Hi Otto,

Is anyone using this feature in production and can comment on it?

Are there best practices regarding the usage of this feature?

Any caveats to be aware of, such as overhead, latency, long-term
maintainability?

File and directory layouts work very good in production. We are supporting several installations where that feature is used.

Best is to start with an empty directory that gets 'layout' to the new pool as existing files will not be moved when changing that attribute.

You will have to copy existing files to the new directory (and therefor the new pool). An "mv" will not change the pool.
