zfs discuss - Apr 2008 - ZFS volumes in non-global zones

Hi all,

just a quick question about ZFS volumes inside non-global zones. The zfs manpage
seems a bit paradox about it - can it be used or not?

The manpage zfs(1M) says for volumes:
       volume         A logical volume exported as a block  device.
                      This  type  of  dataset  should  only be used
                      under special circumstances; file systems are
                      typically  used.  Volumes cannot be used in a
                      non-global zone.

Later in the section "Zones" it reads:
       A ZFS emulated volume can be added as a  device  to  a  non-
       global zone by using zonecfg''s "add device"
subcommand. How-
       ever, its physical properties can only be  modified  by  the
       global administrator.

The Zones section part basically says what I would be expecting. Also adding 
zvols to zones using zonecfg''s ''add device'' does
work. But the sentence "Volumes
cannot be used in a non-global zone." is a bit disturbing...

Any insights?

Thanks and have a nice weekend all,
	Ralph

                 However, this is not necessarily a good idea. It is hard
                 to be sure where they are going to land, and it could be
                 dangerous sitting under them as they fly overhead.
