Hello,
it's not clear to me the correct way to detach an external ZFS drive, let's suppose it is alone in a zpool.
Should I "zfs unmount" and then turn it off, or should I just give the "eject" command with the Finder? I think the results are not the same: with "zfs unmount" I can give after that the "zfs mount" command, and if I use the eject from the Finder, I have to give the "zpool import" command.
I'm new to ZFS and I would like to be sure not to turn off a filesystem still in use.
