zfs discuss - Jan 2010 - ZFS upgrade.

Hello,

Is there a way to upgrade my current ZFS version.  I show the version could
be as high as 22.

I tried the command below.  It seems that you can only upgrade by upgrade
the OS release.

[ilmcoso0vs056:root] / # zpool upgrade -V 16 tank
invalid version ''16''
usage:
        upgrade
        upgrade -v
        upgrade [-V version] <-a | pool ...>

[ilmcoso0vs056:root] / # zpool upgrade -a
This system is currently running ZFS pool version 15.

All pools are formatted using this version.
[ilmcoso0vs056:root] / #

[ilmcoso0vs056:root] / # zpool upgrade
This system is currently running ZFS pool version 15.

[ilmcoso0vs056:root] / # zpool upgrade -v
This system is currently running ZFS pool version 15.

The following versions are supported:

The version of Solaris you are running only suport ZFS versions up to version 15
as demonstrated by your zfs upgrade -v output. You probably need a newer version
of Solaris, but I cannot tell you if any newer versions support later zfs
versions.

This forum is for OpenSolaris support.  You should contact your Solaris support
provider for further help on this matter.

cheers,
James

John,

You are already running the Update 8 kernel (141444-09). That is the 
latest version of ZFS that is available for Solaris 10.
