replay-dual is failing with "FAIL: test_10 failed with 1". Results are at https://testing.hpdd.intel.com/test_sessions/fff27cc4-addd-11e4-a0b6-5254006e85c2 .

From the client's test log:

What's actually failing is the mcreate in the replay_barrier() function:

replay_barrier() {
        local facet=$1
        do_facet $facet "sync; sync; sync"
	df $MOUNT

        # make sure there will be no seq change                                 
        local clients=${CLIENTS:-$HOSTNAME}
        local f=fsa-\\\$\(hostname\)
        do_nodes $clients "mcreate $MOUNT/$f; rm $MOUNT/$f"
        do_nodes $clients "if [ -d $MOUNT2 ]; then mcreate $MOUNT2/$f; rm $MOUNT2/$f; fi"

Every test session I've checked, about 10, every time test 10 fails with this error, it is preceded by a test 9 failure 'post-failover df: 1' ~~LU-6057~~. Maybe when test 9 fails, it does not clean up.

Test 10 has failed intermittently with the "mcreate: cannot create * with mode 0100644: File exists" error since December 2014.
