ZFS filesystems taking time to mount in NG Zone - Solaris 11

Hi,

We have a number of Solaris 11 LDoms hosting plain old Solaris 11 zones, one zone per LDom. There's nothing particularly stunning about them.

zonename: Abcdefg

zonepath: /zones/Abcdefg

brand: solaris

net:

       physical: vlanXXX

net:

       physical: vlanXXX

net:

       physical: vlanXXX

dataset:

       name: ABCD_POOL/export

       alias: export

dataset:

       name: ABCD_POOL/data

       alias: data

My issue is that the datasets seem to take several minutes to mount after the NG zone has booted. zlogin from the global zone works, I can login, but those datasets take time to wake up and mount on the NG zone.

The zfs filesystems don't show up in a df -h, and just show an empty mountpoint to ls
