Hi,<br>
<br>
Depending on the openais version (please mention it) this behavior
could happen, I've seen it as well, on openais-0.8.0. What I've done to
fix it was to restart the openais process via /etc/init.d/openais
restart. And then it worked, however, this was one of the reasons I
updated the packages to the latest versions of corosync, pacemaker,
etc. The tricky part was doing the migration procedure for upgrading
production servers without service downtime, but that's another story.<br>
<br>
Regards,<br>

hi everybody<br>
I use command service openais stop first to stop openais service and
then use rm -rf /var/lib/heartbear/crm/*? clear all information. then
change multicast address and then use service openais start in another
cluster.<br>
the problem is sometimes it works well I can use crm_mon command. and
sometimes it doesn't work. I use service openais status to check. It
shows Running. but I can not use crm_mon to connect to cluster. <br>
I found the reason may be directory?/var/lib/heartbear/crm/ is empty.
why??if I reboot ,it works again.WHY</div>
<div class="plainMail"> </div>
<div class="plainMail">Now when the is directory is not empty
it sometimes also does not work.<br>
when I use<strong> crm_mon</strong> it shows</div>
