Rebalance after adding new node failed

Couchbase Server
1

I’m currently in Couchbase 2.1.1. I need to updgrade two of my nodes to 2.2.0 so I added one extra server for temporary swapspace and it happens to be 2.0.1. Once I have added the new server and I clicked rebalance, I got this error:

Rebalance exited with reason {unexpected_exit,
{‘EXIT’,<0.6995.1477>,
{badmatch,
[{‘EXIT’,
{{badmatch,{error,ehostunreach}},
{gen_server,call,
[<16025.11383.0>,had_backfill,30000]}}},
{‘EXIT’,
{shutdown,
{gen_server,call,
[<0.6992.1477>,had_backfill,30000]}}}]}}}

I’m guessing it has something to do with host unreachable which is strange consider I have opened up all the necessary ports and they all can ping each other. and just for the giggle, I turned off all the firewall and I’m still having the same problem.

I was thinking perhaps it’s because the new server I’m trying to add is couchbase 2.0.1. However after I upgraded the 2.0.1 to 2.1.1, I’m still seeing the same problem. Please advise?

Many thanks.

Can you share the ports you have open?

Sure. Here you go straight from the firewall…
