You can add arbitrary-sized vdevs to a pool, but you can't add any drives to an existing raidz[123] vdev. You can even add things like a mirrored vdev to a pool consisting of several raidz[123] vdevs. :-) Thus, it would certainly be possible to add, say, a 4-drive raidz1 to your 2x7 pool. It wouldn't perform quite the same as a 3x7 pool, but it still would perform better than the 2x7 pool. -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA Timezone: US/Pacific (GMT-0800) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
