Well, since the execute directory is where HTCondor writes files when it 
transfers files on your behalf, this is the directory it looks at when 
computing free space.  You could change it to a different filesystem by 
simply moving the execute directory to a different filesystem and then 
either creating a symlink or changing the value of EXECUTE in the 
condor_config file (and restarting HTCondor).

Another idea: you can always publish any custom attributes you want into 
the startd ad, including "dynamic" attributes that change in value. 
Thus you could create custom machine attributes like DiskSpaceVolumeA, 
DiskSpaceVolumeB, etc, and use them in requirements and rank expressions 
to steer jobs to/from machines as desired.

See the Manual or, to get going quick perhaps these HOWTO recipes:
