Hi, 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 /debug/dlm/clvmd_locks. Is there a way to request dlm (via dlm_tool) to get the lock holding node or via any LVM command. Regards
Depending on the version you have dlm_tool will show you who holds the lock. But all it does is use the same debugfs interface you've already mentioned :-)
