snapshotId

Only extreme NAS is supported.

NOTE: A file system is created from a snapshot. The version of the created file system is the same as that of the snapshot source file system. For example, if the source file system version of the snapshot is 1 and you need to create A file system of version 2, you can first create A file system A from the snapshot, then create A file system B that meets the configuration of version 2, copy the data in file system A to file system B, and migrate the business to file system B after the copy is completed.
