Hi, I have tried to disabe filestore flusher filestore flusher = false filestore max sync interval = 30 filestore min sync interval = 29 in osd config. now, I see correct sync each 30s when doing rados bench rados -p pool3 bench 60 write -t 16 seekwatcher movie: before ------ http://odisoweb1.odiso.net/seqwrite-radosbench-flusherenable.mpg after ----- http://odisoweb1.odiso.net/seqwrite-radosbench-flusherdisable.mpg Shouldn't it be the normal behaviour ? What's exactly is filestore flusher vs syncfs ? This seem to works fine with rados bench, But when I launch benchmark with fio from my guest vm, I see again constant write. (I'll try to debug that today) My target is to be able to handle small random write and write them each 30s.
