after having problem to expand my array over 16TB, i need your help because my array dissapear suddenly....
I don't see anything in RAID management tab (it's all blank) and in the Files system tab my array is in missing status
i give you the result of a few command :
Code
root@Nargothrond:/# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : inactive sdc[0] sdg[6] sdb[3] sda[2] sdd[1]
