Greetings happy mdadm users.
I have a little problem that after many hours of searching around I
couldn't seem to solve.
I have upgraded my motherboard and kernel (bad practice I know but the
ICH9R controller needs 2.6.2*+) at the same time.
The array was build using 2.6.18-7 Now i'm using 2.6.21-2
I'm trying to recreate the raid array with the following command and
this is the error I get:
mca4:~# mdadm -Av /dev/md1 /dev/sdb /dev/sdc /dev/sdd /dev/sde
/dev/sdf /dev/sdg
mdadm: looking for devices for /dev/md1
mdadm: no RAID superblock on /dev/sdc
mdadm: /dev/sdc has no superblock - assembly aborted
So I figure, oh look the disk sdc has gone cactus, I'll just remove it
from the list. One of the advantages of mdadm.
mca4:~# mdadm -Av /dev/md1 /dev/sdb /dev/sdd /dev/sde /dev/sdf /dev/sdg
mdadm: looking for devices for /dev/md1
mdadm: /dev/sdb is identified as a member of /dev/md1, slot -1.
mdadm: /dev/sdd is identified as a member of /dev/md1, slot 0.
mdadm: /dev/sde is identified as a member of /dev/md1, slot 1.
mdadm: /dev/sdf is identified as a member of /dev/md1, slot 5.
mdadm: /dev/sdg is identified as a member of /dev/md1, slot 4.
mdadm: added /dev/sde to /dev/md1 as 1
mdadm: no uptodate device for slot 2 of /dev/md1
mdadm: no uptodate device for slot 3 of /dev/md1
mdadm: added /dev/sdg to /dev/md1 as 4
mdadm: added /dev/sdf to /dev/md1 as 5
mdadm: failed to add /dev/sdb to /dev/md1: Invalid argument
mdadm: added /dev/sdd to /dev/md1 as 0
mdadm: /dev/md1 assembled from 4 drives - not enough to start the array.
If found this really difficult to understand considering that I can
get the output of mdamd -E /dev/sdb (other disks included to overload
you with information)
mdadm -E /dev/sd[b-h]

So I decided to try rebuilding the array with the UUID, perhaps that will work.

Now, when the raid array was working all the disks contained the
correct information, now two disks are not functioning. I'd believe
one failed disk during the upgrade process but two having issues is
perplexing.
If anyone could offer a solution I'd be forever grateful, also to
prove that supporting open source isn't all free labour I'll send you
can choose one of 1 of 2 Nintendo DS games, the new radiohead album or
a cree flash light. :)

You're trying to assemble the array from 6 disks here and one looks to
be dodgy. That's okay so far.

Now you're trying to assemble with 5 disks and getting 4 out of 6 in the
array, and one at slot -1 (i.e. a spare).

And here we see that the array has 6 active devices and a spare. You
currently have 4 working active devices, a failed active device and the
spare. What's happened to the other device? You can't get the array
working with 4 out of 6 devices so you'll need to either find the other
active device (and rebuild onto the spare) or get the failed disk
working again.
HTH,
Robin

Hey, this looks similar to what I recently had.
(http://www.mail-archive.com/linux-raid@vger.kernel.org/msg09306.html)
I my case a RAID5 reshape was interrupted and the new devices were
also marked spare with slot -1.
Apply the attached patch to mdadm-2.6.3, build then do:
mdadm -S /dev/md1
./mdadm -Av /dev/md1 --update=this /dev/sd[b-g]
That should update the slot on /dev/sdb. Then:
mdadm -S /dev/md1
./mdadm -Av /dev/md1 /dev/sd[bcdefg]
should bring back your array in degraded mode.
If it works send your gifts to Neil Brown <neilb@suse.de>, he wrote
the patch! :)
Good luck!
