Two single node used for swap rebalance
10.6.2.44
10.6.2.45
- Do several rebalance in and out nodes in swap rebalance. There was one time I see popup message saying that cluster ran out of space in one node.
- Check that node and saw data path point to default path (/opt/couchbase/var/lib/couchbase/data)
- The next time I ran rebalance, I setup custom path to node before add them to cluster. Node did not save custom path but showing default path
- Only way to save custom path before add node to cluster was reboot couchbase server. Then I could save custom path on that node
