What I had in mind was the latest MFC regarding ZFS (pool) version 13 on May 20th (two weeks after the 7.2 release): http://svn.freebsd.org/viewvc/base?view=revision&revision=192498 And the corresponding entry in /usr/src/UPDATING: "20090520: Update ZFS to version 13. ZFS users will need to re-build and install both kernel and world simultaneously in order for the ZFS tools to work. Existing pools will continue to work without upgrade. If a pool is upgraded it will no longer be usable by older kernel revs. ZFS send / recv between pool version 6 and pool version 13 is not supported." Regargs, Panagiotis -- Panagiotis J.
