              1. When rescuing the file system, do not perform other operations on the storage system or the file system.
              2. Rescuing the file system may cause file data loss and disk space leakage. Exercise caution when rescuing the file system.
              3. The rescuing function only rescues files, directories, and extended attributes of files and will clear the data of value-added features (such as file system replication, snapshot, quota tree, and quota) on the file system. 
              4. The rescuing function may rescue deleted files, directories, or data. 
              5. After a successful rescuing, the available space of the file system may be greater than, equal to, or smaller than that before the rescuing. 
              6. After a successful rescuing, the space occupied by the file system may be greater than the amount of data that can be accessed. 
              7. After the command is executed successfully, run the show command to view the status and progress of the rescuing task. 
              8. After successfully rescuing the file system, you must run the command to confirm the rescuing action.

      Enable the space exhaustion protection function of the file system "1".
              developer>change file_system optimization file_system_id=1 name=space_exhaust_protect enable=yes
              DANGER: You are about to turn on the switch of protecting file system space from being used up. Before performing this operation, note the following:
              1. After the switch is turned on, files cannot be created and data cannot be written to files when the remaining capacity of the file system is insufficient. Under such circumstances, you can only delete and read data. After files or file data is deleted and the remaining capacity of the file system becomes sufficient, files and data can be written to the file system again.
              2. The remaining capacity of a file system depends on the capacity allocated to the file system and the size of the used capacity.
              3. After the switch is turned on, the following circumstance is normal: A message indicating insufficient capacity is displayed upon client operations, but the query result shows that the file system has remaining capacities.
              Suggestion: Before performing this operation, ensur that the switch needs to be turned on for the file system. 
		
      Disable the space exhaustion protection function of the file system "1".
              developer>change file_system optimization file_system_id=1 name=space_exhaust_protect enable=no
              DANGER: You are about to turn off the switch of protecting file system space from being used up. Before performing this operation, note the following:
              1. After the switch is turned off, the access to the file system will become slow when the remaining capacity of the file system is small. After files or file data is deleted and the remaining capacity of the file system becomes sufficient, the access speed becomes normal.
              Suggestion: Before performing this operation, ensure that the switch needs to be turned off for the file system.

              1. If the specified file system capacity is less than or equal to 3 GB, value-added services, host services, and switching the working controller of the file system may time out. 
              2. If the value of the file system's "auto_delete_enabled" parameter is set to "yes", this operation deletes outdated files from the file system. 
              3. If the value of the file system's "auto_delete_snapshot_enabled" parameter is set to "yes", this operation deletes read-only snapshots from the file system when the file system space is about to be used up. 
              Suggestion: 
              1. Before performing this operation, select a proper file system space. It is recommended that the file system space be greater than 3 GB. 
              2. Before performing this operation, ensure that you select a correct file system and read-only snapshots under the file system can be deleted.

              DANGER: You are about to check the file system. When performing this operation, note the following:
               
              1. When checking the file system, do not perform other operations on the storage system. 
               
              2. Before executing a deduplication metadata clearing policy, disable periodic snapshot. Otherwise, data may be inconsistent. 
               
              3. The deduplication metadata clearing policy clears all deduplication metadata and causes the leakage of some disk space. This operation is irreversible. Perform this operation only when deduplication metadata is damaged. 
               
              4. The deduplication metadata clearing policy creates a snapshot. Do not delete the snapshot. Otherwise, data may be inconsistent.
               
              5. After a deduplication metadata clearing policy is executed, do not enable periodic snapshot, delete an existing snapshot, or roll back a snapshot. Otherwise, data may be inconsistent.
               
              6. The deduplication metadata clearing policy interrupts host I/Os. 
               
              7. The deduplication metadata clearing policy clears the statistics on space saved by deduplication and compression and affects the subsequent data deduplication ratio. 
               
              8. If a chunk ID is specified for the deduplication metadata clearing policy, ensure that the chunk ID is correct. Otherwise, data may be inconsistent. Contact R&D engineers for confirmation. 
               
              Suggestion: Perform this operation based on customer requirements.

              WARNING:You are about to change the vStore to which the file system belongs. Pay attention to the following points:
              If NAS share, antivirus, HyperMetro, or SmartTier services are configured for the file system, delete these services before changing the owning vStore.
              Suggestions:
              1. After the owning vStore is changed, check whether NAS share, antivirus, HyperMetro, or SmartTier services of the file system exist in the original vStore. If yes, delete them.
              2. After the owning vStore is changed, reconfigure NAS share, antivirus, NDMP, HyperMetro, or SmartTier services for the file system.
              Have you read warning message carefully(y/n)y
