Problem with Pool

[GAxelsson]

TrueNAS core (TrueNAS-12.0-RELEASE), system is running on a Intel(R) Xeon(R) CPU E5-1620 0 @ 3.60GHz with 64 GB of RAM

Just lost "Pool-1" due to SSD (cache) going offline (The disk was in "MISSING" state before reboot):

I need to remove the cache before attempting to mount the volume again.

I keep getting these "no such pool" when I try to remove the faulty cache. I have googled a lot and I keep returning to commands that ends with the error "no such pool".

Please advice me on how to solve this issue.

Screenshot below shows the disks in the system.

It is a bit strange that the zpool command states that "Pool-1" is "ONLINE" as shown in the first screenshot. Could that be the reason why it doesn´t allow me to remove the "faulty" device (the cache SSD)?

Please, I need your help. It seems like a catch-22:

Ok, I succeeded mounting the lost pool using the command below:

There is obviously more work that needs to be done, but at least I can access all files in the pool.

There's an import option which will drop the SLOG and L2ARC... -m if I remember right...

checking it here makes clear that it's only for SLOG, but may still do the trick.
