[opensuse] Recover md RAID-1.

How do I recover a broken MD RAID-1.... Since there is no way to make
a backup with easy restore? I boot the system and it says:


md: radi5 personality registered
md: raid4 personality registered
md: md0 stopped.
md: bind<sdb1>
md: bind<sda1>
md: md0: raid array is not clean -- starting background reconstruction
raid1: raid set md0 active with 2 out of 2 mirrors
md0: bitmap file is out of date (8 < 9) -- forcing full recovery
md0: bitmap file is out of date, doing full recovery
md0: bitmap initialisation failed: -5
md0: failed to create bitmap (-5)
md: peers -> run() failed...
mdadm: failed to RUN_ARRAY /dev/md0: Input/output error
mdadm: device /dev/md0 already active - cannot assemble it
Trying manual resume from /dev/sdb2

Before this system was working fine. I shut it down correctly with the
'halt' command. I plugged in a USB KVM that makes the system hang at
boottime (to provide needed info for Bug # 412476) after the system
hung I powered it off, unplugged the kVM and then booted it back, only
to get the above messages.
