Is it possible or advisable to create zfs pool on top of a gstripe? Say I have 3 disks of equal size and that speed is more important than redundancy, so instead of creating raidz1 having 2/3 space (or whatever), can I create gstripe with 3 disk worth of space, and then create a zpool on top of it? To combine the advantages of gstripe (3 disks worth of space) and zfs (compression, snapshots, etc)?
