I have now discovered that /dev/md0 only consists of a single drive, /dev/sdc1, and /dev/sdb1 has been sitting idle, twiddling it's thumbs!
Argh!
I'd be grateful if someone could guide me through the process of reassembling the array, without losing/overwriting the new data on /dev/sdc1. I have read through man mdadm, but I'm not confident about my understanding. Or perhaps I could do it in Yast?
I'm not aware that yast can repair raids :-?
Here are my notes on mdadm (change device names as appropriate for your setup):
State of things:
mdadm --detail /dev/md0
This gives the following info: /dev/md0: Version : 01.00.03 Creation Time : Fri Jun 20 14:18:54 2008 Raid Level : raid1 Array Size : 976759864 (931.51 GiB 1000.20 GB) Used Dev Size : 1953519728 (1863.02 GiB 2000.40 GB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Persistence : Superblock is persistent Intent Bitmap : Internal Update Time : Thu Jan 1 12:26:29 2009 State : active, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : 0 UUID : 28fda9e6:9d4b3d1c:69069ea4:c79be70e Events : 99990 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 33 1 active sync /dev/sdc1 -- Registered Linux User #463880 FSFE Member #1300 GPG-FP: A6C1 457C 6DBA B13E 5524 F703 D12A FB79 926B 994E openSUSE 11.0, Kernel 2.6.25.18-0.2-default, KDE 3.5.10 Intel Celeron 2.53GHz, 2GB DDR RAM, nVidia GeForce 7600GS -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
