Can someone tell me what this means please? I just received this in an email from one of my servers: From: mdadm monitoring [root@$DOMAIN.com] To: root@$DOMAIN.com Subject: FailSpare event on /dev/md2:$HOST.$DOMAIN.com This is an automatically generated mail message from mdadm running on $HOST.$DOMAIN.com A FailSpare event had been detected on md device /dev/md2. It could be related to component device /dev/sde2. Faithfully yours, etc. On this machine I execute: $ cat /proc/mdstat Personalities : [raid5] [raid4] [raid1] md0 : active raid1 sdf1[2](S) sde1[3](S) sdd1[4](S) sdc1[5](S) sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdf3[2](S) sde3[3](S) sdd3[4](S) sdc3[5](S) sdb3[1] sda3[0] 3068288 blocks [2/2] [UU] md2 : active raid5 sdf2[4] sde2[5](F) sdd2[3] sdc2[2] sdb2[1] sda2[0] 560732160 blocks level 5, 256k chunk, algorithm 2 [5/5] [UUUUU] unused devices: <none> Does the email message mean drive sde2[5] has failed? I know the sde2 refers to the second partition of /dev/sde. Here is the partition table # fdisk -l /dev/sde [root@elo ~]# fdisk -l /dev/sde Disk /dev/sde: 146.8 GB, 146815733760 bytes 255 heads, 63 sectors/track, 17849 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sde1 * 1 13 104391 fd Linux raid autodetect /dev/sde2 14 17465 140183190 fd Linux raid autodetect /dev/sde3 17466 17847 3068415 fd Linux raid autodetect I have partition 2 of drive sde as one of the raid devices for md. Does the (S) on sde3[2](S) mean the device is a spare for md1 and the same for md0?
