I'm assuming with both of these showing inconclusive that the SSD cache array is borked.

Basically yes, looks like both file systems existed at some point in the past but none is recoverable, at least not with the standard filesystem tools, data might be recoverable with a file recovery util, like UFS explorer.

If I don't have a backup of the appdata, do I just have to rebuild the docker apps, etc? I didn't have too much but is annoying is all.

 

Also to prevent a failure like this in the future, what is recommended to protect the appdata? Is there a way to mount an external usb drive and have things copied there?

I apologize for keeping the thread going, just new to unraid and looking for any help if possible.
