Have a look at this technote:

there are some useful commands in there for managing WSUS, esp the deleteunneededrevisions which "Purges the update metadata for unnecessary update revisions from the database."

But this is only a short term solution. I would extend the partition to give it more space or move the store elsewhere.

That link has all the command you require for these options.
