You are not expected to modify cache contents yourself. Doing so
will likely cause various troubles - including not using the new
files placed into the cache after it was loaded from the disk, not
maintaining configured cache max_size and so on.
If you want to control cache contents yourself by syncing data
across machines, you may have better luck by using proxy_store
and normal files instead.
