Public bug reported: Binary package hint: mdadm
hi. it's possible that i forgot once to "--set-faulty" before removing a device. i added a new drive, it rebuilded the md1, and started rebuilding md3 until around 40% then stops and i get the below data. i set-faulty /dev/sda3, remove failed, zero superblock, re-add the device and stil get the same. i also add a new device /dev/sdb3 and the same happens. i even grow the raid to 4 disks and try to add 2 disks at the same time - no succes. here is the data: dmesg shows this over and over [481073.717506] RAID1 conf printout: [481073.717509] --- wd:1 rd:2 [481073.717512] disk 0, wo:0, o:1, dev:sdc3 [481073.717514] disk 1, wo:1, o:1, dev:sda3 [481073.717515] RAID1 conf printout: [481073.717516] --- wd:1 rd:2 [481073.717518] disk 0, wo:0, o:1, dev:sdc3 [481073.717519] disk 1, wo:1, o:1, dev:sda3 [481074.099030] RAID1 conf printout: [481074.099034] --- wd:1 rd:2 [481074.099037] disk 0, wo:0, o:1, dev:sdc3 [481074.099039] disk 1, wo:1, o:1, dev:sda3 [481074.099040] RAID1 conf printout: [481074.099041] --- wd:1 rd:2 [481074.099043] disk 0, wo:0, o:1, dev:sdc3 [481074.099044] disk 1, wo:1, o:1, dev:sda3 dennis1 ~ $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md3 : active raid1 sda3[2] sdc3[0] 452550976 blocks [2/1] [U_] bitmap: 130/216 pages [520KB], 1024KB chunk md1 : active raid1 sda1[1] sdc1[0] 30716160 blocks [2/2] [UU] bitmap: 106/235 pages [424KB], 64KB chunk unused devices: <none> dennis1 ~ $ sudo mdadm --detail /dev/md3 /dev/md3: Version : 00.90 Creation Time : Wed Dec 22 05:55:45 2010 Raid Level : raid1 Array Size : 452550976 (431.59 GiB 463.41 GB) Used Dev Size : 452550976 (431.59 GiB 463.41 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 3 Persistence : Superblock is persistent Intent Bitmap : Internal Update Time : Thu Jan 6 23:57:07 2011 State : active, degraded Active Devices : 1 Working Devices : 2 Failed Devices : 0 Spare Devices : 1 UUID : 4c2769e4:568869bc:2a972c67:788b998b (local to host dennis1) Events : 0.726822 Number Major Minor RaidDevice State 0 8 35 0 active sync /dev/sdc3 2 8 3 1 spare rebuilding /dev/sda3 dennis1 ~ $ sudo mdadm /dev/sda3 --examine /dev/sda3: Magic : a92b4efc Version : 00.90.00 UUID : 4c2769e4:568869bc:2a972c67:788b998b (local to host dennis1) Creation Time : Wed Dec 22 05:55:45 2010 Raid Level : raid1 Used Dev Size : 452550976 (431.59 GiB 463.41 GB) Array Size : 452550976 (431.59 GiB 463.41 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 3 Update Time : Thu Jan 6 23:59:49 2011 State : clean Internal Bitmap : present Active Devices : 1 Working Devices : 2 Failed Devices : 1 Spare Devices : 1 Checksum : a4452cd8 -
