[OpenIndiana-discuss] zpool upgrade in OI151a5?

[Dan Swartzendruber]

So I did the pkg image-update to go to 151a5.  I grabbed off a copy of the
root pool first. Boot and activated and all seemed well.  I happened to do
'zpool status' and saw these:

 

root at openindiana:~# zpool status

  pool: rpool1

 state: ONLINE

status: The pool is formatted using an older on-disk format.  The pool can

        still be used, but some features are unavailable.

action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the

        pool will no longer be accessible on older software versions.

I updated rpool first, and was dismayed to see the following:

 

Successfully upgraded 'rpool1' from version 28 to version 5000

 

Say what?  I then did 'zpool get version rpool1' and get:

 

root at openindiana:~# zpool get version

NAME    PROPERTY  VALUE    SOURCE

rpool1  version   -        default

tank    version   28       local

 

So tank still explicitly lists the pool version as 28, but the root pool is
showing '-'?  Should I fall back to my backup pool image?  Any ideas what
the **** happened?
