@Squid - thanks so much for the help. I was able to easily expand the vdisk, and was then able to update all of my docker containers, so, problem solved for now. That said, I didn't see anything that stood out as a container significantly larger than the others, though 8 of my containers are over 1GB in size, while the remainder are under 500MB. Does anything in the attached look off to you, or do I just have quite a few containers, and just needed a bigger vdisk to accommodate, so I am now ok? Thanks again.
