Ah, now that I look more closely at the backtrace, I realise that 
creation succeeded, but it is now failing on subsequent runs because it 
can't find the metadata pool.  I guess you probably deleted it at some 
point between Monday and today.  You will need to create yourself some 
filesystem pools (metadata and data) before using newfs to reset your 
filesystem.

Cheers,
John
