ZFS: /system/zones "respawning" on rpool

Hi,

I have this fresh installation of Solaris 11.3 sparc.
I have two zfs pools both using two disks in mirroring mode, both are online.

I want to move /system/zones, currently rpool/VARSHARE/zones, from rpool to the other zfs pool so my zones don't consume space on the disks allocated to rpool. Since it's a fresh install, /system/zones is currently empty, no zones have been created yet.

I boot the system in signle user mode
Then destroy rpool/VARSHARE/zones:
Code:
zfs destroy rpool/VARSHARE/zones

create the new volume and set mount point:
Code:
zfs create -o mountpoint=/system/zones storage/zones

After rebooting the system, rpool/VARSHARE/zones is automatically recreated and I have this error message:
Code:
cannot mount 'zpool/zones' on '/system/zones': mountpoint or dataset is busy
... transitioned to maintenance

If instead of destroying rpool/VARSHARE/zones I change it's mountpoint to none, everything seems to work as wanted.

So here's the question, what am I doing wrong? why is rpool/VARSHARE/zones respawning when destroyed?

Thanks and sory for the long post.

zoneadmd(1M)						  System Administration Commands					      zoneadmd(1M)

NAME
zoneadmd - zone administration daemon SYNOPSIS
/usr/lib/zones/zoneadmd DESCRIPTION
zoneadmd is a system daemon that is started when the system needs to manage a particular zone. Because each instance of the zoneadmd daemon manages a particular zone, it is not unexpected to see multiple zoneadmd daemons running. This daemon is started automatically by the zone management software and should not be invoked directly. The daemon shuts down automati- cally when no longer in use. It does not constitute a programming interface, but is classified as a private interface. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWzoneu | +-----------------------------+-----------------------------+ |Interface Stability |Private | +-----------------------------+-----------------------------+ SEE ALSO
svcs(1), zlogin(1), svcadm(1M), zoneadm(1M), attributes(5), smf(5), zones(5) NOTES
The zones(5) service is managed by the service management facility, smf(5), under the service identifier: svc:/system/zones:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. SunOS 5.11 1 Nov 2004 zoneadmd(1M)
