I'd recommend to make sure that:
1. clvmd runs in 'corosync' mode, not 'openais' (controlled by -I
command-line switch), because otherwise it uses buggy LCK AIS service
instead of well tested CPG+DLM,
2. You have recent enough version of lvm2. 2.02.102 should be ok, you
need git commit 431eda6
(https://git.fedorahosted.org/cgit/lvm2.git/commit/?id=431eda63cc0ebff7c62dacb313cabcffbda6573a),
introduced somewhere between 2.02.99 and 2.02.102.

I didn't test that commit with corosync-1, but that should work for it.

Hope this helps,
