You are assuming this is a one-way action. Some people may decide that checksums end up taking too much overhead or
similar,we should support disabling of this feature; with this proposed patch the disable action is fairly trivial to
handle.
Requesting an explicit checksum cycle would be desirable in the case where you want to proactively verify there is no
clustercorruption to be found.
