 * the -current version to see what Terry's talking about.

Really?  The bcopy code hasn't changed for a long time, it's December
that it last changed.  I thought NFS was stable until pretty recently....

 * Au contraire.  So how big _is_ this filesystem?  I was being told by a
 * rampant Linux-fanatic genetecist the other day that "of the PC unices,
 * only Linux could possibly manage either of the HGI database, because
 * it's so big."
 * 
 * According to him it's around the 100GB mark; obviously you wouldn't

So how does Linux build a filesystem that size?  Do they have a
striped disk array driver too?

 * put this on one filesystem for performance/backup reasons, but it would
 * be very funny to counter his drivel... 8)

Well, we hit one limit at 128GB yesterday (32 x 4GB).  I modified
<sys/disklabel.h> to support disk numbers greater than 32 (more on
this later), and right now it's at 160GB (40 x 4GB).

We don't have any more disks right now.  But fear not, we're getting
40 more so I'll post here when we get to 320GB. :)
