Thankyou. The custom class ad is the conical way

yes, you are right. It is the `execute`

Is it possible to change this? I would like to use a different directory
(filesystem).

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:

TotalDiskSpace? At the moment its looking at CWD of condor_master

I thought it looked at the volume containing the EXECUTE directory, i.e.
it looks wherever
