So? Do you think filesystem metadata is stored in a magical pixie cloud, or on the same unreliable physical hardware where it can easily get corrupted, especially after a crash or an unexpected power loss?

I posted this link here already:

f2fs (at least in its state a couple of years ago) is/was a prime example of how a filesystem can get into a barely working state with massive amounts of data and metadata corruption, and not even notice it.

God I love this site. In case of a minor disagreement with someone don't even bother to think, just press "downvote".

Corrupt data should be corrected by checksummed btrfs, isn't it?

Only if you have more than one copy of the data
