That happened to me some time ago, so here is my experience: The OS wont crash, but a hole lot of programs / deamons will stop working. I.e. syslog / klogd will complain that they can't safe to the logfiles. If you exit WindowMaker it will try to safe its preferences, wich of course fails and you will lose *all* settings from WindowMaker (good to have a backup). The same may be the case for *a lot* of programs. So: If your disk is full, don't touch anything. Free diskspace ASAP, then better reboot to restart all services. > as for my workstation, i am not as concered but would like to prevent a > fatal crash. > any thoughts? Most people recommend not to have one large partition, but more, smaller ones instead. Directories to put on its own partition: /tmp *any* user can write to /tmp and thus can fill up your HD within seconds. Just try dd if=/dev/zero of=/tmp/big_file as user nobody. /var or at least /var/log A mis-configured caching www or news proxy can collect GigaBytes of data in a few weeks (/var/spool). A faulty drive can fill up your logs in the gigabyte range pretty quick with error messages /var/log. This went through the list a few weeks ago. The guys /var/log/syslog was > 5Gb IIRC /home Any evil user can fill up your HD as easy as in the /tmp directory.
