Closed, ResolvedPublic
Actions

Description

meitnerium.wikimedia.org has been replaced by archiva1001.wikimedia.org, so all its resources can be reclaimed and the vm finally deleted.

As far as I know the steps to take to clean up a VM are:

Please do not take any action for the moment since the Analytics team would like to wait a couple of days before irrevocably deleting meitnerium.

note that the docs say "A Phabricator ticket for the decommission of the system should be placed in the hardware-requests project and the appropriate datacenter-specific ops-* project."

I forgot for a moment this is a virtual machine. You can probably ignore that. Sorry.

The steps listed in the description look correct and sufficient to me. There is one thing to add and it would be the removal from DebMonitor per https://wikitech.wikimedia.org/wiki/Server_Lifecycle
