I don’t see any relevant reads on this issue at this time.

Well I do find a lot of posts on surface 3 - have you read through all of those?

It does - in some cases. There’s been a lot of discussion in the forums about RAID and fog - I would suggest you search the forums for “raid” and read through the threads that are under a year old.

The first and easiest thing to try is the kernel argument that specifies raid. I think it’s mdraid=1 but I may be wrong, it’s been a while. Search the forums.
