Renaming a peers hostname seems to require manually rewriting (automatically generated) configuration files. The "peer probe" command only allows limited renaming during initialization. There should be a new command (or maybe an extended "peer probe") that allows changing the hostname of a peer including all the bricks. (Changes regarding bricks are currently required, but shouldn't be, as described in Bug 765437.)

This comes up frequently on IRC. Could we bump the severity?
+10 vote for a utility to manage the "known peer" connection information. I have added a new storage network to my ovirt/gluster system but I can not remove the "VM data" network from the servers.
