Hi,

First things first: if /dev/ad2s4 doesn't exist, you should MAKEDEV it.

Assuming it does exist, it might be that you have to mount the logical
partitions that reside within the extended partition.  Try the same
command with /dev/ad2s5, /dev/ad2s6, and so forth (MAKEDEV'ing those
nodes first if they don't exist, of course.)

I'm not sure myself, and I'd be very interested to know if that is
indeed what needs to be done...

HTH,
