Hello,
I stumbled upon a problem with xfs. It seems that it doesen't work with
software RAID1 the way I expected.
Attached are logs showing what I've done, and that it works with ext3, and
also dmesg.
Summary: One cannot use the same filesystem filtered through MD code and
without it ( filesystem is on /dev/sdaX, you can't mount it via /dev/md0,
or - filesystem was created on /dev/md0, you can't mount it via /dev/sdaX )
It hurts in two areas - one is that I'm trying to migrate existing system
into RAID1, I added another disk, partitioned it just like the first one,
expected to migrate nicely... I can't, although MD code seems to be doing
the right job.
Another is - when I've got RAID1-ed partition, I expect to be able to
mount both copies without using raid in emergencies.
That's the reason I'm using RAID1 and not 5.
Am I doing something wrong? Should xfs code be aware of software RAID
superblocks? Is MD code doing something wrong?
regards,
