These servers are running Jessie which is too old and is not currently supported by our Puppet automation.
This task probably needs to be reworded or just merged into T193264: Replace labsdb100 with instances on cloudvirt1019 and cloudvirt1020 as a dup. This hardware is waiting to be thrown out and that is blocked by getting cloudvirt1019 and cloudvirt1020 working properly.
I don't think we want to jump into running dbs on buster until after the core DBA team has moved some things to that distro and worked out the kinks. We probably should open a separate ticket about getting Buster base images into Cloud VPS soon though with the existing work by the SRE team to bring up some Buster nodes.

Too late :-) Obviously I am supposing that at the pace we are going, buster may be 6months-1 year into release when the hw is ready :-)
