Hi,
starting with 9.3.0.2.x builds zpool status gives me a "block size: 512B configured, 4096B native" (using WD Red drives).

I tried to reformat a recreate the pool, but the warning remains.

Is there a way to solve the problem?
Keeping the drives like this impact on performance/stability/reliability of the pool?

Regards Jack

When you create your vdev, (Disks|ZFS|Pools|Virtual device |add) you have to check the Advanced Format option there

Did you check the advanced format switch at Disks|Format ?

Can you post the output of the command

ashift: 9

there is a way to realign an already created vdev? (deleting it an recreating is not an option)

no there is not. you have to recreate the pool

ok thanks.

If you are already using it then it's not that big a deal for home NAS's. Yes it does hurt performance a bit, but you probably wouldn't notice it unless you are running some virtuals off it or have 10Gb NIC.
