Setting up first time NAS, after TOS installed am trying to go through initilization but at the file system selection screen I am only presented with one option: Ext4

I'm using two 6TB ironwolf drives, unsure if i'm missing something but the setup info i've found all says the Btrfs option should be there...

Any ideas how to move forward?

Could I setup as Ext4 and then reformat to Btrfs?

Thanks for any help!

The default file system is EXT4.
You should proceed with EXT4 first, and delete the created volume and storage pool to Create a new one and choose the file system as Btrfs.

Thank you for helping! I was able to delete the volume and storage pool... but when I create new, it shows only Ext4 option

I am sorry that I just confirmed with the tech team here, for ARM models, only EXT4 file system is supported at the moment.
