After rebooting, I saw this message scroll by duing shutdown: md4: no spare disk to reconstruct array! continuing in degraded mode ...so I restarted the system. After the system restarts, the array has the following status... %> cat /etc/raidtab ... raiddev /dev/md4 raid-level 1 nr-raid-disks 2 chuck-size 64k perrsistent-superblock 1 nr-spare-disks 0 device /dev/sda7 raid-disk 0 device /dev/sdb7 raid-disk 1 ... %> cat /proc/mdstat Personalities: [raid1] read_ahead 1024 sectors Event: 5 ... md4 : active raid1 sdb7[1] 50660864 blocks [2/1] [_U] So it would appear that sda7 has failed.
