Hi Dejan,

great, haven't even noticed there's 1.2.6 out..

however problem persists:

crm(live)configure# fencing_topology vbox4: stonith-vbox3-1-off,stonith-vbox3-2-off,stonith-vbox3-1-on,stonith-vbox3-2-on
ERROR: syntax: fencing_topology stonith-vbox3-1-off,stonith-vbox3-2-off,stonith-vbox3-1-on,stonith-vbox3-2-on

I've filled bug report as You requested:

cheers!
