Issue/Introduction

rsync process is not running on vertica. This process is not running on all cluster servers.

[ ~]$ ps -ef | grep rsync

user   385807 385733  0 05:20 pts/0    00:00:00 grep rsync

[ ~]$ lsof -i :50000 -S

[ ~]$

 

 

 

Environment

Release : 3.x

 

Cause

rsync is used by Vertica for things like copy cluster and backups.
it is not a persistent daemon

Resolution

There is no need for rsync to be always running for the proper operation of your Vertica data base.

As long as it starts when needed, there is no problem with the rsync process stopping when not needed.

NOTE: the script that calls rsync (vbr.py) does not stop the process, so once invoked, it may remain running until next reboot.
