Did a "mdadm --re-add /dev/md2 /dev/sdf4", now it looks like: # mdadm -D /dev/md2 /dev/md2: Version : 00.91.03 Creation Time : Wed Oct 22 19:43:13 2008 Raid Level : raid5 Array Size : 2903386944 (2768.89 GiB 2973.07 GB) Used Dev Size : 967795648 (922.96 GiB 991.02 GB) Raid Devices : 6 Total Devices : 6 Preferred Minor : 2 Persistence : Superblock is persistent Update Time : Thu Mar 26 11:18:48 2009 State : clean, degraded, recovering Active Devices : 5 Working Devices : 6 Failed Devices : 0 Spare Devices : 1 Layout : left-symmetric Chunk Size : 64K Reshape Status : 14% complete Delta Devices : 2, (4->6) UUID : 2e27c42d:40936d45:53eb5abe:265a9668 Events : 0.96428 Number Major Minor RaidDevice State 0 8 4 0 active sync /dev/sda4 1 8 20 1 active sync /dev/sdb4 2 8 52 2 active sync /dev/sdd4 3 8 68 3 active sync /dev/sde4 4 0 0 4 removed 5 8 36 5 active sync /dev/sdc4 6 8 84 - spare /dev/sdf4 Looks very OK to me. *phew* I will wait until it isn't degraded anymore before I do the "pvresize".
