Just upgraded a poweredge 1850 server from Debian lenny to squeeze and can not
boot with the new 2.6.32 kernel.
From lspci have this controller:
SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT
Dual Ultra320 SCSI (rev 08)
Running mdadm raid with root on md0.
Normally run xen but all info is for when running without xen.
I can still boot with the 2.6.26 kernel but not with the new 2.6.32 kernel.
Under 2.6.32 it fails to start md0.
in the busy box console
Can see all the needed partitions.
What was sda and sdb are now sdb and sdc that should not matter??
mdadm.conf is:
DEVICE partitions
CREATE owner=root group=disk mode=0660 auto=yes
HOMEHOST <system>
MAILADDR xxxxx@advocap.org
ARRAY /dev/md0 level=raid1 num-devices=2
UUID=6f744c89:d2578f95:c150b018:d9f789b1
ARRAY /dev/md1 level=raid1 num-devices=2
UUID=7938d59c:28a69e5e:3facbdc2:12974557
raid1 mptbase mptscsih and mptspi module are loaded.
Looks right but does not start md0.
Any ideas?
Thanks
John

This is probably due to udev changes. What device is now sda?
Using drive UUIDs instead of /dev/sdx in your arrays should fix this.

I think sda is a cd or virtual cd now.
In the mdadm.conf it uses uuids and no /dev/sdx references or are you
referring to something else?

How is /dev/md0 assembled in your initramfs? You said your root
filesystem is on /dev/md0. Thus /dev/md0 must be assembled before
/etc/mdadm.conf can be read.
Another way around this problem is to create persistent udev rules. But
since this requires created one-to-one mappings between
/dev/sdx<->drive_UUID mappings, it is easy to simply have mdraid use
drive UUIDs across the board, including within initramfs.

The /etc/mdadm/mdadm.conf file is in the initramfs and is referenced by
the /scripts/local-top/mdadm script.
If I run it manually it starts raid Ok and I can mount /dev/md0
I'm not sure how on gets it to complete the boot process.

I just did another attempt.
After it failing I did the following from the

The problem was it was starting mdadm before the scsi driver was done
initializing.
Found solution at http://wiki.debian.org/InitramfsDebug
Added kernel parameter scsi_mod.scan=sync
Ran in to this years ago but forgot :-(
