I'm trying to mount zfs snapshot. It should to be so easy...but I can't do that.
I'm using Ubuntu Server 11.10 Oneric, kernel 3.0.0-15-server.

Installed ZFS from ppa also I'm using zfs-auto-snapshot.
With manually created snapshots the same situations.

How to mount zfs snapshot?

root@us1:/# zfs list -t snapshot

NAME                                                            USED  AVAIL  REFER  MOUNTPOINT

tank/www@zfs-auto-snap_hourly-2012-02-11-1917                   0      -   268K  -



root@us1:/# zfs mount tank/www@zfs-auto-snap_hourly-2012-02-11-1917 /mnt/snapshot/tank/www

too many arguments

usage:

        mount

        mount [-vO] [-o opts] <-a | filesystem>



For the property list, run: zfs set|get



For the delegated permission list, run: zfs allow|unallow



root@us1:/# zfs mount tank/www@zfs-auto-snap_hourly-2012-02-11-1917

cannot open 'tank/www@zfs-auto-snap_hourly-2012-02-11-1917': operation not applicable to datasets of this type
