lov[7-9] scratch space to be expanded

[Predrag Punosevac]

The scratch space is now added to lov[7-9]. These three machines are
updated to 8.3 including /opt/minconda3 to python 3.8.5

On a related note, I did a quick update (including conda) and inspection of
the CPU computing nodes still running Springdale 7.9 (RHEL 7.9). lov[1-6],
Ari, Foxconn, Athena (9 in total excluding defunct low1). All of those
machines have adequate scratch spaces (mostly 2 TB with additional RAID 10
TB storage available on a few of them). Non the less scratch appears to be
nearly full which limits usability. I would hate to wield my root access to
get things under control. Please be mindful of your fellow Lab scientists.

In case you wonder EOL for Springdale 7.9 is 2024 but it would be good to
upgrade at least newer machines to branch 8.xxx for a number of reasons.
That would have to wait until I have unrestricted access to the server
room. Springdale is here to stay and it finally got some attention due to
the ill-fated CentOS.

In a case, you wonder a CMU guy with ten years of experience using
Springdale is yours truly.

Cheers,
Predrag

P.S. I was not touching GPU nodes at this time due to the fragility of
NVidia binary blob drivers and "deep" learning ecosystem. In my
experience NVidia driver will eventually get broken and then I will refresh
those machines. 14 out of 23 machines run older RHEL 7.9 clone. Those
should be eventually upgraded. We do have two other GPU nodes that run
Ubuntu 16.04. They are generally off-limit for most lab users. I have no
immediate plans to do any work on them.
