Hello I did remove sdq1 from my 6-device autodetecting kernel 2.2.11-raid5-set. Now there's no way, to bring it back. 'No spare-disk' it says. What do I need to do? I tried to rearange the sequenze in /etc/raidtab (device 0 to the bottom) I added a spare-disk in raidtab. Please see the boot-messages at the bottom. Thanks Urs -------------------------------------------- running: <sdr1><sdq1><sdp1><sdl1><sdk1><sdj1> now! sdr1's event counter: 0000001a sdq1's event counter: 00000008 sdp1's event counter: 0000001a sdl1's event counter: 0000001a sdk1's event counter: 0000001a sdj1's event counter: 0000001a md: superblock update time inconsistency -- using the most recent one freshest: sdr1 md: kicking non-fresh sdq1 from array! unbind<sdq1,5> export_rdev(sdq1) md0: max total readahead window set to 640k md0: 5 data-disks, max readahead per data-disk: 128k raid5: device sdr1 operational as raid disk 1 raid5: device sdp1 operational as raid disk 5 raid5: device sdl1 operational as raid disk 0 raid5: device sdk1 operational as raid disk 2 raid5: device sdj1 operational as raid disk 4 raid5: md0, not all disks are operational -- trying to recover array raid5: allocated 6350kB for md0 raid5: raid level 5 set md0 active with 5 out of 6 devices, algorithm 2 RAID5 conf printout: --- rd:6 wd:5 fd:1 disk 0, s:0, o:1, n:0 rd:0 us:1 dev:sdl1 disk 1, s:0, o:1, n:1 rd:1 us:1 dev:sdr1 disk 2, s:0, o:1, n:2 rd:2 us:1 dev:sdk1 disk 3, s:0, o:0, n:3 rd:3 us:1 dev:[dev 00:00] disk 4, s:0, o:1, n:4 rd:4 us:1 dev:sdj1 disk 5, s:0, o:1, n:5 rd:5 us:1 dev:sdp1 disk 6, s:0, o:0, n:0 rd:0 us:0 dev:[dev 00:00] disk 7, s:0, o:0, n:0 rd:0 us:0 dev:[dev 00:00] .... disk 11, s:0, o:0, n:0 rd:0 us:0 dev:[dev 00:00] md: updating md0 RAID superblock on device sdr1 [events: 0000001b](write) sdr1's sb offset: 2048192 md: recovery thread got woken up ... md0: no spare disk to reconstruct array! -- continuing in degraded mode md: recovery thread finished ... sdp1 [events: 0000001b](write) sdp1's sb offset: 2048192 sdl1 [events: 0000001b](write) sdl1's sb offset: 2048192 sdk1 [events: 0000001b](write) sdk1's sb offset: 2048192 sdj1 [events: 0000001b](write) sdj1's sb offset: 2048192 . ... autorun DONE. ------------------ This is raidtab -------------------------------------- raiddev /dev/md0 raid-level 5 nr-raid-disks 6 persistent-superblock 1 chunk-size 32 parity-algorithm left-symmetric # only added later, after building raidset! nr-spare-disks 1 device /dev/sdo1 spare-disk 0 device /dev/sdr1 raid-disk 1 device /dev/sdk1 raid-disk 2 device /dev/sdq1 raid-disk 3 device /dev/sdj1 raid-disk 4 device /dev/sdp1 raid-disk 5 device /dev/sdl1 raid-disk 0
