Hi. I'm having problems when a one of the nodes changes its hostname (uname -n).
In first place, if the hostname is changed the cib doesn't get updated so the '#uname' attribute is still seen as the old one in all the nodes of the cluster. This is a minor problem, since the cluster keeps working as if the hostname wasn't been changed. The major problem arises when the node with the hostname changed reboots (a heartbeat reload causes the same effect). When this happens, that node can't see the others and no one can see it either. In the logs there are messages like these: Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_slave_all message (84) from i300b: not in our membership Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (86) from i300b: not in our membership Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_replace message (88) from i300b: not in our membership Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (8a) from i300b: not in our membership Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (8b) from i300b: not in our membership Jun 13 16:25:44 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (8c) from i300b: not in our membership Jun 13 16:25:45 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (8f) from i300b: not in our membership Jun 13 16:25:45 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (90) from i300b: not in our membership Jun 13 16:25:46 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (92) from i300b: not in our membership Jun 13 16:25:46 p8100 cib: [19345]: WARN: cib_peer_callback:callbacks.cDiscarding cib_apply_diff message (93) from i300b: not in our membership (i300b is the new hostname) Shouldn't be the uuid used instead the hostname in every places to avoid this kind of problems?
