How to get active docs resident % back to 100% after rebalancing

Thank you–that is bad news, but is very helpful. I don’t recall ever running any kind of backup job. Is there a way to replace all nodes with no production downtime?

Our lead developer indicates the following: Couldn’t it be that docs (in our
case, really just objects since we’re using Couchbase as a distributed,
persistent key-value store only) that are no longer accessed were never
re-loaded after the re-balancing since they’re not being used/accessed? Because interestingly, our cache
miss ratio is essentially 0%, indicating that all of our read operations are
being satisfied by RAM.
