Previously, vgcfgrestore would attempt to vg_remove the existing VG from lvmetad and then vg_update to add the restored VG. But, if there was a failure in the command or with vg_update, the lvmetad cache would be left incorrect. Now, disable lvmetad before the restore begins, and then rescan to populate lvmetad from disk after restore has written the new VG to disk.

/*

* There are two operations that come under the general area of
|
|
* backups. 'Archiving' occurs just before a volume group
|
|
* configuration is changed. The user may configure when
|
|
* archived files are expired. Typically archives will be stored
|
|
* in /etc/lvm/archive.
|
|
*
|
|
* A 'backup' is a redundant copy of the *current* volume group
|
|
* configuration. As such it should be taken just after the
|
|
* volume group is changed. Only 1 backup file will exist.
|
|
* Typically backups will be stored in /etc/lvm/backups.
