When trying to set the mount point for the / = file system, I am getting strange errors: root@vm:~ # zfs set mountpoint=3Dnone newpool/ROOT cannot open 'newpool/ROOT': dataset does not exist root@vm:~ # zpool import -c /tmp/newpool.cache -R /mnt newpool root@vm:~ # zfs set mountpoint=3Dnone newpool/ROOT cannot unmount '/mnt': Device busy root@vm:~ # zfs set mountpoint=3D/ newpool/ROOT/default cannot unmount '/mnt': Device busy root@vm:~ # zfs set mountpoint=3D/tmp newpool/tmp root@vm:~ # zfs set mountpoint=3D/usr newpool/usr root@vm:~ # zfs set mountpoint=3D/var newpool/var root@vm:~ # zfs set mountpoint=3Dnone newpool/ROOT cannot unmount '/mnt': Device busy root@vm:~ # zpool export newpool root@vm:~ # zfs set mountpoint=3Dnone newpool/ROOT cannot open 'newpool/ROOT': dataset does not exist So basically, when the pool is not mounted the system says =84dataset = does not exist=93 but when I mount it and try to change the mount point = it comes back with =84Device busy=93. Any ideas on how I am supposed to = set the mount point for the root file system (first & last line of the = commands listed above)? Many thanks.
