Because the container files themselves are files in the filesystem, there is no notion or "construct" for a mount point. Read access to the containers is managed via normal read semantics to a "file" as provided by the filesystem. And the server manages the 'write' behaviors so that things behave correctly with multiple sessions/writers in-flight at a given time. > > > > Þ Or the equivalent command of Q NODEDATA nodename for nodename > on stg container ? Not applicable to container pools. The Q NODEDATA provided visibility to data placement on "volumes" in order to help with understanding what volumes would be needed at the time of restore or how well collocation is working. Container pools are built and optimized for deduplicated data - namely chunks (or extents as we reference in the documentation). As such, we would expect the data for a given client node to be distributed across many containers. If the Q NODEDATA is of interest in planning for restore, this is not needed for container based pools as access to the chunks is simply needed and those chunks can be throughout the pool. Also, collocation does not apply for container pools - again because data is managed at the level of chunks which are expected (or at least likely to) span use by many different nodes. > > > Regards Robert >
