Problems aligning pool as 4k

[eroji]

I am recreating my pool in order to align them in 4k, but every time I try to create it using the wizard, the ashift value shows 9 instead of 12. Manually creating the partition on disk and zpool is able to produce ashift 12, but I am unable to import the volume in FreeNAS GUI.

My spec is:
X10SRL-F
E5-1650V3
64GB DDR4 ECC
12x Toshiba 5TB MD04ACA500
Intel 750 400GB NVMe
SanDisk 64GB USB

Build version (from System -> Information)?

Using the latest FreeNAS-9.10-RELEASE (2def9c8). I did some testing and it seems like the pool is functioning at full speed. The 9 ashift value was indicating the boot volume.
