November 2, 20232 yr I had a sudden failure of my boot drive which (I'm guessing) caused the cache pool to get borked. When I replaced the boot USB disk, the system booted back up, but my cache pool (2 disks, btrfs pool) was offline and giving me unmountable errors. Following directions from here, I successfully mounted the pool to /temp and transferred all of the data to the array. I then added a spare SSD as a brand new one-disk pool, transferred /system, /appdata, and /domains to that new pool, and I'm up and running. However, both of the SSDs that were formerly part of the cache array are now seemingly permanently unmountable. I have tried removing them from the pool and re-adding them, to no avail. I've even gone as far as deleting the pool and trying to add them to a brand new pool, but that also doesn't seem to work. I've attached diagnostics. I fear that in my efforts to fix things, I've permanently messed up these two SSDs. What do you think? clappinator-diagnostics-20231101-2353.zip

November 2, 20232 yr Author Sorry, I should have been more clear. When I try to format the pool, I get errors and the drives are listed as unmountable and/or broken.
