I'm not positive if you're referring to me, but you might be. The original context of that was with respect to LU. Segregating the root file systems from user data makes a lot of sense with LU and UFS file systems, because you don't want to waste time, space, and effort copying around non-OS data when you do an upgrade. That does *NOT* translate into separating the ZFS pools once you have a ZFS root. Instead, it translates into separate ZFS file systems for each root and for user data. Note: file systems, not pools. In other words, as I said before, the issues are different, and the whole slicing nonsense goes away. -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
