Hello after some trouble with disks, I am trying to reassemble an
array.  When I start the array, I am told I don't have enough disks to
start.  What is really strange to me is that when I examine the disks in
the array, mdadm gives me different overall information for different
disks.  What do I need to do to assemble the array?

**[root@server etc]# mdadm -As
**mdadm: /dev/md127 assembled from 3 drives - not enough to start the
array.**
*[root@server etc]# cat /proc/mdstat*
Personalities :
md127 : inactive sdf[2](S) sde[4](S) sdb[3](S) sdc[1](S) sdd[0](S)
      9767572480 blocks super 0.91

"--force" is your friend in such situations.

mdadm --stop /dev/md127
mdadm -Af /dev/md127 /dev/sd[bcdef]

You haven't given enough information for any advice on avoiding future
trouble...
