...

sudo systemctl restart ophad omkd opeventsd opchartsd​

Scenario 4 : Clearing datastorage of the nats streams (Main Primary)

1. All vms: (Main Pri, Sec Pri, Pollers, Mirrors)

   Code Block
   sudo systemctl stop ophad

2. Main Primary: Delete all streams 

   Code Block
   nats stream delete --user omkadmin --password op42opha42

   If jq is installed on Main Primary, this below snippet can be used to automate deletion of all nats streams:

   for stream_name in $(nats stream list --user omkadmin --password op42opha42 --json | jq -r '.[]');        do nats stream rm --force --user omkadmin --password op42opha42 "$stream_name"; done

   Verify to check if all streams have been deleted

   Code Block
   nats stream info --user omkadmin --password op42opha42 nats: error: could not pick a Stream to operate on: no Streams are defined

3. Stop the nats-server on Main Primary, Sec Primary and the Arbiter Poller

   Code Block
   sudo systemctl stop nats-server

4. Delete the storage directory

   Code Block
   root@opha-dev7:/home/shankarn# cd /opt/nats/storage/ root@opha-dev7:/opt/nats/storage# ls -lrt total 4 drwx------ 4 root root 4096 Nov 26 11:51 jetstream root@opha-dev7:/opt/nats/storage# rm -rf jetstream/

5. Start the nats-server on Main Primary, Sec Primary and the Arbiter Poller
