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

   * CouchDB version used: 2.3.1
   * Browser name and version:
   * Operating system and version: Docker container 
   
   ## Additional Context
   I am also seeing following warning in the logs
   [warning] $DATE couchdb@core-*****- <0.323.0> -------- mem3_sync
