Hi, I've a question on cluster-network documented here: http://ceph.com/docs/master/rados/configuration/network-config-ref/ In the docs we learn for the cluster network directive: The IP address and netmask of the cluster (back-side) network (e.g., 10.20.30.41/24). Set in [global]. You may specify comma-delimited subnets. Two Questions on that: 1) shouldn't that be a NETWORK instead of a single IP? Like 10.20.30.0/24? 2) If I define this in the global section also with the public network directive AFTER having all my productive OSD's up and running, will something very bad happen when I restart OSD by OSD? I don't have to change my network configuration, as I've already defined public and cluster-ips, I just wasn't aware that this configuration existed. I'm running 4 OSD's on this host, and I'm kind of confused by the port numbers it picked (and why there are so many of them): netstat -planet | egrep -E ':68.*LISTEN.*ceph-osd' | awk '{ print $4}' 0.0.0.0:6821 0.0.0.0:6822 0.0.0.0:6823 10.1.91.11:6800 10.1.91.11:6801 10.1.91.11:6802 10.1.91.11:6803 10.1.91.11:6804 10.1.91.11:6805 0.0.0.0:6812 0.0.0.0:6815 0.0.0.0:6818 Wolfgang -- DI (FH) Wolfgang Hennerbichler Software Development Unit Advanced Computing Technologies RISC Software GmbH A company of the Johannes Kepler University Linz IT-Center Softwarepark 35 4232 Hagenberg Austria Phone: +43 7236 3343 245 Fax: +43 7236 3343 250 wolfgang.hennerbichler@xxxxxxxxxxxxxxxx http://www.risc-software.at _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
