CloudVPS reboots for security updates
by Arturo Borrero Gonzalez 29 Jul '19

29 Jul '19

Hi there! Unrelated to other operations that were communicated recently (datacenter PDU upgrades, operating system upgrades, etc) we need to reboot all the cloudvirt servers to introduce some security updates for CPU vulnerabilities. Along with the physical hardware reboot we also need to reboot all the virtual machines running in CloudVPS. This operation is a bit disruptive but very quick and should not lead to any unexpected errors (is just a reboot). We already tried the same upgrades in some other servers. We will be doing the reboots during this week (starting 2019-07-29). If you see any problems related to this, please contact us. regards. -- Arturo Borrero Gonzalez SRE / Wikimedia Cloud Services Wikimedia Foundation

PDU upgrades in the eqiad datacenter affects CloudVPS hypervisor
by Arturo Borrero Gonzalez 25 Jul '19

25 Jul '19

Hi there! There is an ongoing maintenance in the eqiad datacenter that involves changing power connectors of the servers. More info in this phabricator task: T226778 [0]. The PDU upgrade could potentially leave our hypervisors without power briefly. For some hypervisors, we plan to take the risks of leaving them running. For some other hypervisors (those running important DBs in the form of virtual machines) we will probably do a controlled shutdown before the operations to ensure no data corruption happen in the databases. The PDU upgrades will happen this very week (see phab task [0]) and it could potentially affect every virtual machine we run in CloudVPS. This includes Toolforge. In the case of power loss, we expect the disruptions to be very briefly and to don't cause extended downtime in any case. Please, let us know any issue you may find related to this operation. regards.

Check my write up of the DNS naming proposal
by Bryan Davis 19 Jul '19

19 Jul '19

I saw Arturo referring to the decisions we made in Dublin about DNS naming in a phab task today. When I went to look at the page on Wikitech I realized that we had not strongly signaled there what the outcome of the discussions were and that there was a bit of ambiguity in the "winning" proposal. I have attempted to write up what I believe we collectively agreed on as <https://wikitech.wikimedia.org/wiki/Wikimedia_Cloud_Services_team/Enhanceme…>. Please review this write up and be ready to quickly thumbs up/thumbs down the write up in the 2019-07-23 WMCS team meeting. Folks on this list who do not attend that meeting but who wish to object to the write up can do so by responding to this thread. +1 votes via email are not necessary.
