Dear everyone, 

this is not an important issue, but I'd like to ask anyway, 
just in case the solution was obvious: 

I've bundled three 4TB RAID boxes using GEOM::stripe into a 
single 12TB volume. I didn't partition it, I just created UFS 
on it using newfs (a "dangerously dedicated" volume). 
This is not a production setup, I'm just testing the hardware.

I thought "fsck" would be a plausible benchmarking tool. 

-bash-2.05b# fsck_ufs /dev/stripe/data
** /dev/stripe/data
cannot alloc 768053748 bytes for blockmap

***** FILE SYSTEM MARKED DIRTY *****

After a forced mount, the 12TB volume works fine. It just 
can't be fsck'ed. 

The machine is a dual Xeon/Nocona + i7520, with 2 GB of RAM, 
running FreeBSD 5.4-RELEASE with an SMP kernel.

Any ideas are welcome :-) 

Frank Rysanek
