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
