Hello,

The current primary master for m1 (db1063), which is mostly for internal services + etherpad isn't in a great healthy status: it is an old host, which needs to be decommissioned and which is having disks failing pretty much every week (plus disks on predictive failure).

We have decided to fail it over one of the newer hosts, db1135: https://phabricator.wikimedia.org/T231403

We have scheduled this switchover for: Tuesday 10th September at 16:00 UTC

This failover should be rather quick and would only take a few seconds (while we re-load the haproxy) - during those few seconds, the following services will be on read-only:

bacula etherpadlite librenms puppet racktables rt

Communication will happen at #wikimedia-operations If you are around at that time and want to help with the monitoring, please join us!

Thanks
