Hello everyone! I have a little issue :(.
I have a "Cache pool" with two devices, SSD 250GB + SSD 240GB, in a mirror configuration. The 250GB disk had given me some trouble before; UNRAID asked me to format it. There was no issue since it was in "mirror mode" anyway. Days ago, after a restart, my cache appeared as Unmountable. I assumed the 250GB disk was causing issues again, so I left it as "unassigned." Everything returned to normal. So, my server has been running with only one SSD as cache... (yeah, my bad)
Well, I bought a new hard drive because I was running out of space (12tb HDD). (Before installing it, I made a backup of my flash drive, just in case)
I turned off the server, installed the 12TB disk, then turned the server back on, and the cache appeared as "Unmountable."
I tried the following:
"Stop array and unassign both pool devices
Start array (click checkbox "I want to do this")
Stop array
Reassign both pool devices"
Well, I'm not sure if I did it correctly. My pool consisted of two SSDs, but only one was working (240GB). I assumed that the "unassigned" option was the same as "no device."

Anyway, it didn't work, It still appears as "Unmountable."

Next, I tried this:
btrfs rescue zero-log /dev/sdb1

Then I restarted the array.
It didn't work.
I was running Unraid version 6.12.1, and I read that updating might fix it. I did update to version 6.12.6. It didn't work either.
I also tried this:
"btrfs check --readonly /dev/sdX1"

But I don't exactly understand what it means.
I hope you can help me; it would be a shame to lose all my configurations and dockers. English is not my native language, so I hope you understand what I wrote!
Greetings.
PD: Okay, the 250GB SSD works when I add it by itself. (Maybe an issue with the cable?) I was able to recover my dockers and configurations, but they are from several days ago. Well, better than nothing. If it were possible to recover anything from the other SSD, it would be wonderful.
PD2: Forget it, I managed to solve it with the working SSD. It was probably the cable. Issue resolved.
