The command: mdadm --assemble /dev/md4
--uuid=d5c2d1f7:cf7cb245:2d9e7057:097ec133 /dev/sdc2
Results:
mdadm: /dev/md4 assembled from 0 drives and 1 spare - not enough to start
the array.
/proc/mdstat:
Personalities : [linear] [raid0] [raid1] [raid5]
read_ahead 1024 sectors
md4 : inactive sdc2[2]
0 blocks
The thing is that I have no spare-discs available in my system and
that "spare" disc _is_ the one that has always been the second mirror
of /dev/md4.
