Since the latest docker update (Version 2.3.0) I receive the following error in my mailbox:

06:11:01 WARNING   [php] Warning: Division by zero ["exception" => ErrorException { …}]

Same issue here

Also after the update to Version 2.3.1 I still receive the same error

We’ve got the same issue. The problem is related to the filesystem - we use BTRFS which returns 0 as free inode value - thus the division in getFreeInodes() fails.

$ df -i
Filesystem     Inodes IUsed  IFree IUse% Mounted on
/dev/sda2           0     0      0     - /

Our temporary fix is to remove the getFreeInodes() call from the code:

sed 's/$s->getFreeInodes();/1;/g' -i /opt/admin/src/Base/Command/CheckFreeSpaceCommand.php

I guess the function should deal with such a return value…

Same issue here, also running on btrfs

Should be fixed with #899 https://bitbucket.org/analogic/mailserver/issues/899
