Different OS updates:
recommended procedure (also it works without stopping the services, but is recommended to stop them first).
-
Stop services with ver_stop command on the server (bash /etc/veridiumid/scripts/veridium_services.sh stop)
-
Do os update or other operation
-
Reboot servers – the services will start automatically
-
Run check_services to see that all services are up and running (green), before going to next server.
-
Normally the services will go up in 3,4 minutes after a reboot.
-
You need to look specifically for elasticsearch – cluster in status green, cassandra – all nodes are in UN status, zookeeper – all nodes are up in the cluster – one leader and 2 followers.
Java update:
