I have a disk that I took out of a failed system. One of the partitions on the disk was one half of a software RAID-1, and that RAID-1 was a lvm2 volume group. There are several logical volumes on that volume group. Thanks to this answer I got the RAID-1 mounted and the volume group seen and recognized. I can mount most of the partitions and back them up, but one of them (of course the one I care about the most) won't mount. The system crashed while I had a snapshot partition snapshotting this partition for a backup, but I've now removed that snapshot. lvdisplay reports:
lvdisplay -v /dev/xen-disk/xen1-disk Using logical volume(s) on command line --- Logical volume --- LV Name /dev/xen-disk/xen1-disk VG Name xen-disk LV UUID li3NC9-jRwg-ndbM-oplJ-1Omd-PcX9-qv9aB2 LV Write Access read/write LV Status NOT available LV Size 150.00 GB Current LE 38400 Segments 1 Allocation inherit Read ahead sectors 0
How do I repair whatever is making this unavailable and get it mounted?
