The idea behind use exclusive volume activation mode with clvmd was(i think), have a vg active active and lvs opens just in one node, more lvm metadata replicated on all cluster nodes, when you'll do a change like lvm resize.
I have a redhat cluster with clvmd with vg active in exclusive mode, if you add pv to your volume group, every cluster node knows about the new pv in the vg, but anyway you cannot active the vg if it's active on other node, i think clvmd is needed just for replicate the lvm metadata 2013/12/2 Ulrich Windl <ulrich.wi...@rz.uni-regensburg.de> > >>> Lars Marowsky-Bree <l...@suse.com> schrieb am 29.11.2013 um 13:48 in > Nachricht > <20131129124833.gf22...@suse.de>: > > On 2013-11-29T13:46:17, Ulrich Windl <ulrich.wi...@rz.uni-regensburg.de> > wrote: > > > >> > I just did s/true/false/... > >> > > >> > Was that a clustered volume? > >> Clusterd && exclusive=true ?? > >> > >> No! > > > > Then it can't work.
