moin moin,
I'm trying to install CentOS 5.0 on a 3ware driver that doesn't have
support in the install kernel.
3ware provided a driver that insmods just fine and I can see the RAID
device.
I can then do an install, but upon reboot the kernel panics.
###
Trying to resume from LABEL=SWAP-sda5
Unable to access resume device (LABEL=SWAP-sda5)
Creating root device.
Mounting root filesystem.
mount: could not find filesystem '/dev/root'

I was able to boot the rescue image, load the 3ware module and open up the
initrd being used for the boots. The initrd has the 3ware module as well
as the scsi_mod driver and ext3 driver. It looks like everything is there.
I can also see in the boot that the 3ware driver gets loaded and the 3ware
device gets recognized.
I've tried both 64 bit and 32 bit installs.
Any ideas as to what module is missing? Is it something else?

Don't have access to the box right now.
/etc/fstab
Lists the mounts via LABEL. All the LABEL pieces seem correct to me.
/etc/modprobe.conf
Didn't look at that.
I would make certain that the proper 3ware module is listed
in /etc/modprobe.conf BEFORE you 'mkinitrd' again.
Since it's getting into the initrd I figured I'm fine.
I am not knowledgeable about 3ware cards but have definitely done
similar making older megaraid cards work on CentOS-4
The basic process is to boot rescue disk, insmod the module, mount the
disk, chroot to the root of the 3ware drives, verify /etc/modprobe.conf
is correct and then cd to /boot, mkinitrd
initrd-2.6.20-xxxEL-whatever.img.copy 2.6.20-xxxEL-whatever then move
the new initrd.img file over the old one.
Yeah, I was chrooting into /mnt/sysimage in trying to repair things.
Environment setup was shot that way :(.
As I was running out of time I noticed that the filesize of the module in
the initrd is significantly smaller than the filesize of the module from
the zip file from 3ware.
I was thinking this is a different module with a different name than any
others in the kernel. That might not be the case. Looks like I'll have to
fix the chroot environment well enough for mkinitrd to work.
Thanks for the ideas.
There are LOTS of people who work with 3ware cards on CentOS mail
list...
I hopped in one of the IRC channels and asked for help. Nothing
substantial came back. Didn't really expect it, but since I was on a
limited time budget I went for the live support option :).
ciao,
