I have (second time) stuck mds warning: "Behind on trimming (63/30)". Looks working. What it mean and how to avoid it? And how to fix (exclude stop/migrate active mds)? Looks happened both time at night - probably on long backup/write operations (something like compressed local root backup to cephfs). Also all local mounts inside cluster (fuse) moved to automout to reduce clients pressure. Still 5 permanent kernel clients. Now I remount all but 1 kernel clients. Message persist. Current version 9.2.1-12-g3c10a09 with https://github.com/ceph/ceph/commit/24de350d936e5ed70835d0ab2ad6b0b4f506123f.patch , previous incident was older & without patch. -- WBR, Dzianis Kahanovich AKA Denis Kaganovich, http://mahatma.bspu.unibel.by/ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
