Hi! I'm using ceph (0.80.5) in docker (http://github.com/ulexus/docker-ceph) with host networking.
When I have one osd per host, it works just fine. When I have only one node with several osds on the same host, it works fine too. But when osds are on many nodes and some node has more that one, this go crazy. OSDs create many threads and accept connections from other osds, loading 8 cpu server to 60%. Most of the load is in system (many packets and interrupts), osds only report 150-200% cpu usage in htop. This happens without any load on cluster, with empty osds. This behavior does not depend on amount of mds, I tried with 1 and 3 mds. What could be wrong with my setup? Did I miss something in docs? I asked docker-ceph author and he seems to have the same problems. -- Regards, Ian Babrou http://bobrik.name http://twitter.com/ibobrik skype:i.babrou
