So: RAIDZ would be 8 x 1.5tb = 12tb - 1.5tb = 10.5tb RAIDZ2 would be 8 x 1.5tb = 12tb - 3.0tb = 9.0tb RAIDZ3 would be 8 x 1.5tb = 12tb - 4.5tb = 7.5tb But not really that usable space for each since the mirroring? So do you not mirror drives with RAIDZ2 or RAIDZ3 because you would have nothing for space left.... -Jason _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
