Bootet today, got this in dmesg: [ 44.884915] md: bind<sdd1> [ 44.885150] md: bind<sda1> [ 44.885352] md: bind<sdb1> [ 44.885552] md: bind<sdc1> [ 44.885601] md: kicking non-fresh sdd1 from array! [ 44.885637] md: unbind<sdd1> [ 44.885671] md: export_rdev(sdd1) [ 44.900824] raid5: device sdc1 operational as raid disk 1 [ 44.900860] raid5: device sdb1 operational as raid disk 3 [ 44.900895] raid5: device sda1 operational as raid disk 2 [ 44.901207] raid5: allocated 4203kB for md0 [ 44.901241] raid5: raid level 5 set md0 active with 3 out of 4 devices, algorithm 2 [ 44.901284] RAID5 conf printout: [ 44.901317] --- rd:4 wd:3 [ 44.901349] disk 1, o:1, dev:sdc1 [ 44.901381] disk 2, o:1, dev:sda1 [ 44.901414] disk 3, o:1, dev:sdb1 Checked the disk, seemed fine (not the first time linux kicked a disk for no apparent reason), readded it with mdadm which triggered a resync. Now having a look at it I get: $ cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md0 : active raid5 sdd[4] sdc1[1] sdb1[3] sda1[2] 732563712 blocks level 5, 32k chunk, algorithm 2 [4/3] [_UUU] [=>...................] recovery = 8.1% (19867520/244187904) finish=1661.6min speed=2248K/sec 1661 minutes is *way* too long. it's a 4x250GiB sATA array and usually takes 3 hours to resync or check, for that matter.
