I use ceph from this debian repository http://ceph.newdream.net/debian/. So
i use version 0.43. The reason why i decide use pacemaker is delays that
happens periodically(time to time perhaps when client try to connect to
failed mon) if one monitor in cluster will fail (in my case crash). I think
that if monitor in fail case will move to health node i remove this
delayes. But in may case i doesn't have success:-(((( (i try use haproxy,
try to launch one monitor which will migrate to heath node)
