This task will track the #decommission of server db2044.codfw.wmnet
The first 5 steps should be completed by the service owner that is returning the server to DC-ops (for reclaim to spare or decommissioning, dependent on server configuration and age.)
db2044
Steps for service owner:
[x] - all system services confirmed offline from production use
[x] - set all icinga checks to maint mode/disabled while reclaim/decommmission takes place.
[x] - remove system from all lvs/pybal active configuration
[x] - any service group puppet/hiera/dsh config removed
[x] - remove site.pp, replace with role(spare::system) https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/531029/
[x] - unassign service owner from this task, check off completed steps, and assign to @robh for followup on below steps.
Steps for DC-Ops:
The following steps cannot be interrupted, as it will leave the system in an unfinished state.
**Start non-interrupt steps:**
[] - disable puppet on host
[] - power down host
[] - update netbox status to Inventory (if decom) or Planned (if spare)
[] - disable switch port
[] - switch port assignment noted on this task (for later removal)
[] - remove all remaining puppet references (include role::spare)
[] - remove production dns entries
[] - puppet node clean, puppet node deactivate (handled by wmf-decommission-host)
[] - remove dbmonitor entries on neodymium/sarin: sudo curl -X DELETE https://debmonitor.discovery.wmnet/hosts/${HOST_FQDN} --cert /etc/debmonitor/ssl/cert.pem --key /etc/debmonitor/ssl/server.key (handled by wmf-decommission-host)
**End non-interrupt steps.**
[] - Label disk #1 and #2 as failed, so they do not get re-used again
[] - system disks wiped (by onsite)
[] - IF DECOM: system unracked and decommissioned (by onsite), update racktables with result
[] - IF DECOM: switch port configration removed from switch once system is unracked.
[] - IF DECOM: add system to decommission tracking google sheet
[] - IF DECOM: mgmt dns entries removed.
[] - IF RECLAIM: system added back to spares tracking (by onsite)
