Describe the solution you'd like

• Directly obtain and display the extent information of the file through the existing interface topo/get, getExtentsByInode, etc. (supports pagination, and some inodes have larger extents)

Additional context
When the current network reads and writes abnormally. We generally query the mp partition to which it belongs through the id value of the inode, and then use the metanode interface to specify the mp partition id to query metadata information (extent list and dp)
