Nagios Upgrade Process with PCS cluster Dated 7th May 2022 - Tetra Support Staff - Biswajit Banerjee

Video summary: [SPARSE TRANSCRIPT - long screen-share session with minimal narration] "Spectra nagios upgrade on PCS cluster platform" -- a ~1.5 hour hands-on walkthrough upgrading the Spectranet Nagios monitoring server running on a PCS/DRBD cluster. The recovered narration fragments are consistent with the title: stopping the PCS cluster ("pcs cluster stop"), stopping DRBD replication, reconfiguring the virtual IP, rsyncing roughly 177GB of monitoring data across, then restarting and validating the cluster came back up successfully with the upgrade complete. Ends with a reminder to the team to confirm the next scheduled backup runs. Given how sparse the transcript is, treat this summary as a rough guide rather than a precise record -- the actual command sequence would need to be checked against the recording.
