[Casper] Best way to check disk space on /Volumes/Data?

[Thomas Larkin]

You can use the du command, but mind you it takes a while to scan the whole drive.  You can option out for it to only show the top level directories and their files sizes and such. 

A much lighter load would be the df command which would just display the volume names and the total size, where as the du command would be more in depth.  A while ago I wrote a script for basic diagnostics and published it on OSXhints.com which had a command or two to check disk space, you could take my code and rewrite it if you wanted to.

Hi Folks,

We've gone to using three partitions for our machines: Restore, 
Macintosh HD, and Data.

     Restore contains the Casper Restore partition.
     Macintosh HD contains the OS and applications.
     Data contains the User home folders.

I know I can track free space on Macintosh HD in the JSS, but what's 
the best way to check the space on the Data partition?

I've gotten as far as writing an AppleScript to test the free space on 
the Data partition. I have an arbitrary threshhold of 90% full as my 
warning level. The script will return TRUE if the Data partition is 
90% full or greater, it returns FALSE otherwise.

Where I'm running into a problem is figuring out how to take this 
information and create a Smart Group containing machines whose Data 
partition is 90% full or better.

I've seen some references to installing dummy packages, then creating 
Smart Groups based on whether a particular package is installed.

Is this the way to go, or is there a better way?  And if this is the 
right way, is there a good reference on doing this?
