Subject: Raid5 regression
Date: Tue, 03 May 2011 10:33:46 -0400	[thread overview]
Message-ID: <4DC0124A.7010508@cfl.rr.com> (raw)

After upgrading an Ubuntu server from Maverick to Natty ( grub2 version 
1.99-rc1-13ubuntu3 ) the system no longer will boot.  Grub complains 
about the raid5 array:

error: Found two disks with the index 0 for RAID md0
error: Found two disks with the index 1 for RAID md0
error: Found two disks with the index 2 for RAID md0
error: Superfluous RAID member (4 found)
error: Unknown filesystem

This is a 4 disk raid5 array that mdadm still recognizes and looks fine, 
with each disk having IDs 0 through 3 respectively. Despite the fact 
that it complains about the raid, it still shows the LVM logical volumes 
in the output of ls. The array is the sole LVM PV.

Bug filed at https://launchpad.net/bugs/776422.  Any hints on how to 
proceed with debugging this?  Is there a way to check what modules are 
built into the core image from the rescue shell?
