Re: [Linux-cluster] Basic Active Active File Server



Hi Paul..

I have done a crm_tool leave force on the nodes in an attempt to get
them to join back in, but they simply form a cluster on their own. I
have asked about the igmp and have been told that it is not running on
the network,

Since this is a test system I have built it on ESX, one node in each
of our datacenters, I am now moving both of the nodes to the same ESX
server and will try again.
