I have a RAID 5 array (with LVM on top) on a CentOS 6 box. The array itself is an LSI StorageTek disk shelf with 14 drives connected to the server with a fibre channel cable.
After rebooting the machine the RAID array won't come back up. Disk Utility in Gnome states that it is "Not running, partially assembled".
I ran mdadmin --assemble --scan
, which said:
mdadm: /dev/md/:storagetek-1_0 assembled from 1 drive - not enough to start the array.
mdadm: No arrays found in config file or automatically
/proc/mdstat says:
Personalities : [raid6] [raid5] [raid4]
md127 : inactive sdf1[7] sdi1[4] sde1[8] sdj1[3] sdc1[10] sdg1[6] sdd1[9] sdn1[12] sdb1[11] sdm1[0] sda1[14] sdk1[2]
860171694 blocks super 1.2

I'm pretty new to managing RAID arrays on Linux (could you guess?) so I've reached the limit of my very limited knowledge on the subject.
I'm optimistically hoping that it's in the process of being rebuilt, but from what I've seen I doubt it.
Please can somebody give me a hint on how to fix it?
