Quota does not seem to be working

Hi Folks,

I'm using Red Hat Enterprise 5.4 and I'm trying to implement the quota on a new partition.
I practiced creating the quota on the /home directory was successfully and I now want to create a new directory mounted on a new partition and enable quota.

I created a new directory /data and mounted it on a new ext3 partition sdb3. Quota seem to be enabled but I just can't assign quota based on individual user. Can I set the quota on /data for individual user?

I dont believe quotas work for the root user... Try setting up with a normal userid.

have you remounted the /data filesystem?

also as stated above root might not use the quota.

hi jools,

That's the problem I have set quota for user but it is not showing.

I have entered the command:

setquota student 512 1024 0 0 /data

even tried

setquota student 512 1024 0 0 /dev/sdb3

When I tyep "edquota student", I can see that the parameter has been set but when I run repquota /dev/sdb3 only the root quota is shown.

Tried loging in as student and do a sudo but password is invalid. Strange but I don't think I need to login as student to set quota ya?

Just restarted the comp to be sure. I did what you mention but still no luck.
[root@example ~]# quota student
Disk quotas for user student (uid 507): none
[root@example ~]# quotao
quotaoff  quotaon   
[root@example ~]# quotaon -vug /data
quotaon: using /data/aquota.user on /dev/sdb3 [/data]: Device or resource busy
[root@example ~]# quotaoff /data
[root@example ~]# quotaon -vug /data
/dev/sdb3 [/data]: user quotas turned on
[root@example ~]# quota student
Disk quotas for user student (uid 507): none
[root@example ~]# setquota -u student 256 512 0 0 /data/
[root@example ~]# quota student
Disk quotas for user student (uid 507): none
[root@example ~]#

Any ideas guys? I really want to get this working.

I can reset to the snapshot since I'm using a VM. How about a step by step guide to set quota on /data on /dev/sdb3 and to check each step?

When you run quota username, you will only get responses when the quota is in soft/hard condition i.e. over the softlimit or over the hard limit when/if set.
To see the quota, use quota -v username
This will out put the quota information for the user without regard to their condition.

Hi arnold,

thanks. I see the quota when using quota-v username.

The problem seem to be resolved when I log in as student, cd to that directory and then dd a file size that exceeded the quota. When I run the quota command as student, the quota appears. At root repquota also shows its. Very weird.

I figured out some points which are important.
quotaon -vug /data //I tested with quotaon /data and it doesn't work. Switches is important
user must have permissions to the /data dir.

What is the output of the following code?

Hi tmaleshafske,

Apologies but I have shut down the VM but the code will show the quota of the user. One more thing that I found out. After applying quota on that particular partition or folder, I will have to log in as that user and copy a file in. Only then will the quota be shown.

I am missing something...

when I perform ::.
setquota myusername 400 1024 0 0 /home
I get this error

Mountpoint (or device) /home not found.
NOT all specified mountpoints are using quota.

run mount to see whether you have quota as an option on the /home volume
alternative look in /etc/fstab to see if quota is set as an option when mounting /home.

i.e. output from running mount
/dev/mapper/VolGroup01-LogVol02 on /home/ type ext3 (rw,quota)

fstab example:

device                   mountpoint              type                      options          dump fsck
/dev/VolGroup01/LogVol02 /home                    ext3    defaults,quota        0 0
