Huh. WDQ seems to be the biggest problem, but I can't find the data -
only ~20GB in total.
I'm not 100% sure about how our qcow2 setup works, but I suspect that if
the storage use of an instance grows and then subsequently shrinks the
new space is not automatically reclaimed. So if you see specific
instances that are huge on my report but small in reality, I can reclaim
empty space by shutting the instances down briefly and recompressing.
Magnus (and, really, anyone) if you find cases like that please let me
know the instance and project and if/when you could tolerate downtime
for a few minutes.
Thanks!

Unless Yuvi has cleaned up in the meantime, or I don't have permissions...

Thanks for the reminder ping! I still need ogvjs-testing for
ongoing work on the mobile side (the desktop integration is done
months ago) but I can probably trim its disk space on my end. (It
uses a lot of space because it's got local copies of some videos
from Commons, but the player can pull them directly from Commons
these days.)

Disk space is always the most limited factor on the Labs
virtualization servers. If you're using it for something
good, then no one minds! If you're using it for logfiles that
no one ever reads, or using it for instances that have
long-since been forgotten and no one cares about, then I mind
a little bit :)
Attached is an epic list: Every instance, sorted by disk
footprint. Please take a moment to hit ctrl-F and scan the
list of instances that you created or that are part of a
project you work with. Look at those instances, and ask
yourself if they would be missed.
If the answer is 'no,' please delete them! Or, email me
and I'll delete them. (Actually, even if you delete them
yourself, I'd appreciate knowing about it so I know whether or
not emails like this are useful.) If the answer is 'maybe'
then please call my attention to the instances in question,
and I'll do the necessary pestering and verifying to determine
whether or not they can be safely deleted.
Benefits of good VM hygiene include: Less
rebalancing-related downtime, better VM performance, happier
operators, and more money for the Labs team to spend on
things more interesting than storage space.
Thanks for your attention!
