Hi, thanks for bug report. This is problem in corosync parser, which removes trailing ::, so address will end up being fc00 (what is invalid IPv6 address and is handles as dns name). Problem is now fixed in upstream as c04af91ada3c4ca29643cad599ed5605f6bb10bd. There is also another problem in parsing with extra close brace. This is fixed by 60a9f809c17d6cfe73c34263233dbf8e4677d6b5. Thanks again for BZ, closing as upstream. |
Created attachment 682396 [details] Working IPv6 UDPU corosync.conf Description of problem: Corosync 1.4.1 does not support IPv6 double colon notation in /etc/corosync/corosync.conf totem section, starts successfully according to logs but fails to start the actual service. Version-Release number of selected component (if applicable): [root@ns4 corosync]# corosync -v Corosync Cluster Engine, version '1.4.1' Copyright (c) 2006-2009 Red Hat, Inc. How reproducible: Always. Steps to Reproduce: 1. Use an IPv6 memberaddr and bindaddr, with double colon notation to shorten the address, in /etc/corosync/corosync.conf's totem section. 2. service corosync start 3. Watch the service fail to come up, check logs to see incomplete startup sequence. Actual results (with double colon notation): ================================================================== [root@ns4 corosync]# service corosync start Starting Corosync Cluster Engine (corosync): [FAILED] Meanwhile, in /var/log/cluster/corosync.log: Jan 18 11:39:42 corosync [MAIN ] Corosync Cluster Engine ('1.4.1'): started and ready to provide service.

Using V1 and V2 of the synchronization engine. ================================================================== Additional info: Attached is the corosync.conf that works. To make it fail, replace fc00:1c7:da7a:3:0:0:0:0 with fc00:1c7:da7a:3:: and repeat this for every other IPv6 address in the config. I've also tried running this with debug: on, but no extra log messages were dumped.
