The pool counters in codfw are now provided by two Ganeti VMs (poolcounter200[12]), subra and suhail can be decomissioned or reclaimed to spares (they're OOW for nearly two years now).
subra:
[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 if system isn't shut down immediately during this process.)
START NON-INTERRUPPTABLE STEPS
[x] - disable puppet on host
[] - remove all remaining puppet references (include role::spare)
[x] - power down host
[x] - disable switch port
[x] - switch port assignment noted on this task (for later removal) asw-a-codfw:ge-5/0/19
[] - remove production dns entries
[] - puppet node clean, puppet node deactivate, salt key removed
END NON-INTERRUPPTABLE STEPS
[] - system disks wiped (by onsite)
[] - system unracked and decommissioned (by onsite), update racktables with result
[] - switch port configration removed from switch once system is unracked.
[] - mgmt dns entries removed.
