I have a degraded raid array (originally raid-10, now only two drives) that contains an LVM volume. I can see in the appended text that the Xen domains are there but I don't see how to mount them. No doubt this is just ignorance on my part but I wonder if anyone would care to direct me? I want to be able to retrieve dom-0 and one of the dom-Us to do data recovery, the others are of no interest.

Suggestions? Will rtfm if directed.

Please try to mount */dev/VolGroup00/oldserver *not */dev/mapper/dev/VolGroup00/LogVol00/bulkley *because in your *lvscan* result was showing /dev/VolGroup00/oldserver .

Then share the result.
