Hi,
what is the output of 'cat /proc/mdstat' ?
A healthy raid should look something like below :
[root at janeway ~]# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sdb1[0] sda1[1]
256896 blocks [2/2] [UU]
md0 : active raid1 sdd1[0] sdc1[1]
1465135936 blocks [2/2] [UU]
md3 : active raid1 sdb3[1] sda3[0]
730218432 blocks [2/2] [UU]
I have 3 RAID1 arrays (over 4 disks)
