------------------------------------
Thanks [~fishyds] for the comments; I formatted your message with the "code"
tags to make it easier to read.
For #1, let me try to see if that helps.
For #2, {{invokeSingle()}} already checks if the cluster is unavailable and
fails faster than usual if so (reduces the number of retries). Let me do some
performance check anyway.

> Currently mount points with multiple destinations (e.g., HASH_ALL) fail
> writes when the destination subcluster is down. We need an option to allow
> writing in other subclusters when one is down.
