Upgrade kernel error: FATAL: Hook 'raid-partitions' can not be found.

Hi,

while upgrading Arch, on kernel upgrade I got this error:

FATAL: Hook 'raid-partitions' can not be found.

This is the first time I got this error (hmm..., for more than a year any kind of error )

Well, I have RAID level 1 (mirroring).

Here is my /etc/mkinitcpio.conf

MODULES="pata_acpi ata_generic scsi_mod ata_piix"
BINARIES=""
FILES=""
HOOKS="base udev autodetect pata scsi sata raid raid-partitions keymap usbinput filesystems"

$ uname -srv
Linux 2.6.28-ARCH #1 SMP PREEMPT Tue Mar 17 06:42:43 UTC 2009

This means that kernel is not upgraded yet?
ATM I don't want to reboot machine and run into kernel panic.

Any help to get this raid-partitions hook working appreciated.

The raid-partitions hook has been replaced by a new one: mdadm. Replace raid-partitions by mdadm in your /etc/mkinitcpio.conf and run 'pacman -S kernel26'. That will update the kernel if it hasn't been done (I can't tell from what you posted) and will regenerate your initcpio image. I believe that's all you need to do.

I thought it was just 'raid'? That's what I'm using with my RAID-1 and it works OK... :s

EDIT: Just read the mail list archive, and if I understand correctly, the 'mdadm' hook replaces 'raid' (not 'raid-partitions')?

There is a raid hook provided by mkinitcpio and a mdadm hook provided by mdadm. I was using the raid hook but I switched to the mdadm one in order to test it (ML link). I'm now using the mdadm one (RAID5). The mdadm hook has extra functionality compared to the raid one.

The raid-partitions hook was removed in favor of mdadm: http://repos.archlinux.org/viewvc.cgi/m … 5&r2=29447

Is there any advantage to using the mdadm hook as opposed to having your RAID configuration specified in GRUB's configuration file? Because that's how I am doing it now (and it's never broken).

fukawi2 · 2009-04-24 09:20:52

Maybe it could solve this problem?

That's a good idea... Did you try already? Didn't think of that.

fukawi2 · 2009-04-24 10:45:57

Will try and report back.

Solved

Thanks.

Wiki doesn't seems to point that out.

As stated here, can I remove:
- raid hook
from /etc/mkinitcpio.conf
- md=0,/dev/sda1,/dev/sdb1 md=1,/dev/sda2,/dev/sdb2 part of line
from grub/menu.lst (kernel /vmlinuz26 root=/dev/md1 ro md=0,/dev/sda1,/dev/sdb1 md=1,/dev/sda2,/dev/sdb2)

?

Yes, this does solve the issue in the post I linked to above

I have updated a few wiki pages, mainly this one:
