We could let ctdb handle client eviction, but this would allow admin keys on the node I guess, something I would not feel comfortable with. The "ceph rados helper", a module you have to compile yourself as it's not shipped by default on CentOS / Ubuntu, works great. Together with the "--exclusive" lock option for "rbd-nbd" this allows for a HA iSCSI (LIO) setup.
