Hi all, I would like to enable dis quotas for my server and this is what I did so far. so, I have installed quota by doing apt-get install quota and all is working there. now here is the funny part. I have used webmin to get everything configured for disk quotas even getting them ready for the /dev/xvda device. but when I go to enable the quota in the webmin modules it doesn't do it... Further more, I can't run my quota check -a command because it would just say, "unable to stat /dev/root, no such file or directory." Does anyone know how I can fix this. I'm running ubuntu 13.10 and I have read and herd that this is a ubuntu bug that's not suppose to happen. Everything is configured in the /etc/fstab file as expected and boots perfectly. so what would I have to do to get my disk quotas to work properly? thanks all.

If I am remembering correctly you need to boot a custom kernel to have quota support. The pre-provided Linode kernels do not have support for quotas.

Add the following two lines to /etc/rc.local, right before 'exit 0' :

# /etc/rc.local

ln -s /dev/xvda /dev/root
/etc/init.d/quota restart

exit 0

That allowed me to start quotas in Webmin, and also have them persist after a reboot.
