Hi,

some more information about the cluster status would be helpful, such as

ceph -s
ceph osd tree

service status of all MONs, MDSs, MGRs.
Are all services up? Did you configure the spare MDS as standby for rank 0 so that a failover can happen?

Regards,
Eugen


Zitat von dhils...@performair.com:

All;

I built a demonstration and testing cluster, just 3 hosts (10.0.200.110, 111, 112). Each host runs mon, mgr, osd, mds.

During the demonstration yesterday, I pulled the power on one of the hosts.

After bringing the host back up, I'm getting several error messages every second or so: 2019-06-26 16:01:56.424 7fcbe0af9700 0 ms_deliver_dispatch: unhandled message 0x55e80a728f00 mgrreport(mds.S700030 +0-0 packed 6) v7 from mds.? v2:10.0.200.112:6808/980053124 2019-06-26 16:01:56.425 7fcbf4cd1700 1 mgr finish mon failed to return metadata for mds.S700030: (2) No such file or directory 2019-06-26 16:01:56.429 7fcbe0af9700 0 ms_deliver_dispatch: unhandled message 0x55e809f8e600 mgrreport(mds.S700029 +110-0 packed 1366) v7 from mds.0 v2:10.0.200.111:6808/2726495738 2019-06-26 16:01:56.430 7fcbf4cd1700 1 mgr finish mon failed to return metadata for mds.S700029: (2) No such file or directory

Thoughts?
