I noticed my 1 GB SSD cache drive was showing "Unmountable: No file system". I tried to use this guide I'm not sure I'm doing it right and I'm concerned I may screw something up.  Can someone ELI5 how to do this?  Here is my setup  I've also attached the diagnostics and the error log from SSD.  Thank you in advance.

That's your best bet.

 

P.S. syslog is spammed with errors like these:

And so useless.

@johnnie.black How do I get rid of those, so my syslog isn't useless.  

Look for a bios update.

thanks, Johnnie.black.  

 

I've tried the guide, but I'm not getting anywhere.  

 

can anyone help me with this guide and walk me through what each item should read

 

mkdir /x  what should x be?

 

mount -o recovery,ro /dev/sdf1 /x     I used sdf1, but again not sure what x should be

 

thanks a lot

it can just be x or any other name you want, it's just for a temporary mount point

Thank you for the quick response, I just tried that and got this error

mount: /x: can't read superblock on /dev/sdf1.

 

Do I need to have my array in maintenance mode?  

 

I really appreciate the help!

That means the superblock is damaged, try the mount -o recovery option and/or btrfs restore with a backup superblock, though a damaged superblock implies severe corruption, so recovery not so likely.
