Subject: mdadm: Failed to assemble all arrays
Package: mdadm
Version: 3.1.1-1+incremental+4
Severity: important
I was unable to boot starting November 27th 2009 due to bugs in grub2.
These are resolved in the meantime. However, I still cannot boot because of
mdadm.
Boot stops right after searching for root. It then sais: "failed to
assemble all arrays".
When booting with rootdelay=1 (or any other number >0) it drops in a shell
afterwards. Unfortunately, I did not manage to assemble the arrays.
Assembling all arrays after boot with Knoppix however works fine.
