Folks,

Just a quick question. Many google searches have been fruitless..

Trying to import a zfs pool ( ZFS Version 4 ) to a server running ZFS
version 3.

Obviously this fails and sets

state: FAULTED

status: The pool is formatted using an incompatible version.
action: The pool cannot be imported.  Access the pool on a system
running newer
        software, or recreate the pool from backup.

My question is, is there a way to upgrade my zfs version 3 to zfs
version 4 without upgrading the entire OS ?

TIA

I don't know if I'm missing something obvious here - but did you try
"zpool upgrade"?

We cannot import the zpool to do the upgrade..

zpool currently sits on a server with ZFS v4. When we try a zfs import
to a server running ZFS v3 we get the error:

# zpool import
  pool: zfspool
    id: 364449855*********
 state: FAULTED
status: The pool is formatted using an incompatible version.
action: The pool cannot be imported.  Access the pool on a system
running newer
        software, or recreate the pool from backup.

config:

There will be patches to take it to zfs v4

you will have to ask zfs guys on opensolaris for which ones - as you
will not find them through sunsolve

I don't see any ambiguity in that message.  You can't expect an older
version of ZFS to import a pool built with a newer version.

Have you applied all of the applicable ZFS patches?

Thanks for your reply..

I do understand that I cannot expect the older version to import a
newer zfs pool.. That is why I asked the question; is there a way to
upgrade the older zfs version without having to upgrade the OS..

I will take kangcool's advise and ask the opensolaris guys if there is
a particular patch that needs to be applied.

chances are if you apply the current recommended bundle you will get
the most recent ZFS version that ships with 10.

Thanks Tim.

I will apply the latest patch cluster for Solaris 10 and see how we go
from there.

I had no luck on the opensolaris forums.

zpool import -f datapool produces same error as above.

I didn't see you ask - zfs-discuss@opensolaris.org would have been the
place to try.

I didn't try there tbh, soon as we can schedule downtime on the box I
will add the newest Sol 10 Patch cluster !

FWIW, the latest S10 release is version 4.

ZFS version 4, not Solaris version.

yes ZFS version 4 was what I meant, sorry for that.

Is it likely that S10 will always have ZFS version 4 for compatibility 
and only receive patches applicable to version 4?

No, ZFS boot is slated for update 6, which will require a more recent
version.

Franco,

I had to installed the Recommended Patch cluster to upgrade my ZFS.
There's so many different patches to get the full set of Kernel
patches to take affect that it is truly easier just to do the full
cluster install (patches).

I also was able to "upgrade" the ZFS pools while in production.  I did
nine pools on 3 different servers without interrupting the customer or
any web apps, or databases.(mysql).

Good luck.
