That warning about my sendmail is not a joke, I haven't come arround to
fixing it.

Hi Alan,

Thanks for trying to help me..

About my system...
It's a standard Slackware 7.1 install, except for Samba wich I recompilled
after configuring with the option --with-quotas. It uses a kernal version

My kernal does support quotas:
I added a testuser an gave him a (small) quota, soft 100k hard 200k and at
first no grace period. Later I added a grace period off 1 day which had no
When I log on as that user (bash) and add files (copying a certain
file) the quota manager jumps in at a certain moment and prohibits me to
create any more files.

So I think my kernal supports quotas.

Before I recompilled samba the following happened on a NT4 WS:
I could happely create files in the home share (which has the quota),
after I exceeded the quota files would be created off zero size.

After I recompilled (samba) this behaviour changed:
I could happely keep on adding files in the share, even when the quota is

I do agree with you, samba has nothing to do with the quota as it is.
But... it does strike me as odd that samba happily writes files while th
equota  is exceeded. How does it do that use root priveleges to write the
files. As root I was abble to copy files in the full directory.

Wouldn't samba at least not write the file and warn the user that there is
a problem with creating the file (disk full warning or such?)

Tomorrow I'll try to gather some details for you when I'm at work.
