      Description

      If OSTs are permanently deactivated via lctl conf_param <fsname>.OSTnnnn.active=0 they still appear in the lfs df output, which can be annoying to users.

      lfs df
      UUID                   1K-blocks        Used   Available Use% Mounted on
      myth-MDT0000_UUID        9174328     1213448     7436592  14% /myth[MDT:0]

      myth-OST0002_UUID     3880285544  3555131444   208731780  94% /myth[OST:2]
      myth-OST0003_UUID     5840741952  4523261952  1025405712  82% /myth[OST:3]
      OST0004             : inactive device
      
      filesystem summary:  17487365048 15019461204  1671055644  90% /myth
      

      If the OST is permanently deactivated (as opposed to disconnected or otherwise unavailable due to error) don't list the OST in lfs df unless -v is also given. That will remove this annoying output from normal usage, but still allow the full OST listing to be generated if needed for some reason.
