Public bug reported:
Binary package hint: mdadm
I have a fresh installation of Ubuntu 8.04 which has three harddisks
(all ide, pata disks):
/dev/sda (contains '/' on /dev/sda1 and swap on /dev/sda2)
/dev/sdb
/dev/sdc
I would like to create a raid 1 array of sdb and sdc.
Everything runs fine until I installed mdadm. I tried directly after installing
mdadm to create a raid1 (mirror) array with
mdadm --create /dev/md0 --raid-devices=2 /dev/sdb /dev/sdc
This caused my system to freeze. After I tried to reboot, the system froze
during booting.
Next thing I tried was installing mdadm on a clean Ubuntu 8.04 installation,
and reboot before creating any raid arrays. This also caused a freeze of the
system during the boot process. I tried booting with the failsafe option in the
ubuntu boot menu, this throws me back to a 'busybox':
(initramfs):
If I try to execute some commands, the system freezes after a short while.
I tried booting the system with the ubuntu live cd so I could edit the
mdadm.conf file. I changed the following lines:
DEVICE /dev/sdb /dev/sdc # (not sure anymore what the default value was)
# (commented this one out, because I didn't specify any arrays yet)
# ARRAY /dev/md0 level=raid1 num-devices=2 UUID=....
After that I wasn't dropped back to the busybox, but the system still
froze during the boot process. I am now out of options and I have no
clue what is actually going on here or how I could possibly fix this so
I can boot my system. It seems the system just freezes when mdadm tries
to build an array (while I didn't specify anything), it also freezes
when I did specify the right disks.
Another thing which I am not sure about:
when I boot using the live cd, and I mount /dev/sda1, it lists a lot of md
devices in the mounted /dev/md* (ranging from md0 to md31). Is this normal
behavoir?
Greetings,
Heiko
