Possible Cache Pool Issue

Hey folks,

 

My cache consists of 2 1TB SSDs in a RAID1 BTRFS pool. The main GUI shows 0 errors on both drives, however my log is telling a different story...

This error repeats constantly.

 

I ran a scrub on the cache which shows 4 uncorrectable errors. Strangely enough the main GUI still shows 0 errors and I've not noticed any other symptoms.

 

How do I go about fixing this?

I'm not by any means a BTRFS expert so I'll refer you to a post written by a guy who is. I believe you're going to have to backup as much data as you can, reformat and then restore it.
