The Open Solaris ZFS driver [1] is currently missing a lot of the minimum features [2] that the Cinder team requires with all drivers. As a result, it's really broken. I wanted to gauge who is using it, and if anyone was interested in fixing the driver. If there is not any activity with this driver, I would like to propose it to be deprecated for removal.
