When you do a background fsck there is a point at which a snapshot of the filesystem is taken, although I'd say that happens at the beginning of the check. The problem is that with 5.3 Tb, it may take quite a while to take the snapshot, and during that time the system blocks any process that tries to write to the filesystem. Maybe that's what you are experiencing.
