We have an application which is precompiled, for linux, and stupid.
It uses (at times large) scratch files. We want to run this on our
diskless machines (CPU farm) to cut the per-cpu cost of the
computation ($200/drive starts getting significant at a few hundred
machines).
Anyways, I've tried:
[1:26:2025]root@spitfire:/usr/u/dgilbert> mount_mfs -T test -s 2097152 -o nosuid,nodev /dev/null /mnt
[1:27:2026]root@spitfire:/usr/u/dgilbert> df -k
Filesystem 1K-blocks Used Avail Capacity Mounted on
192.168.255.49:/raid/clients/4 124545452 87451588 27130228 76% /
procfs 4 4 0 100% /proc
mfs:57939 507755 1 467134 0% /mnt
[1:28:2027]root@spitfire:/usr/u/dgilbert> tail -5 /etc/disktab

:ty=removable:dt=SCSI:se#512:nt#1:ns#31:nc#18600:ts#1:rm#4800:\
:pc#20971520:oc#0:\
:pa#20971520:oa#0:ta=4.2BSD:ba#4096:fa#512:
The goal is to have about 2 gig of filesystem available for these
(admittedly stupid) scratch files.
Dave.
