Subject Re: 5 node cluster - Recommended seed configuration.
Date Tue, 09 Aug 2011 05:28:11 GMT
Hi,

Rule of thumb, you should identify two servers in the cluster to be your
seed nodes.
And all the servers should point to these two seeds..

You should bring up the seed nodes first with autobootstrap set to false..
All other nodes should be added to the ring with autobootstrap=true and
pointing to the same seed nodes.
