In my tethology test rgw/multisite,tasks is three-zone test. I find test_datalog_autotrim is failed.

I take a moment to look at the test cases. I find test_datalog_autotrim, that does not guarantee that all zones are trimmed.Maybe we should check twice.
In my photo. We find taht zonegroup_data_checkpoint maybe stop in t4-stage.Because zonegroup_data_checkpoint check Bdataloglatest and Cdataloglatest is sync over in t2 stage. In fact they end at stage 5.
If zonegroup_data_checkpoint return in t4-stage and datalog trim occurs before stage 5. Bdatalog and Cdatalog will not trim.
