How To Set Filesystem Quotas on Ubuntu 18.04 or Debian 9.

Quotas can be used on servers to set limits on how much diskspace an individual server user can take up on a server. They can be edited in the /etc/fstab file.

In order to enable quotas, first open the /etc/fstab file:

nano /etc/fstab

Within that file, edit the following line, adding in the word, “usrquota”:

LABEL=DOROOT	   /               ext4    errors=remount-ro,usrquota 0       1

Save and exit

The /etc/fstab file should now look like this:

LABEL=DOROOT       /               ext4    errors=remount-ro,usrquota 0       1
none             /dev/shm      tmpfs   defaults                    0 0

To finish up, remount the file system whose fstab entry has ben changed:

 mount -o remount /

Hi. I followed the guide here but I get this message. Is this cause for concern? I used it on a Centos7 machine.

quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown. quotacheck: Quota for users is enabled on mountpoint / so quotacheck might damage the file. Please turn quotas off or use -f to force checking.

My original fstab:

LABEL=DOROOT / ext4 defaults 1 1

Which I edited to

LABEL=DOROOT / ext4 errors=remount-ro,usrquota 0 1

Thanks in advance for the help.

You should run first the command: quotacheck -vagum -F vfsv0 this will create the quota files and then you can follow the following tutorial: http://serverfault.com/questions/37737/quotas-in-vsftpd

Any luck experts!

@paul.cherepnin: What’s the output of <code>sudo fdisk -l</code> and <code>df -ah</code>?


I’ve got the same problem…

Hi, I have followed he tutorial but I am facing issues. The following message comes if I run the command:

sudo quotacheck -vguma

quotacheck: Cannot guess format from filename on /dev/disk/by-label/DOROOT. Please specify format on commandline. quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.

My fstab is here:

LABEL=DOROOT / ext3 defaults,errors=remount-ro,usrquota,grpquota,barrier=0 1 1 none /dev/shm tmpfs defaults 0 0 /swapfile none swap sw 0 0
