Drive not mounting into pool

[Kaitou-3D]

I had to replace my motherboard, everything was going well, but one of my three drives isn't in the array, but i can see the data on it via desktop and ssh.
lsblk -f:

It should be sda, sdb, and sdd in the pool.

Why do you think this has anything to do with mergerfs?

[Kaitou-3D]

Mainly cuz the fact that i can see that data for the drives individually, so my thought was that my config was messed up for mergerfs. If this is out of scope, I'll close this.

[trapexit]

You've just provided no evidence that it's mergerfs. mergerfs support page has details on what to include in a support request which includes a minimal example of the problem and showing runtime setup but you're just showing config which doesn't provide me with any information really to help.

[Kaitou-3D]

Sorry, that's on me for not reading that page, I came here from a google search. I'll close this and open a new one if i don't find a solution from the support page.

[trapexit]

You can just leave this open till you figure it out, that's fine. But the docs have a bunch of details so start there.

[Kaitou-3D]

Yep, this was a non issue. My fatab was misconfigured and the parts replacement caused the issue to surface. My bad chief.
