[Bug 316670] Re: Raid10 array not assembled at boot, all disks are marked as spare

[lunomad]

Just adding my experience here, not sure if it is related.

I upgraded last night to the Jaunty Release Candidate.

Gdebi indicates that my installed mdadm is the same version as the AMD64
version from http://people.ubuntu.com/~kirkland/316670/

My root is on a regular sata disk, and I mount sdb1 and sdc1 as a Raid 1
mdadm+lvm2 (as /dev/md0 and /lvm/lvm-raid/homelv) on /home

The default upgrade did not find my md0, and instead puts sdc1 into a
false md_d0.

Every time I boot, I have to drop into a console, execute mdadm
--assemble --scan and manually mount the /dev/lvm-raid/homelv .  These
steps work, except my md0 is degraded to just one disk (sdb1)

I checked /proc/mdstat before the upgrade and everything was fine, so
I'm wondering if this is the same bug or a different one?

What's the best route to fix this?
