So I am planning on swapping out my motherboard in my main UnRaid server this weekend. I currently have an older Asus socket 775 board with a core 2 duo, it has a video card, an I/O card and my 16 port Areca SATA raid controller. The new board has onboard video so I won't be putting the video card back, I have drives connected to the four port I/O card as well as onboard SATA ports. As long as I put the same drives that are currently connected to the onboard SATA ports, onto the onboard SATA ports of the new board, and of course the Areca and four port I/O, card I should be ok in terms of drive assignments? Anything else I need to worry about? The new board is an Asus P8Z68-V PRO.

 

Thanks

The connections should not matter. Once you set the new motherboard to boot the USB stick it should recognize the drives and start the array as if nothing changed.

Just be careful to note the Parity drive by serial number before starting.  You shouldn't need that information, it should be plug and play.  But just in case anything goes wrong you want to be able to identify the parity drive.

Just to be sure I'd leave the parity drive out when you start it. It will show it's missing but all the data drive should be correct, then shut down and add it, and restart. I just swapped my whole system twice in the last few days and it worked for me.

unRAID won't just swap the drive assignments, but if you're worried it will then just keeping the parity drive out of the system would be useless.
