In a clustered environment, without GFS, we plan to use CLVMD exclusive
activation of VG's in order to prevent a VG to be activated on more than 1
node at a time.
I've been looking for how to check who holds a lock for a given VG but I
could'nt find no suitable way to do it.
The only way was to activate debug ( mount -t debugfs debug /debug) and cat
Is there a way to request dlm (via dlm_tool) to get the lock holding node or
via any LVM command.
