Hi, I'm still trying to find why there is much more write operations on filestore since Emperor/Firefly than from Dumpling. So, I add monitoring of all perf counters values from OSD. >From what I see : «filestore.ops» reports an average of 78 operations per seconds. But, block device monitoring reports an average of 113 operations per seconds (+45%). please thoses 2 graphs : - https://daevel.fr/img/firefly/osd-70.filestore-ops.png - https://daevel.fr/img/firefly/osd-70.sda-ops.png Do you see what can explain this difference ? (this OSD use XFS) Thanks, Olivier _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
