create fs_clone general

create fs_clone general


The create fs_clone general command is used to create a clone file system.


create fs_clone general name=? { parent_file_system_id=? | parent_file_system_id_list=? } [ parent_snapshot_id=? ] [ file_system_id=? ] [ number=? ] [ alloc_type=? ]





name=? Indicates the name of the clone you want to create.

The value consists of 1 to 255 ASCII characters including letters, digits, and underscores (_). However, when you create more than one file systems, the name must be no more than 251 characters.

parent_file_system_id=? Indicates the ID of the file system for which you want to create a clone.

To obtain the value, run "show file_system general".

parent_file_system_id_list=? Indicates the ID list of the file systems for which you want to create a clone.

To obtain the value, run "show file_system general".

parent_snapshot_id=? Indicates the ID of the snapshot.


file_system_id=? Indicates the clone file system ID.

The value is an integer between 0 and 65535. If the value is not specified, the system automatically allocates an ID of the newly created file system.

number=? Indicates the number of clone file systems that are batch created. If this parameter is specified, the "file_system_id=?" parameter cannot be specified.

The value ranges from 2 to 100. The default value is 1.

alloc_type=? Indicates the allocation type of the file system.

The value can be "thick" or "thin", where,

  • "thick": When thick file systems are created, fixed capacity is allocated to them.
  • "thin": Capacity of thin file systems will be automatically expanded when the capacity is about to be used up. The capacity cannot exceed the threshold (specified by the "capacity" parameter).
The default value is "thin".



Usage Guidelines

  • Before the operation, check whether the parent file system ID is correct.
  • Before the operation, check whether the clone file system name is correct or exists.
  • Multiple file systems can create clone file systems at the same time. Parent file system IDs are separated by commas (,).
  • Multiple clone file systems can be created for a file system.


Create a clone fs named clone1 for file system whose ID is 0.

admin:/>create fs_clone general name=clone1 parent_file_system_id_list=0
Create clone of file system clone1 successfully.
