moving shards to new hosts.
YadavRatnesh opened a new issue #2640: Seeing error after moving shards to new hosts.
URL: https://github.com/apache/couchdb/issues/2640
[NOTE]: # ( ^^ Provide a general summary of the issue in the title above. ^^ )
## Description
We wanted to move our 3 node cluster to a 8 node cluster. I followed the steps mentioned in https://docs.couchdb.org/en/2.3.1/cluster/sharding.html#moving-a-shard.
After I removed old nodes from the cluster and database configs, I am seeing following error from all of new nodes,
_**[error] 2020-03-06T08:32:54.902589Z couchdb@NewNode1 emulator -------- Error in process <0.8567.3867> on node 'couchdb@cNewNode1' with exit value:
{{rexi_DOWN,{'couchdb@Old’Node1,noconnect}},[{mem3_rpc,rexi_call,2,[{file,"src/mem3_rpc.erl"},{line,349}]},{mem3_rep,calculate_start_seq,1,[{file,"src/mem3_rep.erl"},{line,349}]},{mem3_rep,repl,1,[{file,"src/mem3_rep.erl"},{line,218}]},{mem3_rep,go,1,[{file,"src/mem3_rep.erl"},{line,83}]},{mem3_sync,'-start_push_replication/1-fun-0-',2,[{file,"src/mem3_sync.erl"},{line,211}]}]}**_
- These error messages are logged in thousands per minute per node
- All the error are coming only for one of old node.
- None of old machines shows up '@localhost:5984/_membership' request.
## Steps to Reproduce
Move the shards to new hosts - https://docs.couchdb.org/en/2.3.1/cluster/sharding.html#cluster-sharding-remove-shard-files
## Expected Behaviour
There should not be any errors
## Your Environment
[TIP]: # ( Include as many relevant details about your environment as possible. )
[TIP]: # ( You can paste the output of curl http://YOUR-COUCHDB:5984/ here. )
* CouchDB version used: 2.3.1

## Additional Context
I am also seeing following warning in the logs
