I suggest to read up on ZFS a bit more. With OpenSolaris 09.06, with three 20 GB virtual disks, I'm getting = this: root@opensolaris:~# zpool create tank raidz c8t1d0 c8t2d0 c8t3d0 root@opensolaris:~# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT tank 59.5G 881K 59.5G 0% ONLINE - root@opensolaris:~# zfs list NAME USED AVAIL REFER MOUNTPOINT tank 91.2K 39.0G 25.3K /tank Which is exactly the same behavior as with FreeBSD. And of course you = only get to store 40 GB worth of files on this filesystem. Stefan --=20 Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
