You can also configure any standard (distribution shipped) syslog to log
remotely to your head node or even a seperate logging master.  Anything that
gets reported to the syslog facility can be reported/archived in this
manner, you just need to dig into the documentation (e.g. man syslog, man
syslog.conf, man 5 syslog, etc) to figure out the configuration you need.
It is actually pretty straight-forward. Logging the I/O errors or any other
kernel driver output should be no problem.

Most standard syslog mechanisms will not let you cleanly create a hierarchy
such as what syslog-ng will give you, but I find that simply grepping one or
two central log files works better for me, anyways.
