We added a couple of new extra-large nodes to the eqiad virt
cluster at the end of last month. They've been performing fine, so this
week I'm going to do a bit of re-balancing. I will be moving a few
instances off of overloaded servers (virt1002, virt1005, virt1009) and
on to the new, empty servers.
In most cases you won't notice these moves -- migration will cause
a few-minute freeze on the instance but will not require a reboot. On
occasion an instance doesn't survive the move intact and needs a reboot
afterwards. If you have an instance running on one of the above hosts
that cannot survive a 10-minute interruption, please let me know;
otherwise, no action is required on your part. I don't plan on moving
any tools nodes unless absolutely necessary.
Note, also, that the addition of these servers means that our space
crunch is largely at an end. If you need a quota raised and we've been
putting you off, now is the time to re-ask on IRC :)
