I upgrade to stable r192523: FreeBSD morzine.restart.bel 7.2-STABLE FreeBSD 7.2-STABLE #0: Thu May 21 13:18:53 CEST 2009 root@morzine.restart.bel:/usr/obj/usr/src/sys/MORZINE i386 some strange things: just after boot: [root@morzine ~]# zfs upgrade This system is currently running ZFS filesystem version 3. The following filesystems are out of date, and can be upgraded. After being upgraded, these filesystems (and any 'zfs send' streams generated from subsequent snapshots) will no longer be accessible by older software versions. VER FILESYSTEM --- ------------ 1 pool1 1 pool1/qemu 1 pool1/squid 1 pool2 1 pool2/WorkBench 1 pool2/backup 1 pool2/download 1 pool2/qemu 1 pool2/sys 1 rpool 1 rpool/home 1 rpool/root 1 rpool/tmp 1 rpool/usr 1 rpool/var 1 rpool/var/spool [root@morzine ~]# zfs upgrade -v The following filesystem versions are supported: VER DESCRIPTION --- -------------------------------------------------------- 1 Initial ZFS filesystem version 2 Enhanced directory entries 3 Case insensitive and File system unique identifer (FUID) For more information on a particular version, including supported releases, see: http://www.opensolaris.org/os/community/zfs/version/zpl/N Where 'N' is the version number. And now, after a few minutes: [root@morzine ~]# zpool upgrade This system is currently running ZFS pool version 13. The following pools are out of date, and can be upgraded. After being upgraded, these pools will no longer be accessible by older software versions. VER POOL --- ------------ 6 pool1 6 pool2 6 rpool Use 'zpool upgrade -v' for a list of available versions and their associated features. [root@morzine ~]# zpool upgrade -v This system is currently running ZFS pool version 13. The following versions are supported: VER DESCRIPTION --- -------------------------------------------------------- 1 Initial ZFS version 2 Ditto blocks (replicated metadata) 3 Hot spares and double parity RAID-Z 4 zpool history 5 Compression using the gzip algorithm 6 bootfs pool property 7 Separate intent log devices 8 Delegated administration 9 refquota and refreservation properties 10 Cache devices 11 Improved scrub performance 12 Snapshot properties 13 snapused property For more information on a particular version, including supported releases, see: http://www.opensolaris.org/os/community/zfs/version/N Where 'N' is the version number. Strange isn't it o-) By the way all seems ok!
