What kind of snapshot?

AFAIR from old days with netapp, snapshots on netapp expose the same
inode. diff will see this and will not further look at the file, even if
everything else is different - size, timestamps etc. I guess it's still
the same today.

To answer your question, you might be looking for 'hosted-engine
--reinitialize-lockspace'. But if you ask me, if the content was zeroed,
you have some serious issues there - either on the storage or on the
hosts.

Good luck.

Note that dd and/or the shell might too refuse to copy over the "same"
file (same inode).

Best,
