Quite; Mac OS X has already introduced a little confusion with the difference in its zpool versions: galoot% uname -a SunOS galoot 5.11 snv_85 i86pc i386 i86pc galoot% /usr/sbin/zpool upgrade -v |grep 6 6 bootfs pool property=20 crackityjones:~ ceri$ uname -a Darwin crackityjones.private.submonkey.net 9.2.2 Darwin Kernel Version 9.= 2.2: Tue Mar 4 21:17:34 PST 2008; root:xnu-1228.4.31~1/RELEASE_I386 i386 crackityjones:~ ceri$ zpool upgrade -v |grep 6 This system is currently running ZFS version 6. 6 bootfs pool property and OSX directory type I've yet to check what happens with a zpool created on the Mac being imported on the OpenSolaris machine or vice versa.
