    Description

      Similar idea of fstrim, use SSD as backend of Lustre filesystem might have performances
      drop with gc running in the background.

      We have mount option '-o discard'(etc) for ldiskfs to trigger discard automatically
      whenever filesystem free some space, but as our benchmarking this could
      introduce latency too, and also this is somehow out of control.

      So it is desirable for administrators to do trim manually, for example
      doing trim if system are idle.
