Hi!

This might be slightly off-topic, but since the ZoL hosts a fork of filebench and filebench has a long history with ZFS i give it a shot. Is anyone running filebench agains ZFS on a recent Linux distribution? I am having trouble running it on Ubuntu 16.04:

filebench> set $dir=/tank/bench01
filebench> run 60
