Description

Steps for service owner:

  • - all system services confirmed offline from production use
  • - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place. (likely done by script)
  • - remove system from all lvs/pybal active configuration
  • - any service group puppet/hiera/dsh config removed
  • - remove site.pp, replace with role(spare::system) recommended to ensure services offline but not 100% required as long as the decom script is IMMEDIATELY run below.
  • - login to cumin host and run the decom cookbook: cookbook sre.hosts.decommission <host fqdn> -t <phab task>. This does: bootloader wipe, host power down, netbox update to decommissioning status, puppet node clean, puppet node deactivate, debmonitor removal, and run homer.
  • - remove all remaining puppet references and all host entries in the puppet repo
  • - reassign task from service owner to DC ops team member depending on site of server.

End service owner steps / Begin DC-Ops team steps:

  • - system disks removed (by onsite)
  • - determine system age, under 5 years are reclaimed to spare, over 5 years are decommissioned.
  • - IF DECOM: system unracked and decommissioned (by onsite), update netbox with result and set state to offline
  • - IF DECOM: mgmt dns entries removed.
  • - IF RECLAIM: set netbox state to 'inventory' and hostname to asset tag

[operations/puppet@production] hieradata: decom ms-be20[16-27] from swift

https://gerrit.wikimedia.org/r/665298

I will be taking ms-be2016, after talking to @fgiunchedi, temporarily (probably just for a week) to test swift media production backups on codfw before ordering new ones at T264672. CC @LSobanski.

I intend to change the role and reimage it (including wiping its disks), and use it to store test backups. I was told they have been fully depooled from swift and firewalled its service.

ms-be2016 seems to be at the moment with healthy disks.

Please do not send it for decom. yet until after the performance test: T267338

Completed auto-reimage of hosts:

['ms-be2016.codfw.wmnet']

and were ALL successful.

I will no longer be using ms-be2016 or any other host. They can be freely decommissioned. Let me know if you need help with any of the tasks involving them.
