Main file server temp down

[Predrag Punosevac]

Dear Autonians,

The main file server Gaia is temporary down. I applied security patches and
updates across all the FreeBSD file servers and jail hosts (6 in total) and
rebooted them. Unfortunately, GAIA was running ZFS scrubbing and didn't
come back. In my experience, once the scrubbing finishes (hopefully in an
hour or two) it should automatically come back online. I apologize for any
inconvenience but servers need some regular maintenance to be able to run.

On an unrelated note, I had to reboot GPU2 which was crashed by runaway
scripts. As you probably know Python is not designed for scientific
computing and has a global interpreter lock (GIL) which makes multithreaded
programming almost impossible. Our users just like all other people who are
using Python for scientific computing keep spawning process in order to
fake multithreading as a result we have regular server reboots/crashes.

Cheers,
Predrag
