ZFS versions [was: need help]

[grarpamp]

FYI
There are both zpool and zfs versions.
They are independant. Though to fully enable some
features both need upgraded. See zpool(1M), zfs(1M)
and the ticket/psarc cases listed in the urls for more.

The canonical references and utilities [read-only] are:

http://opensolaris.org/os/community/zfs/version/n/
 zpool upgrade -v
 zpool upgrade
http://opensolaris.org/os/community/zfs/version/zpl/n/
 zfs upgrade -v
 zfs upgrade

The parameter setting method is not preferred.

FreeBSD RELENG_7 and above are at:
zpool 13
zfs 3

OpenSolaris is at:
zpool 18
zfs 4
