You are mirroring devices and them striping the mirrors together. AFAIK, RAID0+1 is not supported since a vdev can only be of type disk, mirror or raidz. And all vdevs are stripped together. Someone more experienced in ZFS can probably confirm/deny this. -- Giovanni Tirloni sysdroid.com -------------- next part -------------- An HTML attachment was scrubbed...
