And also very very old hardware.

Consider upgrading to buster directly and mariadb 10.3.

@Andrew any plans to get buster on Cloud VPS soon?

This task probably needs to be reworded or just merged into T193264: Replace labsdb100[4567] 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.

Sounds good. I was pretty sure that wasn't yet in the works. The version of mariadb on buster might resolve some bugs for us :)

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 :-)

In theory the last parts needed to fix the raid controllers on cloudvirt10{19,20} are on order.
