Re: i made sh*t can anyone help!?

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

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.
