For some reason, after upgrading to 9.1.1 and performing a zpool upgrade from version 28, I now get a dash character "-" for the current version of the zpool. Here is what was done:

1. Performed a flawless 8.3.x to 9.1.1 GUI upgrade to FreeNAS; no problems were encountered.

2. On FreeNAS 9.1.1 Guide, page 47, Para 2.6.6 Upgrading a ZFS Pool, I performed the steps exactly as written:
zpool status (All values were zeros)
zpool get version VOLUME1 (It responded with version 28 which is expected.)
zpool status -x (all pools are healthy)
zpool upgrade volume1 (I got a sucessful upgrade exactly like page 48 says.

However, if I subsequently run "zpool get version VOLUME1" it will not give me a version, and just has a dash "-" charater. So, what is the version number now? Is this a problem?

ASUS Mobo, i7, built-in SATA controllers, 3Tib X6 drives.

It's OK. The pool is now using feature flags (pool version "5000"). The zpool version property has no value in this case. You can run zpool get all to see all enabled/supported features (feature@ at the end of the list).
