I'm running

uname -a Linux server 2.6.27.7-9-default #1 SMP 2008-12-04 18:10:04 +0100 x86_64 x86_64 x86_64 GNU/Linux

I've patched OS 11.1's "/lib/mkinitrd/scripts/setup-md.sh", per,

"Bug 461673 - xen/kernel-xen on OpenSuse 11.1 not starting; OK on OpenSuse 11.0" https://bugzilla.novell.com/show_bug.cgi?id=461673

my setup is RAID-1 based,

disks sdc+sdd /boot on /dev/md0, fmt=ext3 swap on /dev/md1, fmt=swap /root on /dev/md2:VG(VG_Dom0):LV(LV_ROOT), fmt=ext3 /home/store on /dev/md3:VG(VG_DomU):LV(store), fmt=ext3 /home/work on /dev/md3:VG(VG_DomU):LV(work), fmt=ext3 disks sda+sdb 'other' on /dev/md4 'other' on /dev/md5

& boots OK,

df -H Filesystem Size Used Avail Use% Mounted on /dev/mapper/VG_Dom0-LV_ROOT 13G 5.5G 6.6G 46% / udev 4.2G 213k 4.2G 1% /dev /dev/md0 152M 53M 91M 37% /boot none 68M 0 68M 0% /tmp /dev/mapper/VG_DomU-store 5.3G 4.5G 572M 89% /home/store /dev/mapper/VG_DomU-work 11G 451M 9.6G 5% /home/work

with all RAID devs available (i'm curious/concerned about the "resync=PENDING .. tbd later ...),

cat /proc/mdstat Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [linear] md5 : active (auto-read-only) raid1 sda2[0] sdb2[1] 347606300 blocks super 1.0 [2/2] [UU] resync=PENDING bitmap: 332/332 pages [1328KB], 512KB chunk

If I reboot this setup to single user,

title OS 11.1 SINGLE_USER root (hd0,0) kernel /vmlinuz single root=/dev/system/ROOT iommu=force irqpoll initrd /initrd

@ shell prompt,

ls /boot

is completely empty. looks like /boot on /dev/md0 is not mounted at all.

checking

cat /proc/mdstat Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [linear] md1 : active (auto-read-only) raid1 sdc2[0] sdd2[1] 522100 blocks super 1.0 [2/2] [UU] bitmap: 0/8 pages [0KB], 32KB chunk

md2 : active raid1 sdc3[0] sdd3[1] 12578820 blocks super 1.0 [2/2] [UU] bitmap: 7/192 pages [28KB], 32KB chunk

md0, md3, md4 & md5 are missing.

md4/5, i suspect, because the associated drives are hanging off of a PCI/SATA card ... but shouldn't md0 & md3 both be there & mounted?

attempting to mount

mount -a mount: special device /dev/md0 does not exist mount: special device /dev/VG_DomU/store does not exist mount: special device /dev/VG_DomU/work does not exist

they're apparently not-mountable :-/

Reading @ possibly relevant,

Bug 445490 - boot stops on mounting a software RAID - Invalid root filesystem https://bugzilla.novell.com/show_bug.cgi?id=445490#c19

it looked worth a try. applying the referenced patch to,

/lib/mkinitrd/scripts/boot-md.sh

and rebooting, unfortunately, makes no difference; md0/3/4/5 are still missing in single-user.

Reproducible: Always
