You'll need to change the config on each node and then restart it so that the OSDs will bind to the new location. The OSDs will let you do this on a rolling basis, but the networks will need to be routable to each other. Note that changing the addresses on the monitors (I can't tell if you want to do that) is much more difficult; it's probably easiest to remove one at a time from the cluster and then recreate it with its new IP. (There are docs on how to do this.) -Greg > > > > Thanks > > Pankaj > > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
