My particular disk-full condition was on ext2. Nothing exotic. Also,
the process that filled the disk was postgres - if that makes any
difference - I had left a debug level turned up in the postgres config
file, and it was logging every single db query. Since it wasn't set
up to remove old log files - it filled the disk.
Nothing else unusual occurred that I'm aware of - things went weird
for the lab tester, he cleared some space, rebooted the system, and
postgres didn't come back online.
