Not sure of the o/s , i think
AT&T 4.0,2.0,3433 386/486/MC
NCR
i did a uname -v thats what it return , the unix box is about 15 years old need to increase a file system so i can dump some data. the filesystem is /data

hmmm.. if my memory serves me, NCR had its own unix... ufff, quite old. I don't think it can be possible (extend a filesystem), I think you should create a new filesystem in other disk, move the content (or part of it) to the new filesystem and then re-mount it with the old mount point.

Cheers.

You can't expand it.

You need to mount the disk as a new filesystem, and either move all data to that filesystem or mount it under the same directory structure as the one already existing (may not be easy/possible).

What application(s) are you still using there? could you perhaps move them to a newer machine/OS combination? it may prove to be easier than adding a new hard disk to that particular OS/machine, specially as you do not know what you are doing. (no pun intended).

Well if it was Aix4 or higher or hp-ux 10 , i would know what to do.

I'm trying to move the data to another machine , problem is i need to somehow create space to dump the data from the database.

Is NCR unix obslete?
I do not see why you can't allocate spaceeee.
thanks!!

AIX = easy fix!!

willct, um you might say NCR unix is obsolete. The last NCR box I saw was over 8 years ago and that was while migrating the app to Solaris x86. I highly doubt that you can increase the filesystem.

If you are just trying to export the data to move somewhere else you might have some options. In the past I have used named pipes and rsh to export old Oracle databases. Something along the lines of:

create a fifo (mkfifo /data/exp_pipe)
prime the pipe (export_prog > /data/exp_pipe &)
let pipe get some data (sleep 10)
pump data to remote system (cat /data/exp_pipe | rsh remote_host "cat > /path/to/remote_dump")

This assumes that the export dumps to a single file.

That's a cool method. For sensitive data you could change that to ssh:

cat /data/exp_pipe |
ssh -l user remote_host "cat >/path/to/remote_dump"

Drop the -l user if you've got the same username on both machines.
