by Madhumitha Viswanathan 02 Jan '18

02 Jan '18

Hi all, There was no ops meeting this week, here are the things I looked at during clinic duty last week: * Debugging and fixing PAWS ** https://phabricator.wikimedia.org/T183142#3862801 ** Pending: Removing the blacklist for overlayfs for paws cluster. * Wiki-replica analytics high replag reports on mailing list ** Created https://phabricator.wikimedia.org/T183983 following the discussion in today's meeting. ** Need to follow up with DBAs * Followed up on tools and misc high NFS storage utilization ( https://phabricator.wikimedia.org/T183920) and made subtasks for the relevant project admins. * There were couple reports of the bastion being slow, but both times got resolved by folks other than me before I even got to look at the pings * Resolved a bunch of toolforge membership requests * Extended icinga downtime for labtestcontrol2003 * Found puppet staleness in labstore1004 & 5 - Chase has already looked at this and resolved. * I responded to production pages for pdfrender late night on Christmas Eve and restarted services on scb1001-4 to resolve since I was the only one around. * The cloud list was active this week! ** People helping yay! *** https://lists.wikimedia.org/pipermail/cloud/2017-December/000137.html *** https://lists.wikimedia.org/pipermail/cloud/2017-December/000149.html ** Bryan is awesome at responding to user questions - https://lists.wikimedia.org/pipermail/cloud/2017-December/000136.html ** Concerning long thread on user tables https://lists.wikimedia.org/pipermail/cloud/2017-December/000112.html That's all I think! Best, -- Madhumitha Viswanathan Operations Engineer, Cloud Services

Setup gcal to show your local working hours
by Bryan Davis 02 Jan '18

02 Jan '18

I was shuffling a meeting for next week around today and noticed that only Arturo and I have working hours set in our Google Calendar profiles. I think it would be useful for everyone to configure their calendar to show their comfortable working hours to make it easier for me and others to set meetings without doing a lot of mental math about if it is too early or too late for someone to join. You do this by clicking the "cog" icon in the gcal UI, selecting 'Settings' and then 'General > Scheduling' in the left hand navigation menu.

Kubecon 2017 Offsite Outcomes and archiving
by Chase Pettet 14 Dec '17

14 Dec '17

*Original:* https://etherpad.wikimedia.org/p/kubecon-2017-offsite-agenda *Archived on office wiki:* https://office.wikimedia.org/wiki/Wikimedia_Cloud_Services/Offsite_Notes/ku… *Decided:* - Stick with Trusty through Neutron migration (for now as we think we are making enough progress on this to ensure Trusty sunset by April 2019. Xenial seems to have Mitaka so if we have to potentially we can match mitaka there with Trusty for a migration of OpenStack releases across releases but that's work we don't want to do and we need to settle on a distro (see: figure out deployment methodology)) - https://phabricator.wikimedia.org/T166845 to be done via cumin for now (long term prometheus?) - draw.io is a canonical tool - Dumps work is a carry over goal - Neutron will be a carry over goal but hopefully not a literal one *Open Near Term:* - Neutron Plan: talk about the naming of deployents - Need to do hard capacity thinking on storage scaling and budgeting - icon templates for draw.io *Open Long(er) Term:* - Need to figure out openstack components deploy methodology (containers, source, distro packaging...) - Is SLURM viable? - kubeadm for Kubernetes deploy? - Tools Bastion and resource issues - Is there an upstream alternative that is viable for Quarry? - How much do we fold into cloud-init? - Do we use puppet standalone and virtualize the main cloud masters? - Hiera for instances is a mess and needs to be rethought. - Trial of paging duty cycles (while still taking advantage of our time spread) - How much of labtest is ready for parity testing? - Document undoing standalone puppetmaster setup *Missed because of time:* - - - puppet horizon interface future ( https://phabricator.wikimedia.org/T181551 and co) - - FUTURE IDEAS: NOT EXISTING - - new TLDs for public and internal addresses: when and how to deploy - - new ingress for HTTPS in VPS and Toolforge? - - monitoring sanely - - thinking about ceph - - metrics for end-users - who uses my tools and how? ( https://phabricator.wikimedia.org/T178834 and co) I would like to talk about the missed items if we can find a few minutes at all hands (over dinner?) -- Chase Pettet chasemp on phabricator <https://phabricator.wikimedia.org/p/chasemp/> and IRC
