Good, but workarounds aren't that nice ;-)

Before we think too far, could you make a diff of your different nrpe.cfg's?
Maybe you include another file in which the command check_all_disk is
defined a second time?
That would be a simple explanation...


What happens if you add a sudoers entry to allow the nagios user (or the
user you're running the nrpe daemon as) to launch check_disk? Modify the
check_command so you use sudo before the check_disk command.
