Re: Can not establish new cluster 5.3 with luci - quorum error

[Alan A <alan.zg@xxxxxxxxx>]

Host file looks OK, pardon my post for my partial hostname editing didn't quite work as expected since my mouse played a game on me. 
We do run Cisco equipment - any pointers on what exactly should I check. I am planning on opening ticket with RH as well.

Xavier - thanks for your suggestion too - will try it.

Looks like network issue to me.

Are you sure your network is operational in a sense of a multicast /
igmp? Try forcing igmp v1 in sysctl.conf - and if you have Cisco
equipment take a look at openais FAQ (mode sparse-dense).
