[Clusterusers] keg/cellar update

[Wm. Josiah Erikson]

This isn't about fly exactly, but I think the overlap between people who
care about keg or cellar and fly is near-100%.

So, we have a new version of cellar (our backup server), which has 22TB
of space. Whoah. It's a hardware-controlled RAID6 of 6 6TB drives.
Because of this, I have started backing up everything - all of keg, and
all of fly, with a few exceptions that is just my stuff. This does mean
that the backups are taking a long time, particularly of fly, meaning
that they don't always finish in 4 hours and so we occasionally miss
one, so if you have anything that is truly temporary/junk that changes a
lot, like a huge scratch folder full of lots of files, let me know, and
I'll prune them from the backups. No biggie though.

So, that's great.

What's less great is that we may be the process of losing ANOTHER disk
in keg. However, this time we won't lose anything, even if keg dies
entirely, which probably won't happen, and I am in the process of
building a new RAID 6+2 16-drive keg that will have around 30TB of disk
space, and be much faster and more reliable as well. I hope to have it
ready to go by the end of next week.

Have a great weekend!
