i have a problem with my md0 array, which is an raid1 (2 mirrored USB-Sticks)
Mount gives "Can't read superblock"
cat /proc/mdstat:
Personalities :
unused devices: <none>
fdisk -l
/dev/sdc1 2048 15679487 7838720 fd Linux raid autodetect
/dev/sdc1 2048 15679487 7838720 fd Linux raid autodetect
mdadm --assemble /dev/md0 /dev/sdb1 /dev/sdc1 gives:
mdadm: /dev/sdc1 misses out due to wrong homehost
mdadm: /dev/md0 has been started with 1 drive (out of 2).
and after several tries it seems to work with 1 drive now. How do I repair it without loss ? How do i fill /proc/mdstat if useful ?

I did a search for the "homehost" error and found http://askubuntu.com/questions/230525/raid-5-reassemble-stating-wrong-homehost . If you have one half of a mirror and want to construct a matching half, the "mdadm /dev/md0 -a /dev/sdc1" command should start a synchronization from /dev/sdb1 to /dev/sdc1.
