Is there anyway to do this without losing the data in the file system?
I don't think your data is actually gone. When zfs filesystems get handed out to non-global zones, a special "bit" is set on the filesystem, in the form of a zfs property called "zoned". Here is what the man page says: After a dataset is delegated to a non-global zone, the "zoned" property is automatically set. A zoned file system cannot be mounted in the global zone, since the zone administrator might have to set the mount point to an unac- ceptable value. The global administrator can forcibly clear the "zoned" pro- perty, though this should be done with extreme care. The global administrator should verify that all the mount points are acceptable before clearing the property.
