local clients=${CLIENTS:-$HOSTNAME}
do_nodes $clients "f=${MOUNT}/fsa-\\\$(hostname); mcreate \\\$f; rm \\\$f"
local svc=${facet}_svc
do_facet $facet $LCTL --device %${!svc} notransno

}
"sync sync sync" should be moved after the mcreate, so all of the ops should be committed before the barrier, otherwise mcreate might be replayed as well, which sometimes confuse the test results.
