LVM partition "Not available"?

  • 772

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?

linux lvm

    Do you get any luck with:

    lvchange -a y /dev/xen-disk/xen1-disk

    ?
