By extension, a logical question: Has Expiration been running? (In a neglected 
TSM server, it might not be, and getting that going could free a bunch of 
space.)
If Expiration has been running, a recourse is to go looking for obsolete nodes 
and filespaces to dispose of.

If your system has USB, you could conceivably plug in some inexpensive random 
access media to constitute a temporary storage pool to be able to initiate 
reclamation. NFS mounting is another way to get space.
