IIRC clear_cache will only clear the cache of modified block groups for v1 space cache. And that's why we have btrfs check --clear-space-cache v1, which will wipe out all (v1) space cache.

Just checked, and mounting with clear_cache, and then re-fscking doesn't even fix the problem... Output stays the same. Cheers, Chris. smime.p7s Description: S/MIME cryptographic signature

Thought that should work with recent kernels could that mean some data will be corrupted when I do e.g. mount with clean_cache? Interestingly, $? is still 0... even though errors were found. And kernel log shows nothing. Cheers, Chris. smime.p7s Description: S/MIME cryptographic signature
