boot.
This is the motivation for considering this solution 2 obsolete and now we are using /dev/disk/by-id/* identifiers.
IF the blkid generate a correct /etc/blkid.tab file, then you could test the new image:
corp-bsa-expresso-nuvens01:~# reboot
If sucessful, then you could go for multipath, lvm2, filesystem configuration and tuning.
