How to fix quota not working in Virtualmin ?
Following are some of the steps to follow to handle this error.
1. Checking the configuration
- We can perform a re-check on the configuration file when we find an issue with the disk quota. This will help us to confirm the issues with the services in Virtualmin.
- The re-check can be done from Re-Check Config in the System Settings.
- Generally, if there is an issue with the quota, it will return the following output:
- Quotas are not enabled on the filesystem / which contains home directories under /home and email files under /home. Quota editing has been disabled.
2. Restarting the quotas
Another way to fix this error is to restart the quotas. As the re-check output will not always give us the exact reason for this error. In such cases, we can try restarting the quotas with the following command:
/etc/init.d/quota restart
We can also try restarting the Webmin service with the following command:
/etc/init.d/webmin restart
The restart of the quota service should give us clues on the issue like the one given below:
/etc/init.d/quota restart
* Turning off quotas...
quotaon: Cannot stat() mounted device /dev/root: No such file or directory
3. Symlink the /dev/root
If we get the error shown above after restarting the quota, we can infer that the /dev/root does not exist.
The device /dev/root has to exist and it should be a symlink to the partition on which the root filesystem resides.
So if our root filesystem resides on /dev/sda1, /dev/root should be a symlink that points to /dev/sda1.
We can find this using the following command:
$ cat /etc/fstab
If it is using the file system /dev/sda1, we can use the following command:
$ ln -s /dev/sda1 /dev/root

Conclusion
This article covers methods to fix Quota not working in Virtualmin for our customers. In fact, Quotas are used to limit the amount of disk space a user or group can use on a filesystem. Without such limits, a user could fill up the machine’s disk and cause problems for other users and services.
How to install Quota Tools on Ubuntu ?
To set and check quotas, we first need to install the quota command line tools using apt. Let’s update our package list, then install the package:
$ sudo apt update
$ sudo apt install quota
You can verify that the tools are installed by running the quota command and asking for its version information:
$ quota --version
How to enable Quotas on Ubuntu ?
Before finally turning on the quota system, we need to manually run the quotacheck command once:
$ sudo quotacheck -ugm /
This command creates the files /aquota.user and /aquota.group.
- u: specifies that a user-based quota file should be created.
- g: indicates that a group-based quota file should be created.
- m: disables remounting the filesystem as read-only while performing the initial tallying of quotas. Remounting the filesystem as read-only will give more accurate results in case a user is actively saving files during the process, but is not necessary during this initial setup.
