    Description

      Several presentations at RUG'16 mentioned that Lustre has poor performance when there are very large numbers of HSM actions outstanding on the coordinator.

      Firstly, having a /proc file that exposes the number of entries currently in the HSM action list would allow RBH and monitoring scripts to easily monitor the number of enties.
