You can create a single pool and grow it as needed. From that pool, you create filesystems. If you want to create multiple pools (due to redundancy/performance requirements being different), ZFS will keep them separated. And again, you will create filesystems/datasets from each one independently. http://download.oracle.com/docs/cd/E19963-01/html/821-1448/index.html http://download.oracle.com/docs/cd/E18752_01/html/819-5461/index.html -- Giovanni Tirloni _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
