lov10,lov11,lov12,lov13 provisioned

[Predrag Punosevac]

Dear Autonians,

Four new CPU nodes we received in late September are finally provisioned.
Each one is 88 cores and 768 GB of RAM. I am adding scratch directories
right now but the nodes are should be usable. Let me know if notice
anything strange. The provisioning process is semi-automatic. For the most
part, I just run Ansible playbooks and intervene only to fix corner cases.
Hopefully,  one of these days I will fix my Ansible JSON files so that no
human intervention is needed.

Auton cluster is now in pretty decent shape and well organized in five
server racks. Two of those are not filled to full capacity and I can
provision new CPU or GPU nodes on short notice (in one day under no Covid
restriction).

I will try to fix LOW1 but only after I do a bit of work on file servers. I
have over 600 TB of HDDs laying around and it will take me a while to
populate all available driver bays and replace old HDDs.

Cheers,
Predrag
