Package: mdadm
Version: 2.5.2-10
Followup-For: Bug #382263
After rebooting following the last mdadm upgrade, dmesg reported:
md: md driver 0.90.3 MAX_MD_DEVS=256, MD_SB_DISKS=27
md: bitmap version 4.39
md: raid1 personality registered for level 1
md: md0 stopped.
md: bind<hdb3>
md: bind<hda3>
raid1: raid set md0 active with 2 out of 2 mirrors
Attempting manual resume
Then bootlog reported:

running).

As a quick hack I was able to mount the mirrored /dev/hda3 /dev/hdb3
using /dev/md/0 instead of the missing /dev/md0 as shown in the mount
output below.
