[Samba] Limiting User Space on Samba Share

[daniel.jarboe at custserv.com]

Not sure about samba 2.2.3a, but the quota support IS in RH 7.2 w/
redhat kernels.  I started using this last week with samba 2.2.6 and
this week with samba 2.2.7 :).  But it IS on a user-level per
filesystem.  So if you have one filesystem on a partition, and set up a
user quota of 100MB, once the user owns 100MB of files total anywhere on
that partition/filesystem they cannot write anymore to that filesystem.

If per-share quotas are really important to you then I suppose you could
create more partitions/filesystems tailored to your needs, but there
seems like there should be a better way... anyone know?

Btw, the --with-quota is a very cool feature that the NT/2000 servers
don't seem to do (unless the ones I've accessed are misconfigured).
Mapped to their shares I get space available all over the map though I
have a fixed quota... mapped to samba share I get space available
exactly what is remaining in my quota.  It looks much better.

Samba can't do it, but you can use filesystem quotas in the underlying
OS to limit users' disk usage. The one shortcoming is that it's not done
by share, it's done by filesystem. So if you want to control (for
example) people's user directory sizes on a /home filesystem, it's easy,
but if you have one big /export filesystem with a dozen different shares
all accessible by the same users quotas can't do what you want.

As I recall, Samba has a quota compile-time option that will check the
filesystem quotas and use that for the free-space display when users
check the properties. Not necessary, but useful.

I think RH's stock kernels have quota support enabled. If you're using
Red Hat's bundled Samba packages, I think those have the quota support
I mentioned above compiled in too. You will need the RPMs for the quota
tools installed, I think the RPM is just "quota" or "quotas".
