hi guys i had a raid1 array, and i made shit, could i undo it? it have
filesystem with files :(
# mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb missing
mdadm: /dev/sdb appears to be part of a raid array:
level=raid1 devices=2 ctime=Wed Mar 16 19:01:50 2011
mdadm: Note: this array has metadata at the start and
may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90
Continue creating array?
Continue creating array? (y/n) y
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md0 started.

You had a RAID1 array? Of which devices did it consists of? Looks like
you only destroyed one.

only one :( the other was broken :(
it's xfs filesystem
mdadm --create /dev/md0 /dev/sdb
mkfs.xfs /dev/md0
mount /dev/md0 /home/
but since i made mdadm --create twice, it can't mount :(
# mount /dev/md0 /tmp2 -t xfs
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
