Overview

The quota of a domain on your Kerio Connect server is showing more storage used than its accumulated users' quotas. You may be wondering how you can fix this, for example by forcing reindexing of domain quota.

Solution

This issue could be as a result of a glitch in the Kerio Connect Webadmin, or the user quota being displayed incorrectly. In order to progress, please first take the following steps to check the disk usage and quotas:

1. Check the actual disk usage of the domain

• Run the following command: sudo du -sh /opt/kerio/mailserver/store/mail/<domain_name>
  • Where /opt/kerio/mailserver/store/mail is the default mailstore store directory, and <domain_name> is the domain in question.
    

    This will display the exact disk usage of the domain. If the domain quota is almost the same as the folder size of the domain, it could be an issue with the Webadmin UI. 

2. Check the domain quota

• In the Webadmin UI, navigate to Configuration > Domains > double-click on the domain in question > Quota

3. Check the users' storage quotas and usage for the domain

• In the Webadmin UI, navigate to Accounts > Users. Select the domain in question. Click the drop-down arrow and ensure 'Storage Quota' and 'Storage Usage' are selected, as shown in the screenshot below.
  

See if the results of the above 3 steps reflect something like below:

• Step 1 - the command calculates space as, say, 69 GB
• Step 2 - Webadmin domain calculates quota as, say, 77 GB
• Step 3 - Adding up all the quotas, you get say, 61 GB - which is lower than the quota calculated in step 2 (77 GB), and is also within the space calculated in step 1 (69 GB).

If you get results like the above, this could indicate that the user quota is being displayed incorrectly.

To resolve, follow the process in User quota is displayed incorrectly in Webadmin to reindex the storage quota usage for all users in the domain in question. In doing this, the Kerio Connect server will also be restarted, which might help in resolving the issue if it is caused by a glitch in the Webadmin UI.

If the issue persists, kindly open a support ticket and provide the following information for further investigation:

• Support Information file
• Screenshot of step 2 (in above example, showing 77 GB).
• Screenshot of step 3
• Screenshots of the domain quota, similar to the screenshot below: 
  • In the Webadmin UI, navigate to Configuration > Domains > double-click on the domain in question > Quota
