Not exactly, this is "individually" which is not correct. ;) You should indeed "apt-get upgrade" on each node 1,..., 7 but after you should follow this order: 1. restart the monitor daemons on each node 2. then, restart the osd daemons on each node 3. then, restart the mds daemons on each node 4. then, restart the radosgw daemon on each node Regards. -- François Lafont _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
