Hi DU Admins
My question was about NFS mounting the /dev directory from one
machine onto another to get access to the tape drive on the first.
The unanimous response was that this doesn't work. After reading
the replies and thinking about this it's obvious that it can't
work. What fooled me was the man page for mount(8) which says
about the dev option:
dev Allows access to block and character-special devices.
This made me think it might be possible. Just dreaming.
Thanks to alan_at_nabeth.cxo.dec.com, James Sainsbury and Drake Callahan
for their swift replies.
James suggested using ssh doing something like:
dump 0f - /dev/rz0a | ssh dumphost /bin/dd of=/dev/rmt0a
We are running ssh here so that would be easy to do. I was hoping
not to have to do it that way. (I would specify a block size larger
than the default 10k for this).
He also suggested having a look at amanda:
ftp://ftp.cs.umd.edu/pub/amanda
Drake suggested doing it the other way. That is nfs mount the
directories to be backed up onto the machine with the tape drive.
I don't think this works either. The man page for dump seems to
me to imply that you have to give it either the name of a local
file system or else a device name.
I believe there are versions of dump which will dump arbitrary
directory trees but not the Digital Unix dump as far as I know.
Cheers
Ian
