I'm currently looking at the same scenario of having to restart crashed OSDs. I'm looking towards using runit (http://smarden.org/runit/ & http://smarden.org/runit/useinit.html) to manage the OSD's...I'll probably modify my init script to send me a trap or email when it's restarted though. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
