Issue/Introduction

Copy cluster is failing with following error:

Mon Oct 24 02:00:10 EDT 2022: Starting copy cluster script
Configured backup directories in Mapping are ignored for copy cluster.
Error: Timed out connecting to rsync daemon on host camwpmrep02c port 50000: [Errno 111] Connection refused.
Copycluster FAILED.
Mon Oct 24 02:01:21 EDT 2022: copy cluster finished

Environment

Release : any release

Cause

Check outputs of the following commands:

ps -ef | grep rsync 
lsof -i :50000 -S 

If rsync processes stay running when copy cluster is not ongoing possibly it is stuck.
Same time you may notice that not all nodes are listening on port 50000 IPv4/IPv6

Resolution

1. Double check if port 50000 is not blocked

2. Kill rsync on all nodes

3. Try again:

[[email protected] ~]$ /opt/vertica/bin/vbr.py --debug 3 --task copycluster --config-file /home/dradmin/CopyClusterConfigurationFile.ini

Additional Information

rsync is started by vbr when needed.
If not running at the time of copy cluster not ongoing it is OK.
