Hi all, I have a ceph cluster(12.2.5), all servers run on centos7.
Recently I noticed some error log in mgr
2019-02-28 12:02:16.302888 7ff5665ff700 0 ms_deliver_dispatch: unhandled message 0x7ff5913539c0 mgrreport(mds.ceph04 +24-0 packed 214) v5 from mds.0 x.x.x.x:6800/3089687518
2019-02-28 12:02:16.303352 7ff56f683700 1 mgr finish mon failed to return metadata for mds.ceph04: (2) No such file or directory
I found this mail http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-April/026114.html. Seems that someone also hits the problem.
How to fix it, any suggestion? Thanks a lot.
