You could change the raid type of the aggregate from raid_dp to raid_4 and get back 1 disk (it will be spared), pay attention to te raid_size limitation of the raid4.

unfortunately you cant remove a disk from an aggregate once is created, you'll have to destroy it and create it from scratch.

2 disks are zeroing i have to wait ...

1 is pending

i will create 1 aggr of 12 disk on first head

1 aggr of 8 disk on 2 nd head

i was looking to create 10 disk for each one with 2 spares...

Are you creating two empty aggregates in this moment or have you already got a 12disk aggregate with some data in head1?

if all the 20 disks are spared right now you could reassign 1-2 disk from head1 to head2, that can be done only with unused\spare disk (not partecipating in any aggregate)

I had 1 aggr having 8 disks already used 6 data + 2 spares

inspite of adding 2 disks i added 3

result i will have 11 data + 2 spares

remaining will be 11 disks

==> so i will add one other disk to the expanded aggr to have 12 disks + 2 spares

and on the other head 6 data + 2 spares

is it also possible to create a big aggr with 2 raid group of 11 disks 22 data + 2 spares

but i think it is not a god idea for 2 TB disks

yes it is possible but keep in mind that the head 2 of the filer must own at least 3 disks for hosting the root volume (1data+1parity+1spare in raid4).

however, you can freely move spare disk from one head to the other.
