I was trying to debug regression failures on [1] and observed that split-brain-resolution.t was failing consistently. ========================= TEST 45 (line 88): 0 get_pending_heal_count patchy ./tests/basic/afr/split-brain-</description>resolution.t .. 45/45 RESULT 45: 1 ./tests/basic/afr/split-brain- resolution.t .. Failed 17/45 subtests Test Summary Report ------------------- ./tests/basic/afr/split-brain- resolution.t (Wstat: 0 Tests: 45 Failed: 17) Failed tests: 24-26, 28-36, 41-45 On probing deeper, I observed a curious fact - on most of the failures stat was not served from md-cache, but instead was wound down to afr which failed stat with EIO as the file was in split brain. So, I did another test: * disabled md-cache * mount glusterfs with attribute-timeout 0 and entry-timeout 0 Now the test fails always. So, I think the test relied on stat requests being absorbed either by kernel attribute cache or md-cache. When its not happening stats are reaching afr and resulting in failures of cmds like getfattr etc. Thoughts?
