This would be better.
Will the ZFS plugin be supported a long time in OMV? Don't want to set up ZFS and then in a few updates I can't use it anymore.
I don't actually use the Plugin to create and administer my pools, I use the command line. I use the plugin because it integrates well with the other settings. I can't see support going anytime soon. A lot of work has been put into it of late. It's unlikely to just get abandoned.
