Just be aware the warning could come back. You just moved the goal posts. The 1GB default is probably too low for most deployments, I have a PR to increase this: https://github.com/ceph/ceph/pull/32042 > Although I have to say that the message is IMHO *very* misleading: "1 > MDSs report oversized cache" sounds to me like the cache is too large > (i.e. wasting RAM unnecessarily). Shouldn't the message rather be "1 > MDSs report *undersized* cache"? Weird. No. I means the MDS cache is larger than its target. This means the MDS cannot trim its cache to go back under the limit. This could be for many reasons but probably due to clients not releasing capabilities, perhaps due to a bug. -- Patrick Donnelly, Ph.D. He / Him / His Senior Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
