Package: mdadm
Version: 3.0-2
Severity: normal
I upgraded grub and mdadm this afternoon, and whilst the process appeared
successful,
after rebooting the system would not come up - my mirrored root device was
seemingly
gone.
Attempting to start it from the mdadm included in my initrd failed, claiming
that
there is no raid on /dev/hda1 nor /dev/hdb1 (where md0 lives). It did however
happily
start my raid5 array on /dev/sda1 and /dev/sdb1 (md1 - lvm host).
Lacking any other initrd images to work from, I booted up to a partedmagic live
cd,
which using a 2.x version of mdadm, happily assembled my raid1 array. Once
mounted, I
noticed a backup initrd image in my /boot directory, which when used in place
of the
generated one, brought the system right up. mdadm 3 is happily working with my
raid1
array now the system has booted.
It's been a fraught afternoon - this was my internet router...so I've been
reading
this bug report on my mobile phone as a reference as I had no other access!
