mount problems

[Bob Hilliard <hilliard@flinet.com>]

     I have a spare machine that I am trying to set up for backups
using an ethernet net.  

     One partition (a bo system) has root mounted on /dev/hda3.  If I
login to this machine, and try to mount another partition, using:

     sudo mount /dev/hda4 or sudo mount /dev/rex

I get the response mount: /dev/hda4 already mounted or /rex busy.
However, df, mount and /mtab all show that /dev/hda4 is not mounted.

     The /etc/fstab file inclides this line:

/dev/hda4      /rex      ext2      defaults,noauto     0    2

     Any ideas for where to look for the problem?

Bob
