Blocks and files... there are quotas for both ("blocks" is the amount of space; "files" is the number of files).
Disk quotas for user wby (uid 31964):

The NFS thing makes it confusing because you'll see quotas set on mutlple filesystems - they should all be identical, though.
Note that "quota" is the hard quota, not the soft quota. We don't actually enforce soft quotas other than to charge you for exceeding them.
