> Key: COUCHDB-2484
> URL: https://issues.apache.org/jira/browse/COUCHDB-2484
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 1.x.x
> Reporter: Gunther Gruber
>
> We are Using Couchdb Version 1.2.0 with 8.3T of data, biggest Database ist
> 2.1T. At this moment we switch to new hardware with more storage space. We
> copied the files with rsync and started the replication.
> One system is already in sync, the other is doing the replication.
> I appreciate that besides the errors in the log, the first system is now in
> sync.
> The log looks like the following
> Retrying POST request to http://replication:XXXX/database/_revs_diff in 0.5
> seconds due to error req_timedout
> and then
