This is why I stopped using physical partitions and LVM instead entirely.

If you fill your physical partition, it really doesn't like it, and all
hell breaks loose, as you see.  Boot from a boot cd, clear some space, and
reboot.

Start with "sudo du -h --max-depth=1", figure out what is filling your
disk, and delete some.  Reboot.  Usually logs, updates, packages, etc cruft
- kill it all.

When it's sane, move to a more agreeable FS structure, use LVM, I can fill
a disk and stay up, much less impact if/when this occurs.

I break /var and /var/log into separate partitions always, these are
typically what fill and break.  Keep them separate with LVM's, much happier
to recover if any one fills up.  I normally keep /usr with debians separate
too, but arch installs hate this.  Also I keep /home separate, as I fill
this commonly, which breaks anything running in userland if/when occurring.

Funny, I do this because this is how we installed solaris this way with
slices like +20-some years ago to not blow up, but over-simplification
these days ignores fun facts like these.
