September 1, 20232 yr Today I woke up to find 1 SSD of the 2 assigned to the cache missing. I disabled Docker, did a full shutdown then boot it up again. The array failed to start by itself, as 1 of the 2 SSD was still missing. I tried to start the array anyway and it did, with the cache still unavailable. Is it possible to recover data on the cache? There is only Docker appdata there, and I have weekly backups so it's not too bad if it's lost, but still would be nice to have the thing running until new SSDs arrive. Diags attached. tower-diagnostics-20230901-0935.zip

September 15, 20232 yr Author Hi JorgeB, thank you for your suggestion, and sorry about not replying until now. After a few hours that day, I decided to abandon the cache altogether and rebuild the Docker containers from the latest backup. Thanksfully that went well and the unraid box has been running nicely since then. Right now I have all shares (including appdata and system) running straight from the array, to avoid SSD shenanigans. 1 of the SSDs was indeed dead, so I just use the remaining one as a pure write cache now.
