What do you mean by mounting? Just restarting the array?

Nope, after that recover superblock comamnd, try again this:

mkdir /x

losetup -f --show -o 1048576 /dev/nvme0n1

then using the loop device you get from the command above, e.g., loop2

mount -v /dev/loop2 /x

If that doesn't give an error, then

btrfs fi usage -T /x

Still got:
"mount: /x: wrong fs type, bad option, bad superblock on /dev/loop5, missing codepage or helper program, or other error.

dmesg(1) may have more information after failed mount system call."
loop5 this time, I guess since I removed it and brought it back into the array to try to mount it with unassigned devices.
I'll see if i can use UFS Explorer otherwise I'll just wipe it. If i can't remember what was on it I probably won't miss it 😅
Thanks for the help!
