Dear all,

I have a 12 x 500Gb RAID-5 hardware RAID array on an ARECA 1130-ML
controller. There is one single partition on it, exported as /dev/sdc1.
This configuration used to work fine for 4 months.
Then the computer crashed a couple of times, and led to a situation where

xfs_check /dev/sdc1 output is:

xfs_check: unexpected XFS SB magic number 0x45464920

That spells "EFI"

looks like somebody came along & labeled your disk for you. Dangers of being on a san I suppose (if you are....)

repair might fix it....
