I forced a filesystem to be 100% full. I am able to generate a message to STDOUT:

# dd if=/dev/urandom of=reallylargefile count=2097152
dd: writing to `reallylargefile': No space left on device
1018761+0 records in
1018760+0 records out
521605120 bytes (522 MB) copied, 73.9457 seconds, 7.1 MB/s

But I cannot find it in any of the logs (/var/log/messages etc). Where are these events registered? dmesg also does not indicate anything. Do I need to up the verbosity of syslogd?

cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.7 (Tikanga)

Thanks in advanced

If you don't have some kind of monitoring set up or some other service complains about missing disk space, it will not be logged.

    Thanks. Odd. Most (if not all) flavors of *NIX do this out of the box. Looks as though Linux deals with this differently.
