5.3.13. Backing Up Volume Group Metadata
Metadata backups and archives are automatically created on every volume group and logical volume configuration change unless disabled in the
lvm.conf
file. By default, the metadata backup is stored in the /etc/lvm/backup
file and the metadata archives are stored in the /etc/lvm/archives
file. You can manually back up the metadata to the /etc/lvm/backup
file with the vgcfgbackup
command.
The
vgcfrestore
command restores the metadata of a volume group from the archive to all the physical volumes in the volume groups.
For an example of using the
vgcfgrestore
command to recover physical volume metadata, see Section 7.4, “Recovering Physical Volume Metadata”.
