Hi, I have in one of my cluster a large omap object under luminous 12.2.8. HEALTH_WARN 1 large omap objects LARGE_OMAP_OBJECTS 1 large omap objects 1 large objects found in pool 'default.rgw.log' Search the cluster log for 'Large omap object found' for more details. In my setup the ha-proxy load balancer is running on 3 osd nodes which is monitor and manager also. When I look for this large omap object, this is the one: for i in `ceph pg ls-by-pool default.rgw.log | tail -n +2 | awk '{print $1}'`; do echo -n "$i: "; ceph pg $i query |grep num_large_omap_objects | head -1 | awk '{print $2}'; done | grep ": 1" 4.d: 1 I found only this way to reduce the size: radosgw-admin usage trim --end-date=2019-05-01 --yes-i-really-mean-it And I ran this many times like months by months. However when this is running the RGW became completely unreachable, the loadbalancer started to flapping and users started to complain because they can't do anything. Is there any other way to fix it, or any suggestion why this issue happens? Thank you. ________________________________ This message is confidential and is for the sole use of the intended recipient(s).
