Both servers are running Windows 2012 R2.
At the start both node-01 and node-02 are running 4.6.4-4590 in a single cluster.
I did the following.
- Click fail over on node 2 so that at the end I have a single cluster running on node 1
- On Node 2 - uninstall CB 4.6.4 and install CB 5.0.1
- Join the cluster on node 1 (still running 4.6.4)
- Click the rebalance button and it eventually fails - sometimes it makes it further into the process but it never seems to complete
To get back to a stable cluster I did the same process on node 2 but with the 4.6.4 install and it worked fine. Note that I was originally running version 4.5.0-2601 when I started. When I started having issues I upgraded both nodes to 4.6.4 (using this process) to see if that would help with the upgrade to 5.0.1. The upgrade to 4.6.4 went fine - but did not help with the issue upgrading to 5.0.1. I did do this process in a test environment and it worked fine going to 5.0.1 - but the test environment has less data.
This environment has 2 buckets - one bucket has 126K documents and the other has 2.9 Million documents.
