I’m preparing a TrueNAS Core system for a migration to TrueNAS Scale. As part of that, I need to re-create one of my pool that is currently GELI-encrypted. I have copied all the datasets to other pools temporarily and will be destroying the pool soon to re-create it.
I know I need to make sure to set ashift correctly when doing this, but are there any other options that you can only set at pool creation time that I should set when I do this? I don’t want to have to re-create the pool again later because I forgot to set something.
