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.

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.
Kind regards,
Jasper Siero
