Hi Cephers, What is your "best practice" for starting up OSDs?
I am trying to determine the most robust technique on CentOS 7 where I have too much choice: udev/gpt/uuid or /etc/init.d/ceph or /etc/systemd/system/ceph-osd@X 1. Use udev/gpt/UUID: no OSD sections in /etc/ceph/mycluster.conf or premounts in /etc/fstab. Let udev + ceph-disk-activate do its magic. 2. Use /etc/init.d/ceph start osd or systemctl start ceph-osd@N a. do you change partition UUID so no udev kicks in? b. do you keep [osd.N] sections in /etc/ceph/mycluster.conf c. premount all journals/OSDs in /etc/fstab? The problem with this approach, though very explicit and robust, is that it is is hard to maintain /etc/fstab on the OSD hosts. - Anthony _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
