Description
Build : 5.5.0-2381
Observed rebalance failure with the following error when running system test for multinode failure
Rebalance exited with reason {config_sync_failed, {error, {get_compressed_failed, [{'ns_1@172.23.105.60', {exit, {{nodedown,'ns_1@172.23.105.60'}, {gen_server,call, [{ns_config_remote,'ns_1@172.23.105.60'}, get_compressed,infinity]}}}}]}}} |
Steps:
- create 7 node cluster with KV only
- starting pumping in data with constant ops
- change bucket replica to 2 and rebalance
- set max-autofailover to 2
- now stop couchbase on 2 nodes
- rebalance will remove there 2 nodes
- add back these nodes again
- change bucket replica to 3 and rebalance
- set max-autofailover to 3
- now stop couchbase on 3 nodes and start after 30 sec
- add then as delta recovery
- rebalance node
Last rebalance fails
