Bug Description

Binary package hint: mdadm

Note that this server was originally setup with 6.06, upgraded to 6.10, and just now upgraded to Feisty.

UUID of the new mdadm.conf does not match the UUID in etc/fstab.

One is for the RAID-array and the other for the filesystem. Those are not supposed to be equal.

OK. I didn't see your comment before I posted the last one.

I changed the UUID in mdadm.conf from 86d9233e:76b2ecb1:017aa5e1:eabe42ad to a70c88cf-546d-479b-812f-bf2309f5dc1b and the system booted. Are you saying I should change the UUID in mdam.conf back to the automatically generated one?

I looked in /dev/disk/by-uuid and did not find that UUID listed.
