Hi Charles, I am more or less responding to your syslog issue. I don’t have the experience on cephfs to give you a reliable advice. So lets wait for the experts to reply. But I guess you have to give a little more background info, like This happened to running cluster, you didn’t apply any changes to? Looks like your dashboard issue is not related to "1 mgr finish mon failed to return metadata for mds.mds1" -----Original Message----- From: Charles Alva [mailto:charlesalva@xxxxxxxxx] Sent: vrijdag 20 april 2018 10:33 To: Marc Roos Cc: ceph-users Subject: Re: Ceph 12.2.4 MGR spams syslog with "mon failed to return metadata for mds" Hi Marc, I'm using CephFS and mgr could not get the metadata of the mds. I enabled the dashboard module and everytime I visit the ceph filesystem page, it got internal error 500.

Actually this is another argument to fix logging to syslog a bit, because the default syslog is also be set to throttle and group the messages like: Mar 9 17:59:35 db1 influxd: last message repeated 132 times https://www.mail-archive.com/ceph-users@xxxxxxxxxxxxxx/msg45025.htm l <https://www.mail-archive.com/ceph-users@xxxxxxxxxxxxxx/msg45025.html> -----Original Message----- From: Charles Alva [mailto:charlesalva@xxxxxxxxx] Sent: vrijdag 20 april 2018 8:08 To: ceph-users@xxxxxxxxxxxxxx Subject: Ceph 12.2.4 MGR spams syslog with "mon failed to return metadata for mds" Hi All, Just noticed on 2 Ceph Luminous 12.2.4 clusters, Ceph mgr spams the syslog with lots of "mon failed to return metadata for mds" every second. ``` 2018-04-20 06:06:03.951412 7fca238ff700 1 mgr send_beacon active 2018-04-20 06:06:04.934477 7fca14809700 0 ms_deliver_dispatch: unhandled message 0x55bf897f0a00 mgrreport(mds.mds1 +24-0 packed 214) v5 from mds.0 10.100.100.114:6800/4132681434 2018-04-20 06:06:04.934937 7fca25102700 1 mgr finish mon failed to return metadata for mds.mds1: (2) No such file or directory ``` How to fix this issue? or disable it completely to reduce disk IO and increase SSD life span?
