EXAMPLES
      To check the file system whose ID is "0", speed is "high", forcible check tag is "yes", range is "all", check integrity tag is "yes", run the following command.
              developer:/>change space check_space_consistency file_system_id=0 speed=high force=yes range=all check_integrity=yes
              DANGER: You are about to check the file system or LUN. When performing this operation, note the following:
              1. During checking the file system or LUN, do not perform other operations on the storage system or the file system or the LUN.
              Suggestion: Confirm that you want to check the file system or LUN before running the command.
              Have you read danger alert message carefully?(y/n)y
              Are you sure you really want to perform the operation?(y/n)y
              Command executed successfully.
		
      Update the value of background task identifiers of the file system and the LUN to the memory.
              developer:/>change space config type=update_backgroud_task_switch controller=0A
              Command executed successfully.
		
      Enable emergency space in file system "0".
              developer:/>change space grain controller=0A file_system_id=0 switch=on
              DANGER: You are about to run a command to set the switch of emergency space in the file system. After the switch is turned on, emergency space of the file system will be used. The faulty file system may fail to be repaired after the emergency space is used up.
              Suggestion: Before running this command, ensure that you have selected the correct file system.
              Have you read danger alert message carefully?(y/n)y
              Are you sure you really want to perform the operation?(y/n)y
              Command executed successfully.
		
      Add an extent tree for file system "0".
              developer:/>change space grain_extent_tree controller=0A file_system_id=0
              Command executed successfully.
		
      Add a merge tree for file system "0".
              developer:/>change space grain_merge_tree controller=0A file_system_id=0 switch=on
              Command executed successfully.
		
      Set the "force_stop_lun_rescue_task" configuration parameter of the rescue to "1".
              developer:/>change space rescue_config controller=0A key=force_stop_lun_rescue_task value=1
              DANGER:You are about to configure the operating parameters of the rescue task for the file system and deduplication and compression LUN.
              1. The configured parameters take effect in the memory only. 
              2. Incorrect configurations may lower the rescue speed or compromise performance.
              Suggestion:
              1. Before performing this operation, run the command to configure parameters (except the "force_stop_lun_rescue_task" and "force_stop_fs_rescue_task" parameters) of the rescue task for the file system and deduplication and compression LUN.
              2. Enter the working controller ID for the controller ID.
              Have you read danger alert message carefully?(y/n)y
               
              Are you sure you really want to perform the operation?(y/n)y
              Command executed successfully.
		
      Set the "force_stop_fs_rescue_task" configuration parameter of the rescue to "1".
              developer:/>change space rescue_config controller=0A key=force_stop_fs_rescue_task value=1
              DANGER:You are about to configure the operating parameters of the rescue task for the file system and deduplication and compression LUN.
              1. The configured parameters take effect in the memory only. 
              2. Incorrect configurations may lower the rescue speed or compromise performance.
              Suggestion:
              1. Before performing this operation, run the command to configure parameters (except the "force_stop_lun_rescue_task" and "force_stop_fs_rescue_task" parameters) of the rescue task for the file system and deduplication and compression LUN.
              2. Enter the working controller ID for the controller ID.
              Have you read danger alert message carefully?(y/n)y

      Delete the extent tree of a file system.
              developer:/>delete space grain_extent_tree type=file_system
              DANGER: You are about to delete extent trees from file systems or LUNs. Before performing this operation, note the following:
              1. Only the extent trees automatically constructed after the system upgrade can be deleted.
              2. After the extent trees are deleted, the space extent consistency check fails.
              3. After the extent trees are deleted, the maximum number of consistency point rollbacks changes to 5.
              4. The deletion is implemented in the background. The execution duration is affected by workloads and data volumes. You can run the query command to query whether the deletion is complete.
              Suggestion: Before performing this operation, ensure that the extent trees need to be deleted from the file systems or LUNs.
              Have you read danger alert message carefully?(y/n)y
              Are you sure you really want to perform the operation?(y/n)y
