What impact does rebooting nodes in a ceph cluster have on the health of the ceph cluster? Can it trigger rebalancing activities that then have to be undone once the node comes back up? I have a 4 node ceph cluster each node has 11 osds. There is a single pool with redundant storage. If it takes 15 minutes for one of my servers to reboot is there a risk that some sort of needless automatic processing will begin? I'm assuming that the ceph cluster can go into a "not ok" state but that in this particular configuration all the data is protected against the single node failure and there is no place for the data to migrate too so nothing "bad" will happen. Thanks for any feedback. ~jpr _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
