Hi, noob here. 

I was away on a 2 week holiday and left my NAS running.  When I came back I realised my dockers were no longer running then realised I couldn't access appdata.  I naively thought a restart would fix it, went to stop the array and restart but stopping the array wouldn't work, it just hung so i just did an unsafe shutdown and power back on.  Now the SSD shows as "Unmountable: Wrong or no file system"



This SSD despite being brand new when inserted a year or so ago has been spitting out bad block errors for a while, I thought it had 1000s of reallocations left but I don't know.  It also shows as XFS, I'm a noob and thought the default was BTRFS, and being unknowledgeable would almost definitely have done default things.  

 

I've done a bit of searching and others have had similar problems but without the SSD degradation problems so I haven't tried those solutions.
Is there anyway I can rescue the data from this drive?
Thanks for any advice.

I've attached my logs and SSD smart health download

Cache device dropped offline, but you didn't post the new diags after the reboot to see the current problem.

Those diags were downloaded seconds before i posted.  I'm getting them from /boot/logs. is that not correct?

Edit: No it's not correct, I should have gone to tools->diagnostics.

Here's the latest.

Thanks

Cache device has a failed SMART test, so it needs to be replaced, if there's any important data there you can try to clone it with ddrescue to see if anything can be recovered.
