disk quotas and how to fix them.

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.

Bumping this very old thread - I had fixed the issue using the above and it was working, but I noticed recently that I had lost my quotas.

After some digging, I realised that the disks are now called sda (and sdb, sdc, etc). The xvda device no longer exists.

So I deleted the logical link to root and recreated it pointing to /dev/sda

Also edited the rc.local file so it will now create the link correctly and quotas should work on a reboot

user@host:/dev# cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
ln -s /dev/sda /dev/root
/etc/init.d/quota restart
exit 0
