RE: fsck mdadm

Hello all,

Thanks to Javier and grant.
Yes I have think about that but :
cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md3 : active raid1 sda3[3] sdb3[2]
      958804544 blocks super 1.2 [2/2] [UU]

md1 : active raid1 sda1[3] sdb1[2]
      1048000 blocks super 1.2 [2/2] [UU]

md2 : active raid1 sda2[3] sdb2[2]
      16768896 blocks super 1.2 [2/2] [UU]

md5 : active raid5 sde1[9] sdd1[8] sdg1[5] sdf1[6] sdc1[7]
      15627542528 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/5] [UUUUU]

unused devices: <none>


(My problem is about MD5)

So, my five disks seem to be ok.

The following should give you some information on the health of your RAID array.

cat /proc/mdstat
