Hello, Completely at random sometime tonight, perhaps during my monthly parity check my cache disk went boom. I was able to use dockers earlier in the evening but sometime after midnight I tried to use a docker and it was offline. I was unable to stop/start/restart containers so I stopped Docker service and could not restart. So I turned it off and on again I did a reboot of Unraid. Once the server was back online the cache disk showed Unmountable: Unsupported or no file system. I tried to fix it myself following guidance elsewhere on these forums but ran into an error so I'm reaching out for helppies. Here is the output of what I attempted to do, also Attached is the diagnostics. ----------- oot@Magnetar:~# sfdisk /dev/nvme0n1 Welcome to sfdisk (util-linux 2.38.1).
