We've finally shut down the old Analytics Kafka cluster. We've been trying to do this for 1.5 years!
Kafka has been shut down and removed. role::spare::system is applied and [[ https://gerrit.wikimedia.org/r/c/operations/puppet/+/519034 | related puppet code has been removed ]]. Old graphite based Grafana dashboards have been removed.
I believe the next steps are those starting here https://wikitech.wikimedia.org/wiki/Server_Lifecycle#Steps_for_DC-OPS_(with_network_switch_access).
Thank you!

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)
[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:**
[x] - disable puppet on host
[x] - power down host
[x] - update netbox status to Decommissioning (if decom) or Planned (if spare)
[x] - disable switch port
[x] - switch port assignment noted on this task (for later removal) - asw2-a-eqiad:ge-2/0/17
[] - remove all remaining puppet references (include role::spare)
[] - remove production dns entries
[x] - puppet node clean, puppet node deactivate (handled by wmf-decommission-host)
[x] - 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.**
[] - 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.
