Hi
I have three SATA 250 GB disks with two partitions on each one.
The first partition from each disk form a RAID1 array which is my root
partition. The second partition of each disk form a RAID5.
Everything was working fine, then I had to power off/on the machine as it
was hanging. At next boot the RAID1 array was degraded but running,
mdadm /dev/md0--add /dev/sdc2 fixed it.
The RAID5 array is still a problem, dmesg says:
md: created md1
md: bind<sda2>
md: bind<sdb2>
md: bind<sdc2>
md: running: <sdc2><sdb2><sda2>
md: kicking non-fresh sdc2 from array!
md: unbind<sdc2>
md: export_rdev(sdc2)
md: md1: raid array is not clean -- starting background reconstruction
raid5: device sdb2 operational as raid disk 0
raid5: device sda2 operational as raid disk 1
raid5: cannot start dirty degraded array for md1
RAID5 conf printout:
--- rd:3 wd:2 fd:1
disk 0, o:1, dev:sdb2
disk 1, o:1, dev:sda2
raid5: failed to run raid set md1
md: pers->run() failed ...
md: do_md_run() returned -5
md: md1 stopped.
md: unbind<sdb2>
md: export_rdev(sdb2)
md: unbind<sda2>
md: export_rdev(sda2)
mdadm --examine for those three partions:

Is there any way to recover?

Thanks for your time.
