Looks like the "group_webservice" also needs a "globally_unique=false" attribute: Feb 15 18:10:15 wc01 crmd: [17757]: info: do_lrm_rsc_op: Performing key=134:44:0:9949f46a-b1a8-454e-a180-b7d746507937 op=fs_www:0_stop_0 ) Feb 15 18:10:15 wc01 lrmd: [17754]: info: rsc:fs_www:0: stop Feb 15 18:10:15 wc01 crmd: [17757]: info: do_lrm_rsc_op: Performing key=146:44:0:9949f46a-b1a8-454e-a180-b7d746507937 op=fs_www:1_stop_0 ) Feb 15 18:10:15 wc01 lrmd: [17754]: info: rsc:fs_www:1: stop ... the clones cannot be told apart, they seem to be running both on this node so they are both stopped ....
