Not that I can see. Not every solaris update includes a change to the
zpool version number. Zpool version 4 is the most recent version on
Solaris 10 releases.

Hi,
I reinstalled our Solaris 10 box using the latest update available.
However I could not upgrade the zpool

bash-3.00# zpool upgrade -v
This system is currently running ZFS version 4.

The following versions are supported:

VER  DESCRIPTION
---  
 1   Initial ZFS version
 2   Ditto blocks (replicated metadata)
 3   Hot spares and double parity RAID-Z
 4   zpool history

For more information on a particular version, including supported releases,
see:

http://www.opensolaris.org/os/community/zfs/version/N

Where 'N' is the version number.

bash-3.00# zpool upgrade -a
This system is currently running ZFS version 4.

All pools are formatted using this version.


The sun docs said to use zpool upgrade -a. Looks like I have missed
something.

Hi Dick (from the solaris on x86 list),

- First off, and you may already know this, you can upgrade - but it's
a one-way ticket.  You can't change your mind and go "backwards", as
in, down-grade to a previous release.  And, what if you want to
restore a snapshot to a box running an older release of ZFS...

- Secondly, you're not *required* to upgrade.  If there is even a 1 in
a 1,000,000 chance that you might want to use the pool with a previous
release of *olaris - *don't* do it!  And this includes moving the pool
over to a different *olaris release - which is a requirement that
cannot always be foreseen.

- 3rd, in many cases, there is no "loss of features" by not upgrading.
 Again - I say - in most cases - not in all cases.

To examine the current version or to upgrade it, please read (latest
version of) the ZFS admin guide doc #  817-2271.  Look at "zpool get
version poolName" and "zpool upgrade"

Recommendation (based on personal experience) leave the ondisk format
at the "SXDE" default version for now.
