Hello,
We are going to switchover m5 (wikitech) primary database master on *Tuesday 3rd September at 13:00 UTC *https://phabricator.wikimedia.org/T229657 This switchover will also affect some Cloud services that will be handled on a different announcement.
The current master (db1073) is an old and out of warranty hosts with several disks on predictive failure, it needs to be decommissioned. We will be failing over db1073 to db1133, a newer and more powerful host.
We expect this to take around 15 minutes (or just a few seconds if everything goes fine). *Impact: * *- Writes will be blocked during the switchover* *- Reads will remain unaffected.*
Communication will happen on #wikimedia-operations IRC channel.
Thanks Manuel.
