HP-UX File Sizes

[Neale Ainscow]

Is it possible to place a limit on the maximum size of a file that a user can create in a filesystem?
e.g. If /tmp is 2 GB the user should be able to create 4 x 512MB files but not be allowed to create any file over that size.

Hi,

there is another thread on the exact same question going on at this time, take a peek at it.

Hello,

As far as I can read, I think this question is different from the one Eugene has linked to, in that you want to be able to write 4x512Mb instead of 2Gb whole.

My question is, why do you need this? You won't win any space on your harddrive by doing this. Is there any application which requires you to do this?

Hi,

"ulimit" should do the trick ;)
(please note that ulimit works with 512-byte blocks!)

Thierry.

Hi,

Try this,
ulimit -a shows all userlimits.
If [file] is not set to unlimited, this can be done additional with:
ulimit -f unlimited

If this is not set to unlimited, after the next reboot, it is recommended to insert
ulimit -f unlimited

into /etc/profile.

Hi Neale,

The answer to your question is yes. Use ulimit (man ulimit).

ulimit will affect every file the user creates in any filesystem. If the user has access to the shell then he may re-run ulimit thus defeating what you are doing.

Hi again,

I wrote man ulimit before I thought. ulimit is actually a shell built-in command. Use man on:

sh-bourne(1) Bourne Shell (/usr/old/bin/sh) description.
ksh(1) Korn Shell (/usr/bin/ksh) description.
sh-posix(1) POSIX Shell (/usr/bin/sh) description.
csh(1) C Shell (/usr/bin/csh) description.
keysh(1) Key Shell (/usr/bin/keysh) description.

Oops!

Hi,

Like others suggested ulimit.

I like to give some additiol information. The vxfs filesystems have a build in limit of 2 GB filesize, with can be overruled with the largefile option included in the mkfs command:
mkfs -F vxfs -o largefiles special size. Since your file system is 2 GB you do not need this.

The Question Author has not responded anymore, but it looks like he is more looking for Disk Quotas than for ulimit et al.

See the SysAdmin documentation or/and quota(5) and friends for details.
