Quotacheck doubled quota in Virtualhost with chroot jail

Submitted by nikkio on Fri, 10/04/2019 - 05:05

Hi,

I've noticed that the Virtualhost quota is doubled after a quotacheck via the Virtualmin tool. In this way a lot of Virtualhosts are overquota but the effective homedir size is half the quota indicated by Virtualmin!

In these Virtualhosts i have enabled the chroot jail.

In Virtualhosts where chroot jail is not enabled, the quota count match the homedir size.

Can you post a screenshot showing the page on which the quota is doubled?

Also, what does the mount command output on your system?

looks like a bug that was present in ubuntu 16.04...i had this exact same problem.

Can you also post the output from the command grep quotas /etc/webmin/virtual-server/config

Submitted by nikkio on Sun, 10/27/2019 - 03:09

Sure,

home_quotas=/home
mail_quotas=/home
quotas=1
hard_quotas=1
show_quotas=0
show_uquotas=0
group_quotas=1

Submitted by JamieCameron on Sun, 10/27/2019 - 16:34

That looks fine to me (all quotas are on the /home filesystem).

Can you post a screenshot of the page on which the incorrect quota usage is shown?
