|
This started after a lightning storm with several power outages:
I have a 3 disk software RAID 5 (md0: hdb1, hdc1, hdd1) running with mdadm. Besides that there are 3 more RAID 1 (md1-md3 on hda & hde). After the power outages the RAID 5 doesn't start up on boot. dmesg gives me this:
| Code: | md: raid1 personality registered as nr 3
md: md driver 0.90.1 MAX_MD_DEVS=256, MD_SB_DISKS=27

After booting it is no problem to start the array manually by using
| Code: | server ~ # mdadm --assemble /dev/md0 /dev/hdb1 /dev/hdc1 /dev/hdd1
mdadm: /dev/md0 has been started with 3 drives. |
dmesg gives me on that:
| Code: | md: md0 stopped.
md: md0 stopped.
md: bind<hdd1>
md: bind<hdc1>
md: bind<hdb1>
raid5: device hdb1 operational as raid disk 0
raid5: device hdc1 operational as raid disk 2
raid5: device hdd1 operational as raid disk 1
raid5: allocated 3154kB for md0
raid5: raid level 5 set md0 active with 3 out of 3 devices, algorithm 2
RAID5 conf printout:
--- rd:3 wd:3 fd:0
disk 0, o:1, dev:hdb1
disk 1, o:1, dev:hdd1
disk 2, o:1, dev:hdc1 |
After that the array works just fine...
Any ideas?
