In order to continue with T239791: DB: perform rolling restart of mariadb daemons to pick up CA changes we'd need to restart MySQL on m2 host (db1132).
As we have to restart MySQL, we will also upgrade it to the newer version.
These are the used databases m2 currently store:
debmonitor otrs recommendationapi reviewdb (gerrit)
The restart should only take a few seconds, but during that time, those databases won't be available for writes. Reads should remain not affected as the proxy will failover to the standby.
The last restarts we have done have taken between 30 and 60 seconds to be completed, so we expect something similar with this host.
Research can you let us know when can we schedule this restart and if you need to do something from your side?
@Krenair could you help us notifying on the OTRS side once we've picked a date/time?
I plan to email also wikitech-l
