degraded raid 5 problem
I have a strange problem. I've got two raid volumes, md0 and md1, on three physical disks. md0 is raid-0 with three mirrors; this volume comes up just fine. md1 is raid-5. The other day after powering up the server after some routine maintenance (which did not involve the disks or cabling) I note thatdev-md1 is running in degraded mode. Here'sproc-mdstat:
Personalities : raid1 raid5 readahead 1024 sectors md0 : active raid1 sdc12 sdb11 sda10 104320 blocks 3-3 UUU
md1 : active raid5 sdb21 sda20 35342848 blocks level 5, 64k chunk, algorithm 0 3-2 UU
And myetc-raidtab:
raiddev dev-md1 raid-level 5 nr-raid-disks 3 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device dev-sda2 raid-disk 0 device dev-sdb2 raid-disk 1 device dev-sdc2 raid-disk 2 raiddev dev-md0 raid-level 1 nr-raid-disks 3 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device dev-sda1 raid-disk 0 device dev-sdb1 raid-disk 1 device dev-sdc1 raid-disk 2
As you can see, sdc2 is part of the raid-5 array which is offline while sdc1 is part of the raid-0 array and is listed as online. ???
Anybody know what might cause this and an easy way to fix?
thx
