Sorry I missed that sentence where you mentioned it was just if you restart the server.

And I agree it is an advantage that at least in this scenario no reboot is needed, for instance if you plan to upgrnde MongoDB version. Actually when you can plan the downtime it is usually simpler to handle in the general case of many cache hosts running at the same time when you can do the upgrade incrementally, but it is nice that a single big server can be upgraded without the problem of the cache reheating.

Apologizes again for not reading the article with more care.
