dd if=/dev/zero bs=1m | mbuffer -m 64m -o /lsi/bigfile

with mbuffer reporting the following

in @  697 MiB/s, out @  697 MiB/s, 11.8 GiB total, buffer 100% full

when I pull the cable. Playing with it today, I'm wondering if the
1st cable actually has any active providers on it (luck of the
draw that I pulled it first), and the 2nd has all the active
providers on it.  I have not explicity tried to balance the i/o
on the two cables with gmultipath rotate.

Having a bit of trouble getting a good objdump of g_multipath.o
so I may do a new src update.

I had to do a wad of changes at Panasas to cover this kind of case. I have had some troubles getting these changes into -head (lack of time, differences from the RELENG_7 code I was working with, etc), but I think that there are still issues at play here.
