Quotas not working on new Virtualmin hosted server

Table of Contents

Background

You’ve just deployed a new Ubuntu server, but Virtualmin Quotas are reported as not active.

On some hosted Ubuntu servers you have to install the kernel sources, and reboot, before quotas will work.

apt-get -y install linux-image-generic

At this point it’s worth just trying again. If in Webmin you get this:

Failed to turn on quotas : quotaon: using //aquota.user on /dev/sda1 [/]: No such process quotaon: Quota format not supported in kernel.

Just try again.

Then try this:

apt-get -y install linux-headers-generic

Additionally try this:

apt-get -y install linux-image-extra-uname -r

To get quotas working with Virtualmin and XFS, two items needs to be present:

> cat /etc/fstab

/dev/mapper/centos-root / xfs quota,attr2,grpquota,usrquota,inode64,relatime,rw 0 0

> cat /etc/default/grub

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet rootflags=uquota,gquota"

To activate the GRUB changes, do this:

grub2-mkconfig -o /boot/grub2/grub.cfg

On GCP, this was the breakthrough, first install it then reboot

sudo apt-get install linux-modules-extra-gcp
