Hi all, We have a small ceph cluster running version 0.80.1 with cephfs on five nodes. Last week some osd's were full and shut itself down. To help de osd's start again I added some extra osd's and moved some placement group directories on the full osd's (which has a copy on another osd) to another place on the node (as mentioned in http://ceph.com/docs/master/rados/troubleshooting/troubleshooting-osd/) After clearing some space on the full osd's I started them again. After a lot of deep scrubbing and two pg inconsistencies which needed to be repaired everything looked fine except the mds which still is in the replay state and it stays that way. The log below says that mds need osdmap epoch 1833 and have 1832. 2014-08-18 12:29:22.268248 7fa786182700 1 mds.-1.0 handle_mds_map standby 2014-08-18 12:29:22.273995 7fa786182700 1 mds.0.25 handle_mds_map i am now mds.0.25 2014-08-18 12:29:22.273998 7fa786182700 1 mds.0.25 handle_mds_map state change up:standby --> up:replay 2014-08-18 12:29:22.274000 7fa786182700 1 mds.0.25 replay_start 2014-08-18 12:29:22.274014 7fa786182700 1 mds.0.25 recovery set is 2014-08-18 12:29:22.274016 7fa786182700 1 mds.0.25 need osdmap epoch 1833, have 1832 2014-08-18 12:29:22.274017 7fa786182700 1 mds.0.25 waiting for osdmap 1833 (which blacklists prior instance) # ceph status cluster c78209f5-55ea-4c70-8968-2231d2b05560 health HEALTH_WARN mds cluster is degraded monmap e3: 3 mons at {th1-mon001=10.1.2.21:6789/0,th1-mon002=10.1.2.22:6789/0,th1-mon003=10.1.2.23:6789/0}, election epoch 362, quorum 0,1,2 th1-mon001,th1-mon002,th1-mon003 mdsmap e154: 1/1/1 up {0=th1-mon001=up:replay}, 1 up:standby osdmap e1951: 12 osds: 12 up, 12 in pgmap v193685: 492 pgs, 4 pools, 60297 MB data, 470 kobjects 124 GB used, 175 GB / 299 GB avail 492 active+clean # ceph osd tree # id weight type name up/down reweight -1 0.2399 root default -2 0.05997 host th1-osd001 0 0.01999 osd.0 up 1 1 0.01999 osd.1 up 1 2 0.01999 osd.2 up 1 -3 0.05997 host th1-osd002 3 0.01999 osd.3 up 1 4 0.01999 osd.4 up 1 5 0.01999 osd.5 up 1 -4 0.05997 host th1-mon003 6 0.01999 osd.6 up 1 7 0.01999 osd.7 up 1 8 0.01999 osd.8 up 1 -5 0.05997 host th1-mon002 9 0.01999 osd.9 up 1 10 0.01999 osd.10 up 1 11 0.01999 osd.11 up 1 What is the way to get the mds up and running again? I still have all the placement group directories which I moved from the full osds which where down to create disk space.
