Main File server RAM upgrade

[Predrag Punosevac]

Dear Autonians,

I just beefed-up RAM (paid by Dr. Dubrawski) on the main file server
from 64 GB to 128 GB. If your home directories are located on
zfsauton2 or zfsauton3 you have notice a 10 minute blip while machine
was powered off. I apologize for the inconvenience but many people are
away from Pittsburgh and this is a good time to do this kind
disruptive maintenance.

Cheers,
Predrag
