[OpenAFS] How do you reset max VolID in VLDB?

[Kim Kimball]

I recently got an error when restoring a volume, reported in previous 
emails.

The error indicated that there had been an error incrementing max VolID, 
and subsequent volume IDs are 3x what they were previously.

Does anyone know how to reset the max VolID?  There's no "pts setmax" 
analog in the 'vos' command suite.  Any undocumented utility, he says 
with fervent hope?

Thanks!
