[Linux-cluster] Cluster RHEL under ESX

[Tiago Cruz]

Hello Guys,

I have a problem in my environment using RHEL 5.2 machines under a
VMware ESX 3.5 - using fence_vmware_ng from Honza.

The cluster works as well, the fence works very good too, but, some
times we lost the quorum:

Mar 19 16:35:21 csd-poa-cla-02 clurgmgrd[2837]: <emerg> #1: Quorum Dissolved
Mar 19 16:35:21 csd-poa-cla-02 openais[2669]: [CLM  ] got nodejoin message 10.11.3.50
Mar 19 16:35:21 csd-poa-cla-02 ccsd[2630]: Cluster is not quorate.  Refusing connection

And we need to reboot all machines to back work.

We try to isolate the multicast communication on another interface
(eth1) connected on another virtual switch, using a dedicated VLAN, but
the problem still happening sometimes, random...

Can you suggest some tip for me?

Thanks!
