You don't have enough free space in /var/cache/apt/archives/

[ka...@oakland.edu]

The var folder of profile is set to 16GB. I am out of more space. I am trying to install some packages, but I got an error "You don't have enough free space in /var/cache/apt/archives/". I freed up all deb files, and still not enough. Can I increase var size? or I have to create another profile or experiment that allocates big partition for var folder (which one do you recommend?)

How much software (roughly, in GBs) are you planning to load? And are you
planning to make a custom image of the result?

Creating custom images over about 10-20GB become unwieldy as our imaging tool
is best suited to images that are loaded on multiple nodes simultaneously and
that have filesystems that are not densely populated. That is, it wins by
multicasting and by understanding the underlying filesystem and not
saving/reloading unused space in that filesystem.

I need to install libvmi. First, I need to install some dependencies that require about 2-3GB in archives folder.

Hi. Unfortunately, you cannot expand the root filesystem, but there are
other unused partitions on the disk that you can initialize and mount
as needed. There are several ways to do this, but it depends on how the
space is used. Is it just extra space to build libvmi? I ask because the
dependencies listed on the web site for libvmi do not seem to indicate
that it needs 3G for dependencies.

The easiest thing to do is:

sudo /usr/local/etc/emulab/mkextrafs.pl /somedir

Caveat: you cannot take a snapshot of this space, only the root partition
is saved when you take a snapshot. But in this case that is okay, since you
cannot take snapshots of any nodes in an OpenStack experiment.
