I am planning to upgrade my current TrueNAS system from the Gigabyte X58 board with Xeon X5660 and 48GB of Crucial DDR3 to the Asus X99 Deluxe with Xeon E5 1660v3 and 256GB of ECC registered DDR4. As far as the OS is concerned, do I need to do anything special before the upgrade, or should it just work fine once I attach the drives to the new board?

You should be able to port everything over and run a system update to make sure the the firmware is up to date.

If the system is already setup with GPT for the boot selection it's one less thing to deal with. If it's not it's an easy fix with a livecd and moving the partition over by 50mb and creating an EFI partition and running efi-grub.

The system drive is a legacy boot I think, but I have no idea what the partition table is. It started as an older install of FreeNAS, and got updated. I enabled CSM on my X99 and the BIOS is up to date, so I don't think that should be an issue.

Yeah, it should just work but, if you run into a no-boot situation that's where I would be looking.

I ran into it with moving from 8700K to 12700K on the intel side even though the board supported CSM it didn't want to play well until I converted the drive over to GPT and added EFI. I don't think you'll see this though with moving up with Xeon but, it's a consideration if it's vital to have little downtime.

So it seems to be just be working. Well, first I had to change the boot order to the boot drive, it was trying to boot from a data drive lol.

Does ZFS aggressively cache the data using all available RAM?
