Vertica DB Process Start and Stop

[GauravK]

​I am trying to test on how to gracefully stop and start again Vertica process in one of the DB node.
I stopped DB using Admin Tools but still vertica process was running in Linux as mentioned below:

efadmin    2096      1  0 Jan31 ?        00:00:00 /bin/bash /opt/vertica/agent/agent.sh /opt/vertica/config/users/efadmin/agent.conf

efadmin    2104   2096  0 Jan31 ?        00:42:02 /opt/vertica/oss/python/bin/python ./simply_fast.py

efadmin  160917      1  0 Feb01 ?        00:00:00 /opt/vertica/bin/rsync --daemon --config=/tmp/vbr_rsyncd/vbr_rsyncd.conf --port=50000

Please suggest how to stop these process and start it again. what is pre-requisite to be followed?
Do I need to stop the DB first before stopping vertica process.

Hi GuaravK,

What exactly is being tested? What is the goal of the testing?

When stopping the DB via adminTools->Stop Database it only stops the running DB service. That would leave the Vertica software itself that manages the DB, the same services you've listed in your post.

To stop those services on the node being tested on, in adminTools select option 7 for Advanced Menu. Then select option 2 for Stop Vertica on Host.

To restart those services, use adminTools option 5 from the Main Menu for Restart Vertica on Host.

Thanks,
Mike

HI Mike,

Thanks for your response. I tried the option within advanced menu but still on of the vertica process running as below.

 /bin/bash /opt/vertica/agent/agent.sh /opt/vertica/config/users/efadmin/agent.conf​

Do I need to kill vertica process using AdminTool or via Linux kill -9 command.

Basically my end goal is to stop/kill all vertica process running on host as I am monitoring   vertica process thorough NAGIOS and need to test vertica process down.
Restart these process again.
