There's also good information in the /etc/lvm/backup directory. Each time you do a major operation (pvcreate, vgcreate, etc), the LVM tools update a flat text file in /etc/lvm/backup representing the metadata. This is the same metadata that's saved to the front of every PV. Some commands (like pvcreate) can use this text file to restore the metadata if it's ever lost.
If you're backing up the entire disk, in most cases this is irrelevant (because it's stored on the disk anyway), but this could be useful for keeping backups of just the metadata in data recovery situations, where depending on the situation you may not want to restore the full volume. -Brad On Tue, 2008-04-08 at 12:39 -0400, Romanowski, John (OFT) wrote: > What linux distribution are you running? > Our SLES 9 & 10 linux guests run 24x365 and can't be down for an image > backup. > We're using Tivoli Storage Manager (TSM) for daily incremental file > level backups over a network. > > "BMRtool scan" run daily, before the TSM backups, captures the latest > partition, LVM and filesystem metadata to files so that's on the TSM > backup. > > The scan also generates a custom file of commands your rescue system > would run to load disk device drivers, bring the disks online, dasdfmt > 'em, partition-em, LVM-them, fs-em, mount-em, chmod-em, chown-em, and > the TSM restore commands to restore-em.
