NOTE:
which data unsharing is occurring, the LVM configuration backup file might not always be in
sync with the LVM metadata on disk. LVM ensures that the configuration for volume group
Version 2.2 and higher is the latest by automatically backing it up during deactivation, unless
backup has been disabled by the -A n option. If the configuration backup during deactivation
will be bypassed, then to ensure that the volume group's configuration is the latest, it is
recommended that you close all the logical volumes of the volume group and back up the
configuration using vgcfgbackup prior to deactivating the volume group.
6. Update the boot structures after every change to the root volume group.
This task is only required if you are using LVM on your boot disk. Whenever you make changes
to the root volume group, which is usually named /dev/vg00, the BDRA on the boot disk
must be updated. This is normally performed automatically by the LVM commands. To update
the BDRA manually, enter the following command:
# /usr/sbin/lvlnboot -R

For volume group Version 2.2 and higher: volume groups that have snapshots on
for detailed information about recovery.
