Issue wrong Disk usage (possible because Mailman)

[Janko1000]

Hello Folks,


we have some Issues with one of our Customers.
The Customer use Mailman Mailling List and the reported used Space is possiblewrong.
The Mailling List has a Size from 5MB and the if we count alle Databases, Webspaces and Mails togheter we come to ~1GB.
But.... Plesk reported 5GB used and 90% from these 5GB are by Mails.

How can we check it?

Thanks for advice

How are you counting the usage?

Hi,
per Hand...
The Customer has only one Database and 4 Mailaccounts.
We count it via "du" and PHPMyAdmin.

It is possible that small files and databases occupy more disk space than what their content suggests, because disk space is not assigned bytewise but in segments of n bytes. The size of that block depends on the hard disk configuration. For example if a file only contains a single byte it might still occupy 4K on the disk. The same applies to database tables.

Hi Peter,
i know it but the Discrepancy is to high.

We cant explain this the Customer.

Have you tried to check the actual disk space usage by decending into
/var/qmail/mailnames
and running du on the customer's folder, e.g.
du -h <domain name>

Hi Peter,
yea we checked it.
We cloned the whole Abonnement to another Plesk Server... and what should i say...
The second Screen is similar to our Calculations.

You had initially reported this:
"Plesk reported 5GB used and 90% from these 5GB are by Mails."
and
"> we count alle Databases, Webspaces and Mails togheter we come to ~1GB."
From these two lines we can conclude that you believe that Plesk reports that 4 GB are occupied by email boxes on the server while they are not. So the task is to find out why Plesk reports an additional 4 GB of disk space usage that you believe are not really occupied.

Have you tried to check the actual disk space usage by decending into
/var/qmail/mailnames
and running du on the customer's folder, e.g.
du -h <domain name>

... was the polite way of saying:
"Please descend into /var/qmail/mailnames and run
du -h <domain name>
on the customer's folder, then please post the result here.

Users frequently focus on "it does not work right" and try to prove their point. We all believe that you are experiencing the issue that you are describing. But proving the point does not help to resolve it. You need to exactly test what the real disk space usage is. Once we have seen what the operating system reports as disk space usage for your mail box and then see that there is a discrepancy what Plesk reports as the disk space usage of your mailbox we can try to find the cause.
