Otherwise, I'd love to use all 8. The system itself won't take too much space. You can create one large slice form the rest of the disks and the same slices on the rest of the disks. Then you can create one large pool from 8 such slices. Remaining space on the rest of the disks could be use for swap for example, or other smaller pool. Now I would consider creating raid-10, and not raid-z, something like: zpool create local mirror s1 s2 mirror s3 s4 mirror s5 s6 mirror s7 s8 Than I would probably create local/zones/db and put zone here, then create additional needed filesystem in that one pool. btw. in such a config write cache would be off by default - I'm not sure it will be a problem or not. -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
