So... Is the background fsck causing damage or corruption? The answer
to that is NO. It's a consequence of reading a bad directory
structure, which happened anyway.

Quoting jpd on this same issue, emphasis added:

Seriously, this conversation is full of crap, and only makes one of
FreeBSDs incredibly useful features look bad with no evidence. Can
no-one can come up with a reply either quoting a mailing list or
giving the circumstances when:

a) Background fsck caused data CORRUPTION

_and_

b) A foreground fsck would not have done the same

?

Anything else is sidestepping the question, and spreading FUD.

Anyone?

Perhaps I should CC one of the filesystem developers to get them to
reassure you all? I don't think they'd be too pleased at people saying
their design is flawed. It's not.
