I have calculated a negative diameter for the pie chart, maybe your labels are too long or the picture is too small.

Hello Alexey Z and thanks for your detailed report,

unfortunately I need more data to reproduce and fix this problem. I had write a script for gather this data and attached it to the ticket. It is 'DiskUsageDump'. Please, download it to your system, execute it and report the results.

To run it, use this command:

sudo perl DiskUsageDump

Regards,

Javier

Hello Alexey Z,

thanks a lot for the data, I have made some changes in [d6f9f1fd45f7699] which I think will avoid this errors.

However we plan to change the sued graph library to have better and more reliable graph generation.

If you want to hotfix your server:

1) Download the new diskUsage.pm file fromhttp://git.zentyal.org/zentyal.git/blob/d6f9f1fd45f7699f84da65fba075a90c3624bcbb:/main/core/src/EBox/Report/DiskUsage.pm

2) Use it to replace /usr/share/perl5/EBox/Report/DiskUsage.pm

3) Execute 'sudo /etc/init.d/zentyal apache restart'

Regards,

Javier
