Posted: Wed Jan 10, 2024 12:52 am
Hi all,
Our patching team is planning to implement RHEL8.6 update to our 4 instances Nagios Log server. This has never been done. In fact this is my first time involve in OS update for NLS. My basic understanding on the steps would be as below (if to update server one-by-one) :
1. Precheck of the servers
2. Backup and snapshot of the server and NLS
3. Stop elasticsearch and logstash
4. Patching team proceed with the update and reboot the server
5. Check for the server and also elasticsearch and logstash
6. Repeat step 3 to 5 for the remaining servers
Do let me know if I miss out on anything above or if there's additional steps needed to be taken.
Apart from that, is it possible to run the OS update concurrently on all 4 servers? or is that not recommended.
Your guidance and suggestion is very much appreciated.
Thank you.
