Yeah, Promise RAID s*cks :-(
I have a bunch of servers running 7.3 which were installed with the
proprietary driver and contain an onboard Promise IDE RAID controller. I've
been able to use the ataraid and pdcraid modules of the latest errata
kernels on them, but the transition was a bit tricky as the Promise driver
makes the devices appear as SCSI devices, whereas the free drivers make
them appear in /dev/ataraid/. Also, I've got severe data corruption issues
with 2.4.2x kernels, so I had to downgrade to the latest 2.4.18 errata one
to fix that. I still have a bugzilla bug open about this one...
If you want my advice : Disable completely the Promise RAID stuff, and if
you can get the drives to appear as regular IDE devices, you'll be much
better off using software RAID!
Here is basically what I did, in case your situation is similar. The 2.4.18
kernel can still be found here :
http://ftp.freshrpms.net/pub/freshrpms/redhat/misc/kernel-2 (See http://nel-2.ora-code.com).4.18-27.7.x/
apt-get update
apt-get install modutils
apt-get install kernel-smp#2.4.18-27.7.x
mkinitrd --omit-scsi-modules --with=ataraid --with=pdcraid
/boot/initrd-2 (See http://trd-2.ora-code.com).4.18-27.7.xsmp.img 2.4.18-27.7.xsmp
edit /etc/grub.conf to :
- Add the new initrd file!!!
initrd /boot/initrd-2 (See http://trd-2.ora-code.com).4.18-27.7.xsmp.img
- Replace root=/dev/sda1 with root=/dev/ataraid/d0p1
- Change to default=0 (the new kernel)
edit /etc/fstab :
- Replace /dev/sda8 (swap) with /dev/ataraid/d0p8
- reboot -
rpm -e kernel-2 (See http://nel-2.ora-code.com).4.18-3 kernel-smp-2 (See http://smp-2.ora-code.com).4.18-3
remove the FastTrak line from /etc/modules.conf and add :
alias scsi_hostadapter0 ataraid
alias scsi_hostadapter1 pdcraid
- re-reboot and done! -
