Hi @JonathanM,
 
Thanks for the reply. The disks are still readable but I'm just a little cautious as Disk 3 has an error:

 
edit: i made use of the parity swap feature! at first it wouldn't let me do it with a "too many disks missing" error but i realised i needed to start the array once with the erroring drive removed/unassigned.
 
After that, I:
stopped the array disabled array autostart, vms and docker shutdown the server took out the erroring 4tb drive installed one new 8tb started up the server set the new 8tb disk as parity set the old parity disk as an array member the "start" button confirmed that it would copy the parity from the old 4tb parity disk to the new 8tb after that completed (10 hours?), the array was started and the old parity disk was being rebuilt to replace the original erroring disk  
Once the old parity disk was rebuilt as an array member, i shutdown the server again and replaced another one of the 4tb drives (which had a few smart errors but was still working) with the second brand new 8tb drive.
 
Thats ticking away now.. gotta say i really do love unraid
