BTRFS error (device loop2): parent transid verify failed on 148996096 wanted 1692344

Seems like my cache is dying - can you please help me plan out what to do?

 

Log is flooded with these messages:

BTRFS error (device loop2): parent transid verify failed on 148996096 wanted 1692344

 

Attached my diagnostics.

 

I'l guessing I need to try and get everything off the cache and reformat it - are there some good steps for follow for that?

 

Thanks

loop2 is the docker image, it needs to be recreated, it likely got corrupt because according to these errors one of the cache devices dropped offline in the past:

 

May  9 14:11:47 unraid-2 kernel: BTRFS info (device dm-13): bdev /dev/mapper/sdi1 errs: wr 37591, rd 21008, flush 1044, corrupt 1187, gen 0

 

You should run a scrub now and monitor for future issues, see here.
