Zone cloning with zfs
Sun documentation about zone cloning describe if zone cloning, which zonepath is on a ZFS pool, zone will be cloning by zfs snapshot. On my system zones cloned by files copying. How I can troubleshoot that?

Code:

zdb

zdb(8)							  System Administration Commands						    zdb(8)

NAME

       zdb - ZFS debugger

SYNOPSIS

       zdb pool

DESCRIPTION

       The  zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on
       disk and is self-repairing, zdb should only be run under the direction by a support engineer.

       If no arguments are specified, zdb, performs basic consistency checks on  the  pool  and  associated  datasets,	and  report  any  problems
       detected.

       Any options supported by this command are internal to Sun and subject to change at any time.

EXIT STATUS

       The following exit values are returned:

       0    The pool is consistent.

       1    An error was detected.

       2    Invalid command line options were specified.
