The only thing that worries me about MD in 2.6.12 is that if you
simulate a total disk failure (unplug the power cord in a running disk),
MD just freezes the system for an hour (actually not the whole system,
but any process which tries to access the filesystem on the array hangs
until MD has done 100 retries, one every 30 seconds) as the disk appears
"Busy", instead of just using the other disk.

This _seems_ fixed in 2.6.14 (the code has changed, so I supposed it's
better now, but I haven't actually tested this yet - maybe someone here
has?).

Otherwise typical disk failures get managed by MD just fine.
