Well the problem with such workaround-solutions is... end-users get
used to it, rely on it, and suddenly they don't work anymore (which the
user wouldn't probably notice, though).

Doesn't that fail for any multi-device setup, in which case btrfs reads
the blocks only from one device, and if that verifies, doesn't check
the other?
Cheers,

No. Srub reads the blocks from devices (without knowing which files own
them) and compares them to the stored checksums.

Hi,
Is it possible to confine scrubbing to a subvolume instead of the whole
file system?
The problem I am facing is that I have a 5 TB btrfs FS. On it I have
created subvolumes for weekly backups, personal photos, music, and
documents. Obviously, I am more concerned about my photos and document
