Re: [Linux-HA] Antw: Re: SLES11 SP2 HAE: problematic change for LVM RA
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. Exclusive activation only works for clustered volume groups, since it uses the DLM to protect against the VG being activated more than once in the cluster. Hi! Try it with resource-agents-3.9.4-0.26.84: it works; with resource-agents-3.9.5-0.6.26.11 it doesn't work ;-) You could argue that it never should have worked. Anyway: If you want to activate a VG on exactly one node you should not need cLVM; only if you man to activate the VG on multiple nodes (as for a cluster file system)...
