I have a Supermicro machine running on centos 5.3 with 3ware 9650SE controller.
I run Software RAID 1 for sda and sdb to host / /root and swap. no error
I configured the remaining hdd (14) to run RAID 6 with spare. RAID 6 and spare was created according to my requirement but once reboot the entire RAID is gone. Also i notice the following message when booting the system
Invalid RAID Superblock Magic sdc1 all the way till sdp1
Any idea how to fix the problem ?
