quick quota setting?

davidstvz · 04-15-2009, 11:04 AM

I have a Suse Linux 10 system with quota already installed, but it is not enabled.

Is there a way to quickly enable a quota that is the same for all users?

If not, does anyone have a script that can set the same quota for every user on the system individually?

Use the setquota command using a loop over user names:

Code:

for name in user0 user1 user2 user3
do
  setquota -u $name W X Y Z filesystem
done

where W, X, Y, Z are the block-softlimit, the block-hardlimit, the inode-softlimit and the inode-hardlimit respectively. filesystem is the actual filesystem with quota. Then turn quotas on using the quotaon command.

What if I have to loop over several hundred user names?

Have you a list of them? Or can you retrieve all of them with a simple command?

If they are in a list (one username per line) just do

Code:

while read name
do
  setquota -u $name W X Y Z filesystem
done < namelist.txt

if you can retrieve them using a command, just do

Code:

for name in $(some_command)
do
  setquota -u $name W X Y Z filesystem
done

I should be able to generate a list from the passwd file easily enough.

So the only variables in that code I need to replace are W X Y Z and filesystem?

The size values are specified in bytes I guess. What is a reasonable number of inodes for a 120 GB partition? And filesystem refers to a partition? How do I specify it by device id? Like /dev/sdc1

Sorry to be such a noob.

Wait, I'm seeing some other stuff on the web. Do I need to edit the fstab and change the way the disks are mounted? I'm still confused here.

quota is installed by default, but it's not enabled. I guess I need to go into init.d and fix all that up. I'm not sure how to do that.

fstab should contain mount args usrquota (and grpquota if you need it) and they'll be used when the FSes are mounted. Since fstab takes quota args it seems reasonable to expect mountpoints, not devicenames. Take into account users don't have any business in say /boot, /usr (unless your perception of filesystems is severely skewed) so you could focus on areas where they do like /home and /var (mailspools and such). You could use the values of one "average" user to come up with "average" values for XYZ. One lame quck way to initialise quota (to get some values) could be to run 'quotacheck -cugamMf' but YMMV(VM).

Thanks very much. With your help and this page, I was able to reign in the singular user that caused the problem. On Monday I will use a script to get the rest: http://www.yolinux.com/TUTORIALS/Lin...ialQuotas.html

Thanks,
