I've tried doing this, but the server never tells the clients when the
quotas has been reached. I can run quota(1) no problems, but if I have a
5mb quota on a directory and I try to write more than 5mb from the client,
the client *thinks* everything went just fine. Meanwhile, the server
just stopped writing data at 5mb.
Can you run a really quick test on your setup to verify if I've done
something wrong ? Set up a small (<10mb quota) on the server. On the
client, run a little perl program like this :
--START--
#!/usr/bin/perl
#
for( $i=0; ; $i++ ) {
print "This is test line $i\n";
}
---END---

At the same time, run a 'tail -f' on the same file from the server. When I
did this, I could watch the quota go up from either machine. The tail
process showed new lines being added (the increasing number obviously
being the indicator. However, when the quota limit was reached, the
client never knew. It just kept on writing happy as can be. The tail
process just stopped. No new lines were being committed to disk.
If your results differ in this respect, I'd really appreciate knowing. At
least then I know it's possible, and that I can with effort get it to
work. If not, I have to re-think what I'm trying to do.

Agreed.
Thanks again for your help.
