Advanced ZFS install possible ? rpool = 2 x raidz

[Denny Fuchs]

hi,

is it possible to create a pool out of 2 x Raidz-1. I assume, that the performance is quite better, than now for a raidz-2 out of 8 disks. Or can I install on a Raidz-1 and add a second Raidz-1 to the pool?

Yes you can add first you installation a RaidZ. In the new running system add the other disk to another RaidZ. So after you have an RaidZ10. For example:

zpool add  -o ashift=12 rpool raidz1  diskid1 diskid2 ...
