I have a need to kick a disk out of a RAID 5 array. I can do a fdisk on 2 out of the 3 devices that form part of the array, so I suspect I know which one is bad. The problem is that mdstat shows the array as follows: md3 : active raid5 sda6[0] sdc6[2] sdb6[1] 960863488 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU] [>....................] resync = 0.7% (3444348/480431744) finish=582280.4min speed=1K/sec Doesn't this mean that all three disks are active and in use? mdadm -D /dev/md3 shows: Number Major Minor RaidDevice State 0 8 6 0 active sync /dev/sda6 1 8 22 1 active sync /dev/sdb6 2 8 38 2 active sync /dev/sdc6 So, my question is as follows: can I remove sdc6 and be sure the array will not stop? To make things worse, I see no disk failures in any log file. So I am not sure how sdc is actually failing.
