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.<br>
<br>
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.<br>
<br>
Thanks!<br>

ogvjs-testing for ongoing work on the mobile side (the

trim its disk space on my end. (It uses a lot of space
because it's got local copies of some videos from Commons,

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 :)<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
Thanks for your attention!<span><font color="#888888"><br>
