I installed Virtualmin onto a Linode running Centos 6, but ran into some error.
Failed to create virtual server : setquota: Cannot stat() mounted device /dev/root: No such file or directory setquota: Mountpoint (or device) / not found or has no quota enabled. setquota: Not all specified mountpoints are using quota.
Check via ssh:
quotaon -p -a
That should return:
quotaon: Cannot stat() mounted device /dev/root: No such file or directory group quota on /home (/dev/xvdc) is off user quota on /home (/dev/xvdc) is off
This is the same error: This thread on Virtualmin’s forum
So lets get started on fixing this:
That should return
... /dev/xvda on / type ext3 (rw,noatime,grpquota,errors=remount-ro,usrquota) ...
Right, so our root / partition is indeed on /dev/xvda so we can create the missing symbolic link:
So run this command:
<strong>ln -s /dev/xvda /dev/root</strong>
That should return something like:
quotaon: cannot find /home/aquota.group on /dev/xvdc [/home] quotaon: cannot find /home/aquota.user on /dev/xvdc [/home]
Before proceeding, in /etc/fstab please be sure “usrquota” and “grpquota” are in the options line:
/dev/xvdc /home ext3 grpquota,errors=remount-ro,usrquota,grpquota,noatime,rw 0 1
Now, instead of going thru a dozen cryptic commands, go back to Webmin (if Virtualmin is up, click Webmin on the top line). Open the System tab and then Disk Quotas. You should see the /home partition listed, and it probably says that quotas are not active. Simply hit “Enable Quotas” and the display should change to:
|Linux Native Filesystem||Xen device C||User and Group Quotas Active||Disable Quotas|

This is best solution I have found regarding issue of Centos Quotas while using a Linode VPS.
I owe you a bottle of beer!!!
Hey Jolly! Glad I could help! Let me know if you have any other problems with CentOS on Linode – I will be glad to help!
This works fine, until you reboot the server. I haven’t found a fix yet …
Were you ever able to get it to work after reboot??
Just create the symlink to /dev/root for quota fix in:
Here is where /dev filesystem is populated on boot, so just add:
ln -s /dev/xvda /dev/root
Just before the “end script” line inside this file. That will do the trick…
Thanks for the advice on how to fix the Disk Quota issue on Linode running CentOS Virtualmin
