How to remove dataset from Solaris zone and mount it as lofs

Because of building mail system I need to export ZFS filesystem via NFS to other node, where postfix with deliver will save messages to mail boxes. As you can see in this installation transcript I configured whole zpool „studmail” as ZFS dataset for zone st1. Unfortunatelly, you can not simply share ZFS via NFS in non-global zone:

root@st1:~# zfs list
NAME                         USED  AVAIL  REFER  MOUNTPOINT
studmail                     301M  1.78T  28.0K  none
studmail/etc                4.52M  1.78T  4.19M  /data/etc
studmail/studmail            480K  1.78T   417K  /data/studmail
studmail/var                 296M  1.78T   294M  /data/var

root@st1:~# zfs set sharenfs=rw=@192.168.X.X/32,anon=0 studmail/studmail
cannot set property for 'studmail/studmail': 'sharenfs' cannot be set in a non-global zone

04.02 Configuration of container st1

After installation and initial configuration of st1 container you need to look on working services and disable those, which are not necessary. But at first I will set up more comfortable environment to work. I will change default shell to zsh and home directory of root user. I will use GNU sed for this purpose. Remember that /usr/local directory is inherited from global zone in read-only mode.

04.01 Installation of container st1

Creation of container named st1, without resource control, with inherited standard directories and additionally inherited /usr/local dir (read only mode). Configured two network Quad Fast Ethernet cards: qfe4 and qfe5 in shared mode. Added ZFS pool (zpool) named studmail.

04. Containers (Solaris zones)

Solaris 10 has embedded some kind of virtualization mechanism, which is known as Solaris Zones. This is not only jail, but also resource controller for zones. I will not write about mechanism, because you can find this in documentation on Sun/Oracle sites and other blogs. I will give you some simple examples how to configure and install zone on Solaris 10.
