Thanks. As a final note for completeness and clarity, the circle graph of local disk space on the Dashboard should show the percentage of space used relative to the root filesystem. That filesystem is correctly identified as “/ (Root filesystem) ZFS zroot/ROOT/default” on the Disk and Network Filesystems page of Webmin, but the circle graph now always displays 100% as the local disk space used on “/dev/vtbd1” mounted as “/var/lib/cloud/seed/config_drive” which is the read-only ISO9660 CD-ROM image...

Thanks! Uploading the new system_info.pl file fixed the divide by zero error. My search for “system_info.pl” did not find that closed issue for some reason. Regarding ZFS used/available disk space, Webmin still reports “Error! Warning! The 416 kB filesystem mounted at /var/lib/cloud/seed/config_drive has no free disk space!” Webmin knows that this is a ISO9660 CD-ROM (actually virtual) read-only disk, as shown by edit_mount.cgi. Warning that a read-only disk image has no free space for writing data...

We recently updated to Webmin 1.9.10 on a VPS hosted by DigitalOcean running FreeBSD 11.2-Release-p9 (Generic) with ZFS and encountered an error that is likely related to this problem. When the Dashboard tried to load, the following error was reported: “mount::list_system_info failed : Illegal division by zero at /usr/local/lib/webmin-1.910/mount/system_info.pl line 31.” Commenting out line 31, which is “my $free_percent = 100 - int(($total - $free) / $total * 100);” avoids the error.
