Hi, Can anyone please explain this to me: > # cat /proc/mdstat > > Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] > md2 : active raid5 sdf1[0] sde1[5] sdb1[6] sda1[3] sdd1[2] sdc1[4] > 4883799040 blocks super 1.1 level 5, 256k chunk, algorithm 2 > [6/6] [UUUUUU] Everything looks peachy, but: > # mdadm -E /dev/sda1 > [...] > Array Slot : 3 (0, failed, 2, 3, 1, 5, 4) > Array State : uuuUuu 1 failed Where does this 'failed' come from? Oh, and it's like that on all members. Is my array safe as /proc/mdstat says? See attached file for full info from mdadm -E for all the drives. -- Pozdrawiam Michał (Saviq) Sawicz
