Can I join a 3rd node to a windows 2012 cluster if the first 2 are using a shared drive?
Posted on 2014-12-09
I am in a situation where we started DR as an after thought. We built our 2 node Windows 2012 cluster, then installed SQL 2012 with alwaysOn and that is working great. However now the company wants to build a data center on the other coast. We have all the network magic in place, I can copy files from node1 (lives in CA) to node 3 (lives in PA), I can connect from SSMS to the instance on node1 all that good stuff. However I am wondering if I can just join node 3 to the existing windows fail over cluster. We don't have shared disk between node1 and node3 and the original windows cluster was built using shared disk between node1 and 2. I was thinking aobut just trying it, but this is a production server, and I don't want to take any unnecessary risks if I can help it.
So....Has anybody out there been in this situation? Any advice?
