Debian Linux (Jessie)
1x SSD attached storage to a KVM virtual machine (VirtIO)
Default Linux template incorrectly calculates the used space on partition "/". Calculation appears to return / be based off the size of the underlying hard disk. When there are multiple partitions involved this can be quite incorrect.
So, it outputs the total used space on partition + size of other partitions

In Zabbix
Free disk space on / = 37.07 GB Free disk space on / (percentage) = 10.59 % Free inodes on / (percentage) = 99.96 % Total disk space on / = 350 GB Used disk space on / = 312.93 GB
I am unsure if this is a bug introduced in Zabbix 3.0 as we are testing the alpha version on a separate machine with a different hardware configuration.
