I've updated this to include thoughts on how to upgrade postgres to 9.1. I'd like to do this soon (my next Monday, they're usually quiet? There will be a few minutes of total LAVA downtime).
that's cool and including the script is really great.
OK. I'll send an announcement about the downtime today.
Setting up streaming replication to enable us to cut over to the failover system is starting to seem like too much work for this. We could just rsync the postgres data across after shutting down LAVA on control and rsync it back again just before restart it after the upgrade.
The other option is to just take the downtime while the upgrade happens. It really shouldn't that long, but I can't really think of a way to gauge the potential cost ahead of time.
From what I read the downtime would probably be less than 3 minutes. I hate to waist developer *days* to save 3 minutes of uptime.
OK. I'd still like to have a system ready to go as a standby in case the upgrade implodes so that we can continue to accept jobs at least.
Team members, feel free to edit as appropriate. Anyone else with thoughts can add comments.
Still true!
