This is simply a problem of one of your hd's detaching:

And so g_stripe passes the error to ffs and ffs panics because it
can't handle the write error... I'm not sure if there is work to
make FFS handle disk departers sanely or not...
I've heard that some cables can be bad, if it's the same drive that
keeps detaching, try replacing that cable...
It could also be a bad drive, I have a pair of drives w/ the same
firmware, and one would like to detach itself every month or so, but
the other drive runs fine... I know it's the drive since I hotswap
them, and they both have been in the same bay and it's still the one
drive that disconnects...
