I have a few questions about Checksums.

Section 19.5.1 of the manual says:

To check the status of a wire checksum, run:

lctl get_param osc.*.checksums

Does that mean that clearing this parameter only clears the wire checksum?

Does writing each file named /proc/fs/lustre/osc/*/checksums do the same thing?

Is there a way to permanently disable checksums?

Thanks.
