You seem to be saying that the log messages I see labelled "openais" are not actually from ais, but from some piece of the cman servce (ccsd?). So, where is aisexec logging to? 2. Like I said, I *do* see multicast traffic on the address I configured in openais.conf, and I do see aisexec bound to that IP. I do not see anything attempting to use this hash-derived default address. When you say "a cman cluster will always have ..." do you mean that the cluster will use *both* multicast addresses? In my case, the cluster is failing, which is why I'm looking into what openais is doing, so the fact that I don't see anything using the 239.192 address doesn't mean nothing would be using it if cluster startup were successful. However, there's no actual "cman" entity anymore in CentOS/RHEL 5, and my ccsd is running. -- Cos _______________________________________________ Openais mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/openais
