Hello,

Due to the lack of enough "networking power" I started to think about
alternatives.

I would like to ask your thoughts on the following setup:

         +----------+       +----------+      +----------+
         +   BOX1   +-------+ SCSI BOX +------+   BOX2   +
         +----------+       +----++----+      +----------+
                                 ||
                            +----++----+
                            +   BOX3   +
                            +----------+

BOX[1-3] would be a PC with a SCSI adapter. SCSI BOX is an external SCSI
RAID array.

The line between the boxes is a single SCSI cable, on which the devices
access the bus (it would be a correct chain, with a terminator on each
end).

The question is:
what will happen if BOX3 mounts the filesystem from the SCSI BOX RW and
BOX[1-2] mount it RO?

In the case BOX[1-2] it is only necessary to read from the array, nothing
more.

I've seen a similar setup on Sun hardware, where the disk array was used
by two computers. RW/RO, as in this case.

Does anybody have experiences regarding this? Is it possible/necessary to
hack some kind of locking into the SCSI driver? The adapters are made by
Adaptec (aic7xxx).

Thanks,
