Pseudo-disk Driver
Wanted: Pseudo-disk Driver
Reply-To: Lee.Moore@cmu-10a
Description: What I am trying to find is the analog
to the pseudo-tty driver. The effect I am trying
to achive is to be able to mount a filesystem across
a network. It seems to me that the best way to
do this is to have a pseudo-block device that
has two ends. A regular end that is given to the mount
command and a control end. The control end
would receive low level commands such as read or write
block. The process on the control end
could then forward the requests over a net.
If this is not clear, please
send me a note and I will try to elucidate.
[Historical note: I originally saw a version of this at the
National Bureau of Standards where the remote
filesystem resided on a PDP-10 (as one large file).
It was faster to use the '10s disk than RK05s.(!)
Unfortuately, this mechinism was tightly bound to the device
driver for the link.]
Many Thanks,
Lee
