863275 - decommission old puppet servers

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: Puppet, task)

Description

[Amy Rich [:arr] [:arich]]

The following host needs to move off of kvm in scl3:

scl3-production-puppet.srv.releng.scl3.mozilla.com

Likely the better route is to convert the machines in scl3 that use it over to using puppetagain.  This includes:

* The few remaining bld-centos5 vmware vms (which are slated to be decommissioned)
* dev-stage01.srv.releng.scl3.mozilla.com (which is slated for replacement)
* preproduction-stage.srv.releng.scl3.mozilla.com (which should also be slated for replacement as well as dev-stage01 since we're re-architecting the product delivery chain).
* bld-lion-r5-* which we've been discussing dissecting and redoing the image of since we have no way to modify the image as things stand now

Puppet on scl3-production-puppet is now disabled, so likely we can consider this done.  The host is still running in case we need it.

Comment 2

[Amy Rich [:arr] [:arich]]

bld-lion-r5-* is now using the puppet 3.x servers.
bld-centos5 vmware vms are unmanaged
dev-stage01.srv.releng.scl3.mozilla.com is unmanaged
preproduction-stage.srv.releng.scl3.mozilla.com is unmanaged

We should set a date to delete this server.  Does it have any needed information on it that's not already in hg?

[Chris Cooper [:coop] (he/him)]

Answered in email: Dustin backed up the rpms, so we're good to go here.

Comment 4

[Amy Rich [:arr] [:arich]]

Morphing this bug to be a decommissioning bug for all old puppet servers.  The following machines are now shut down and awaiting deletion.  If no problems arise, they will be deleted on 2013-07-15:

scl3-production-puppet.srv.releng.scl3.mozilla.com
staging-puppet.srv.releng.scl3.mozilla.com

scl-production-puppet.build.scl1.mozilla.com
master-puppet1.build.scl1.mozilla.com

releng-puppet1.build.mtv1.mozilla.com
mv-production-puppet

[Dustin J. Mitchell [:dustin] (he/him)]

For the record: I backed up /N and /etc/puppet on all of the old production masters.  There's nothing to back up on releng-puppet1.build.mtv1 (I was just lazy and didn't delete it).

And I'd like to leave scl-production-puppet turned off but not deleted until KVM dies, in case it can be useful in restoring an r3 refimage.
