Subject Re: Cloudbees Operations Center and Client Masters upgrade this weekend.
Date Sun, 05 Apr 2020 16:32:29 GMT
Hi All,

This is now completed.

Overall time spent was around 3 hours on the Operations Center and 5
masters.

When the OC was being upgraded, there was no downtime for the masters.

Each master had downtime of around 20 minutes to 30 minutes, including
multiple restarts
, backups and plugin upgrades.

CouchDB folks - most of your nodes are connected via 'node connects to the
master' meaning that you'll
have to update each slave.jar manually. The preferred method is ssh i/o
non-blocking, all nodes connected
in this fashion all came back on their own without intervention.

Thanks all

Gavin McDonald (ASF Infra)
