Hello, when I run: while true; do ~/tests/xfstests-dev/ltp/fsstress -d /mnt -n 10000 -p 4; done and in parallel while true; do ./fsfreeze /mnt; sync; ./fsfreeze -u /mnt; sleep 3; done where fsfreeze is a small utility freezing and unfreezing filesystem. I get warnings like: [ 2029.103193] XFS (vdb1): xlog_space_left: head behind tail [ 2029.103195] tail_cycle = 10, tail_bytes = 6036480 [ 2029.103197] GH cycle = 10, GH bytes = 6035728 [ 2029.103218] XFS (vdb1): xlog_space_left: head behind tail [ 2029.103219] tail_cycle = 10, tail_bytes = 6036480 [ 2029.103220] GH cycle = 10, GH bytes = 6035728 [ 2033.269796] XFS (vdb1): xlog_space_left: head behind tail [ 2033.269800] tail_cycle = 10, tail_bytes = 6400512 [ 2033.269803] GH cycle = 10, GH bytes = 6399752 [ 2033.269830] XFS (vdb1): xlog_space_left: head behind tail [ 2033.269835] tail_cycle = 10, tail_bytes = 6400512 [ 2033.269838] GH cycle = 10, GH bytes = 6399752 [ 2033.269847] XFS (vdb1): xlog_space_left: head behind tail [ 2033.269850] tail_cycle = 10, tail_bytes = 6400512 [ 2033.269852] GH cycle = 10, GH bytes = 6399752 [ 2033.269892] XFS (vdb1): xlog_space_left: head behind tail [ 2033.269894] tail_cycle = 10, tail_bytes = 6400512 [ 2033.269896] GH cycle = 10, GH bytes = 6399752 [ 2033.269915] XFS (vdb1): xlog_space_left: head behind tail [ 2033.269918] tail_cycle = 10, tail_bytes = 6400512 [ 2033.269920] GH cycle = 10, GH bytes = 6399752 They usually start to appear like 20 minutes after starting the tests and when they start to appear they happen every couple of seconds (as you can see from the timestamps). Is it a real problem or just annoyance?
