Understood, I certainly wasn’t questioning the wisdom of the question or reasoning, it
makes logical sense, unfortunately I am unable to remove the new controller at this point.
I will have to schedule an outage
I'm assuming you still have remote access to the computer. Try "cat
/proc/partitions" to see what drives the kernel sees. Then do "fdisk
-l" on each one to see if you can find your partitions.

Good point.
This is easy to fix if you do find the right partition. Use blkid to
get the UUID of the filesystem, then edit the fstab.
