description |
I tried to upgrade a server, and i was left with a broken grub2. I think it has to do something with LVM/RAID.
My setup: /root lies on LVM which is on a Raid5. There's not separate boot partition.
When i reinstall grub2 from the command-line i get the following errors:
...

When using mdadm metadata format 0.9 and the partition is at the end of the disk, grub can not tell whether it is the partition or the whole disk that is the raid component, resulting in errors like:
error: found two disks with the index 0 for RAID md0.
error: found two disks with the index 3 for RAID md0.
error: superfluous RAID member (4 found).
error: superfluous RAID member (4 found).
error: superfluous RAID member (4 found).
This can cause unexpected failure after upgrading from 10.04. |
