Why is it not possible to create a pool with single disks with no redundany while this can be created via CLI?
(sudo zpool create -o ashift=12 zpool /dev/sda /dev/sdb)
But also a single drive would have no data redundancy! So this is probably NOT the reason . I think they simply forgot to add this to the code.
And as a lazy person i would like to do it in GUI of course.
