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".
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
Personalities : [raid6] [raid5] [raid4] md127 : inactive sdf1 sdi1 sde1 sdj1 sdc1 sdg1 sdd1 sdn1 sdb1 sdm1 sda1 sdk1 860171694 blocks super 1.2 unused devices: <none>
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?
