Hello,

I have the following problem with one of my raid1-arrays. One of the
drives has failed, but it isn't being marked as failed. The
reconstruction starts, and at 5% it borks out on the bad sectors. And
then it happily begins reconstructing again...
When I try to mark the drive as faulty, nothing happens. When I try to
hot-remove the drive, it complains about the drive being in use, because
it is reconstructing the array. When I try to start the array with only
one of the drives, it fails:

aeon root # mdadm --assemble /dev/md3 /dev/hde1
mdadm: /dev/md3 assembled from 0 drives - not enough to start it (use --run=
 to insist).
aeon root # mdadm --assemble --run /dev/md3 /dev/hde1
mdadm: failed to RUN_ARRAY /dev/md3: Invalid argument

And in the syslog, it says

May  4 18:26:02 [kernel] md: bind<hde1>
May  4 18:26:02 [kernel] raid1: no operational mirrors for md3

After the last command, in /proc/mdstat, it says

md3 : inactive hde1[2]
      120060736 blocks

and I can't do anything with it. When I do

aeon root # mdadm --manage --run /dev/md3
mdadm: failed to run array /dev/md3: Invalid argument
May  4 18:35:23 [kernel] md: bug in file drivers/md/md.c, line 1512

So, how do I tell the stupid thing to just run it in degraded mode, and
be happy with just one drive?

Any help would be greatly appreciated.

Regards,

Michel Wilson.
