Hi Tim, You were right. I wasn't using the dev repository, so i was stuck into an old build of zfs.
So i did those step: - pkg set-publisher -P -O http://pkg.opensolaris.org/dev/ opensolaris.org - pkg image-update -v : download and upgrade. - reboot Then i have version 4 now of zfs and version 19 of zpool. And the release is now: $ cat /etc/release OpenSolaris Development snv_127 X86 Copyright 2009 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 06 November 2009 Thanks a lot. So i learn that the release at http://hub.opensolaris.org/bin/view/Project+jeos/200906+Prototype#HDownloads is pretty old and need to be updated :) -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
