how to use more disk space

Status:
We are using firewall cyberguard running on dynosaurus SCO unixware 2.3.1.
As any old OS, it doesn't support more than 2Gb file system size.
We are using a RAID 5 with 36 Gb available.
Is there a way to create more slices or to use more disk space once the OS has been installed?
Thanks

Possibility:

1) Use ulimit -f 4000000 to temporarily increase the size

2) vi /etc/default/login file, and increase the ULIMIT parameter to 4000000

These might work, I've not used SCO since the war though mind.

Please let me know if these were of any use.

I think it's a FS limitation, not a configuration problem.

You'd probably have to get an updated kernel to overcome this.

About all you can do is setup a bunch of 2 GB partitions and apply some tricky mount point scheme.

Remember, you can mount partitions on top of other partitions as long as you do them in the right order.

So for instance, you could have:

/home
/home/ftp
/home/ftp/pub
/home/ftp/uploads
/home/www
/home/www/graphics
/home/www/html
/home/www/html/test

all as seperate partitons.

Another thing you can do is create some generic mount points and use softlinks when needed:

/disk1
/disk2
/disk3
/disk4

Then suppose /home started getting close to full, you could move like /home/ftp to /disk1 and create a link called "ftp" in /home pointing to /disk1/ftp.

You should be able to create more disk slices with fdisk.  I think there might also be a nice GUI utility to build filesystems in the slices once you create the slices, but my UnixWare memory is hazy at best.

Considering that the software version of Cyberguard hasn't been supported for a while, nor has UnixWare 2.x, you might want to seriously consider moving to something newer!

If the project must cost $0, consider running OpenBSD on your existing hardware.

Otherwise, for still not very much money you could go with one of the low-end appliances from Intrusion.com, Netscreen, or even Cyberguard.

Oh yeah, and another thing....

Since this is a firewall, why would you possibly want more usable disk space anyway?  The only thing I can think of is for logs, but if you have more than a few hundred meg/day of logs you shoulnd't be running such a dinosaur firewall.
