We've updated the wiki to help clarify this confusion. The consensus best practice is to have enough RAM that you don't need to swap. If you need to swap, your life will be sad no matter what your disk config is. For those systems with limited numbers of disks, you really don't have much choice about where swap is located, so keep track of your swap *usage* and adjust the system accordingly. -- richard This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
