Says who? (Don't use LILO ;-)

I like LILO :)

LILO cares much less about disk layout / filesystems than GRUB does,
so I would have expected LILO to cope with all sorts of superblocks.
OTOH I would suspect GRUB to only handle 0.90 and 1.0, where the MDSB
is at the end of the disk <=> the filesystem SB is at the very beginning.

So two questions:

1) If it rebuilt by itself, how come it only rebuilt /dev/md0?

So md1/md2 was NOT rebuilt?

Correct.

Well it should, after they are readded using -a.
If they still don't, then perhaps another resync is in progress.


There was nothing in progress, md0 was synced up and md1,md2 = degraded.
