Description
Running llmount.sh with FSTYPE=zfs fails with "mount.lustre: lustre-mdt1/mdt1 has not been formatted with mkfs.lustre or the backend filesystem type is not supported by this tool".
This was seen while working on LU-3606 (ZFS). The goal is to create a very small working ZFS instance for dev purpose. This is combined MDT/MGS. Changing test-framework.sh to using mount.lustre binary worked for me. This may just not be a bug. I am raising it to understand if this is really a bug or something to do with my environment. What are the difference of passing -t lustre vs using mount.lustre. I thought they ultimately boils down to same.
This fails

This was fix by changing test-framework.sh

Essentially changing from using mount -t lustre to using mount.lustre binary makes it work.
