Run backup of metadata on remote nodes in the same place like local node - when calling backup(). Introduce backup_locally() which calls only local backup if needed. Remote backup is now trigerred by LCK_VG_BACKUP flag combination (special VG lock). This lock type will call check_current_backup() (including backup_locally() call) and updates metadata on all nodes. (Patch fixes non-functional remote backup, current call during VG lock never triggers.)

* 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

|
|
* 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.
