"UNKNOWN" problem, with a return code of 0 in solaris 9.

[Patrick Walentiny]

You're correct in saying that it is strange output.  It is explainable
though.  It outputs that because we're running a volume manager.  I
haven't looked to verify it, but I believe the other numbers are output
from the other plexes that make up the total volume that is each
partition.
	It does still remain though, that when I give it data that is
supposed to fail (on command line) it does fail, and when in a condition
that it shouldn't, it doesn't.  It is ONLY in the nagios process itself
do these plugins return UNKNOWN, even the output shown on our website
says the disks are ok.  It just says the state is UNKNOWN.

Pasted from our nagios website....

also note that this particular Solaris 9 host is not running veritas
volume manager, but still suffers from the same problem.

Unfortunately I'm not going to be much more help as I'm not too familiar
with the internal functioning of the plugin but the output you're seeing
looks odd to me, particularly the ";| /=10943MB;9606;10807;0;12008
/usr=6814MB;6452;7258;0;8065 /var=7875MB;6452;7258;0;8065
var/run=7437MB;5949;6693;0;7437 /tmp=7437MB;6028;6781;0;7535
/u01=426986MB;390857;439714;0;488572". I don't believe that's supposed
to be in there and it may be a result of df providing output in a format
that the plugin doesn't fully understand. It may also just be an
artifact of running check_disk under solaris and perfectly normal.
