I've moved a whole set of OSD's from one server to another after a filure.
All other OSD's have come up no problems and Ceph is busy rebalancing itself
after the change, but one of my OSD's is being difficult. Below is the output
from the log file when I use 'service ceph restart osd.35' to try and bring it
online.
I can see any usefull errors here to start chasing down, can you?
