Testing that the file /sbin/quotaon exists, then execute the command....

Take another look at the procedure below.... The "quotacheck" command
with a -c option, will create the aquota files.... Take a look at "man
quotacheck" for more details....
And yes, unless the whole procedure has been followed, there is no quota
limiting....

Of course your other choice is to reboot.... :-) But the remount option
has worked pretty good.

One last thought for you.... I generally do not find much need to set a
quota on the "/" filesystem. On a truly multi-user system (implying a
need for quotas), I ensure that the regular user writable filesystems do
not include "/". I generally have a separate /home, /tmp, etc.... I
can then place a quota on those filesystems only. I also never put a
limit on the user root......
