decommission wdqs1015.eqiad.wmnet
Closed, ResolvedPublicRequest

Description

The server has failed and is currently out of warranty. The failure is documented in T427852.

Replacement servers have already been received and are awaiting deployment. Required Puppet updates are being tracked under T423314

This task will track the decommission-hardware of server wdqs1015.eqiad.wmnet.

With the launch of updates to the decom cookbook, the majority of these steps can be handled by the service owners directly. The DC Ops team only gets involved once the system has been fully removed from service and powered down by the decommission cookbook.

wdqs1015

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
  • - 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 no owner and ensure the site project (ops-sitename depending on site of server) is assigned.

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.

Decom cookbook ran; the part that requires the host to be online failed since the host is down, which was expected.
