Hello, I have encountered a strange I/O freeze while rebooting one OSD node for maintenance purpose. It was one of the 3 Nodes in the entire cluster. Before this rebooting or shutting down and entire node just slowed down the ceph, but not completely froze it. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
