zfs discuss - Nov 2008 - is putting zone paths on zfs supported in Solaris 10 u5/u6 ?? Documentation on that? - 66124245

ZFS experts!

cu is looking for _documentation_  about putting zone paths on zfs.  cu 
is running 5.10 KP 137111-06.  he needs to make sure u5 kp is ok with 
zone roots.  Also has FSs mounted via legacy.

So...anybody have documentation on which u5 or u6 of Solaris (NOT 
OpenSolaris) supports zfs, if any update, for zone paths?

Brian,
Are there any known problems with a whole root zone that has a separate
zone opt and var from the zone root? See zone configuration below or do
we just need to ensure that the ZFS file systems are mounted?


Thank you,
Rich

Richard,

I''m trying to find documentation that I can actually send you.

I must amend what I said earlier: my colleague told me that zone path on

ZFS at S10 u5 _is_ supported, but you can''t upgrade the OS, so
it''s "not

recommended".  Where''s the documentation on that? -- I
don''t know.  I''m
trying to find documentation on it from the experts.

As for S10 u6, you can see under "What''s New":

    http://www.sun.com/software/solaris/whats_new.jsp

...under "Data Management" it says "ZFS as a root file
system".  So S10
u6 definitely has that for a feature.

I''m emailing the experts right now.  When I can find some documentation
to point you to, I''ll let you know.

If you need assistance in the meantime, please *call* me or the next 
available OS engineer.

It certainly is on update 6.
