Description Corey Marthaler 2007-11-30 11:01:44 EST
Description of problem:
Currently in clvm, a backup is made only on the node which does the operation.
Since this is a clustered volume manager, a back up should really be made on all
nodes incase the metadata gets corrupted and the volume needs to be restored.
One can currently work around this by creating the extra backups by hand.

Version-Release number of selected component (if applicable):
2.6.9-67.ELlargesmp
lvm2-2.02.27-4.el4
lvm2-cluster-2.02.27-4.el4
Comment 3 Christine Caulfield 2007-12-04 10:42:43 EST
I've added code to locking & clvmd so that when a clustered VG lock is removed,
the remote clvmds are told to take a metadata backup if the backups are out of
date. The remote copies will be tagged with a command of "clvmd" rather than the
lvm command that initiated the change.
