Hi all, I’m still new to ceph and cephfs. Trying out the multi-fs configuration on at Luminous test cluster. I shutdown the cluster to do an upgrade and when I brought the cluster back up I now have a warnings that one of the file systems has
a failed mds daemon: 2017-08-21 17:00:00.000081 mon.carf-ceph-osd15 [WRN] overall HEALTH_WARN 1 filesystem is degraded; 1 filesystem is have a failed mds daemon; 1 pools have many more objects per pg than average; application not enabled on 9 pool(s) I tried restarting the mds service on the system and it doesn’t seem to indicate any problems: 2017-08-21 16:13:40.979449 7fffed8b0700 1 mds.0.20 shutdown: shutting down rank 0 2017-08-21 16:13:41.012167 7ffff7fde1c0 0 set uid:gid to 167:167 (ceph:ceph) 2017-08-21 16:13:41.012180 7ffff7fde1c0 0 ceph version 12.1.4 (a5f84b37668fc8e03165aaf5cbb380c78e4deba4) luminous (rc), process (unknown), pid 16656 2017-08-21 16:13:41.014105 7ffff7fde1c0 0 pidfile_write: ignore empty --pid-file 2017-08-21 16:13:45.541442 7ffff10b7700 1 mds.0.23 handle_mds_map i am now mds.0.23 2017-08-21 16:13:45.541449 7ffff10b7700 1 mds.0.23 handle_mds_map state change up:boot --> up:replay 2017-08-21 16:13:45.541459 7ffff10b7700 1 mds.0.23 replay_start 2017-08-21 16:13:45.541466 7ffff10b7700 1 mds.0.23 recovery set is 2017-08-21 16:13:45.541475 7ffff10b7700 1 mds.0.23 waiting for osdmap 1198 (which blacklists prior instance) 2017-08-21 16:13:45.565779 7fffea8aa700 0 mds.0.cache creating system inode with ino:0x100 2017-08-21 16:13:45.565920 7fffea8aa700 0 mds.0.cache creating system inode with ino:0x1 2017-08-21 16:13:45.571747 7fffe98a8700 1 mds.0.23 replay_done 2017-08-21 16:13:45.571751 7fffe98a8700 1 mds.0.23 making mds journal writeable 2017-08-21 16:13:46.542148 7ffff10b7700 1 mds.0.23 handle_mds_map i am now mds.0.23 2017-08-21 16:13:46.542149 7ffff10b7700 1 mds.0.23 handle_mds_map state change up:replay --> up:reconnect 2017-08-21 16:13:46.542158 7ffff10b7700 1 mds.0.23 reconnect_start 2017-08-21 16:13:46.542161 7ffff10b7700 1 mds.0.23 reopen_log 2017-08-21 16:13:46.542171 7ffff10b7700 1 mds.0.23 reconnect_done 2017-08-21 16:13:47.543612 7ffff10b7700 1 mds.0.23 handle_mds_map i am now mds.0.23 2017-08-21 16:13:47.543616 7ffff10b7700 1 mds.0.23 handle_mds_map state change up:reconnect --> up:rejoin 2017-08-21 16:13:47.543623 7ffff10b7700 1 mds.0.23 rejoin_start 2017-08-21 16:13:47.543638 7ffff10b7700 1 mds.0.23 rejoin_joint_start 2017-08-21 16:13:47.543666 7ffff10b7700 1 mds.0.23 rejoin_done 2017-08-21 16:13:48.544768 7ffff10b7700 1 mds.0.23 handle_mds_map i am now mds.0.23 2017-08-21 16:13:48.544771 7ffff10b7700 1 mds.0.23 handle_mds_map state change up:rejoin --> up:active 2017-08-21 16:13:48.544779 7ffff10b7700 1 mds.0.23 recovery_done -- successful recovery! 2017-08-21 16:13:48.544924 7ffff10b7700 1 mds.0.23 active_start 2017-08-21 16:13:48.544954 7ffff10b7700 1 mds.0.23 cluster recovered.
