I am using LVM on a software raid 1 disk and tried to use pvmove. It got an IO error and crashed at 62%. When I rebooted the box and tried to restart pvmove it said that the number of segments doesn't match the metadata. Now the logical volumes report an IO error when I try to mount any of them. The logical volumes have XFS file systems on them and the data we are trying to recover are the innodb files from mysql This has really important data that we failed to backup. Does anyone have any ideas about how to fix pvmove or find the innodb files on the raw disk? -Jordan Curzon /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
Jordan, There is a backup of your lvm in /etc/lvm/backup (hopefully). It should help you identify what problems might exist. Also, I found a very helpful tutorial over at Linux Journal a while back when I destroyed my LVM. My recovery was fairly successful, I hope yours will be too. Here's the links: http://fedora-tutorials.com/2006/09/15/lvm-from-failure-to-recovery/ - My crashed LVM story http://www.linuxjournal.com/article/8874 - A very useful LJ article.
