Because what you've created is a pool containing two components: - a 3-drive raidz - a 3-drive mirror concatenated together. I think that what you're trying to do based on your description is to create one raidz and mirror that to another raidz. (Or create a raidz out of mirrored drives.) You can't do that. You can't layer raidz and mirroring. You'll either have to use raidz for the lot, or just use mirroring: zpool create temparray mirror c1t2d0 c1t4d0 mirror c1t5d0 c1t3d0 mirror c1t6d0 c1t8d0 -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
