Hi, I''m currently doing some tests on a SF15K domain with Solaris 10 installed. The target is to convince my cu to use Solaris 10 for this domain AND establish a list of recommendations. The ZFS perimeter is really an issue for me. For now, I''m waiting for fresh informations from the backup software vendor about ZFS support. No ZFS-acl support could be annoying. Regarding "system partitions" (/var, /opt, all mirrored + alternate disk), what would be YOUR recommendations ? ZFS or not ? TIA Nicolas This message posted from opensolaris.org

ZFS or not ?/var for now must be UFS since Solaris 10 doesn''t not have ZFS root support and that means /, /etc/, /var/, /usr. I''ve run systems with /opt as a ZFS filesystem and it works just fine. However note that the Solaris installed puts stuff in /opt (for backwards compat reasons, ideally it wouldn''t) and that may cause issues with live upgrade or require you to move that stuff onto your ZFS /opt datasets. -- Darren J Moffat

That might be painful to upgrade, though.> I''ve run systems with > /opt as a ZFS filesystem and it works just fine.

I have to unmount it before using Live Upgrade, though, because it refuses to leave /opt on a separate filesystem. I suppose it''s right, since the package database may refer to files in /opt, but I haven''t had any problems. David
