[cobalt-users] [RaQ 4] Active monitor states disk usage error

[James Stewart <bulldogs@xxxxxxxxxxx>]

The error is when I load the control panel interface for my raq, the
active monitor states a severe problem with 'disk usage' but when
clicking on disk usage all sites have green lights stating no problems. 
The most disk space used by any virtual site is 11%.

I searched through all the archives and there are limited instances of
others having similar problems. Some people suggested this error happens
because someone has hacked the server.  Others state it happens because
of disk space problems that don't necessarily show up through the
control panel.  However; I was unable to find a clear solution, or way
to find the exact problem.

Running: df -a as suggested in one place yields but I dont understand
the results:

Filesystem           1k-blocks      Used Available Use% Mounted on

none                         0         0         0   -  /dev/pts       

97% use might be the problem??

Any solutions?
