Hi Paul, Nigel, I'm also seeing "HEALTH_WARN 6 large omap objects" warnings with cephfs after upgrading to 14.2.4: The affected osd's are used (only) by the metadata pool: POOL ID STORED OBJECTS USED %USED MAX AVAIL mds_ssd 1 64 GiB 1.74M 65 GiB 4.47 466 GiB See below for more log details. While I'm glad we can silence the warning, should I be worried about the values reported in the log causing real problems? many thanks Jake [root@ceph1 ~]# zgrep "Large omap object found" /var/log/ceph/ceph.log* /log/ceph/ceph.log-20191022.gz:2019-10-21 15:43:45.800608 osd.2 (osd.2) 262 : cluster [WRN] Large omap object found.
