Issue

  • CREATE, LOOKUP, RENAME, and stat against one FlexGroup directory hang for 10 to 28 seconds.
  • NFS clients stall across multiple data LIFs at the same time, including compute nodes and a Slurm controller.
  • Hangs build while thousands of clients rename files in that directory and continue until that activity stops.
