HostFile backend for Cumin in Cloud VPS land
by Madhumitha Viswanathan 30 Jan '18

30 Jan '18

Hey all, Clush allows for host targeting using a file that has a list of hosts, using the --hostfile option. Thanks to Riccardo's awesome work, we now have this feature available as a Cumin backend in Cloud VPS cumin masters (including labs-puppetmaster). This is something we need when we have to target a list of hosts that are not dynamically queryable, say where puppet runs are failing, or hosts that have NFS enabled. Sometimes these lists are too long and not fun to pass as a comma separated list of hostnames through cumin's Direct backend. Do use with care, and make sure to check that your hostfile is current, and has the right hosts you are looking to target. If in doubt, --dry-run :) Docs on how to use are here - https://wikitech.wikimedia.org/wiki/Cumin#HostFile_backend_(Enabled_only_in… Best, -- Madhumitha Viswanathan Operations Engineer, Cloud Services

on-call notes 2018-01-16 2018-01-23
by Andrew Bogott 22 Jan '18

22 Jan '18

Note that I will be traveling tomorrow and will miss our weekly meeting (unless today's snowstorm continues and my flight is delayed). Note also that Franciso has been quite on top of things in #wikimedia-cloud and I consequently didn't up doing much support there. \o/ 2018-01-16: * Lots of alerts, all of them caused by me rebooting labvirts * A fair but of chatter on #wikimedia-cloud, also a result of the reboots 2018-01-17: * Rush job: Created some Trusty VMs for the Discovery team to run a demo next week: https://phabricator.wikimedia.org/T185131 * Followed up on 'NCCIC Incident number INC000010157486' and created https://phabricator.wikimedia.org/T185383 * More alerts, also self-inflicted due to meltdown reboots 2018-01-18: * Granted a few tools membership requests 2018-01-19: * Cleared out some logfiles on labtestnet2001 in response to an icinga alert about disk space 2018-01-20: * Responded to a bitninja email and they actually responded and whitelisted us! (Or at least said they did) 2018-01-21: * Granted a few more tools membership requests 2018-01-22: * Responded to complaints about ssh access failing. This turned out to be my fault, the result of a bad ldap patch. * Deleted the 'gitblit' project which has been unused for some time * Ops meeting ** Full etherpad at https://office.wikimedia.org/wiki/Operations/Operations_Meeting_Notes/SRE-2… ** Meeting was sparsely-attended and brief ** Received a tip of the hat for finally upgrading everything to puppet 4 ** Keith mentioned the puppet-apply vs. Trusty issue but everyone sounded satisfied with the additional-backport fix ** From etherpad but not discussed: [CLOUD/releng? heads up] Moving some wikis to s5? T184805 Cloud/releng to provide some feedback
