Which operation preserves data and permissions when relocating a volume within a cluster?

• A. Volume move across nodes/aggregates preserves data and permissions
• B. Copy data manually
• C. Delete and recreate
• D. Reformat

Answer: (A)

Relocating a volume with a volume move in a NetApp cluster keeps everything intact because the operation moves the volume’s storage objects across nodes or aggregates without rewriting the data or reloading its metadata. The data blocks, file ownership, security ACLs, and POSIX permissions stay attached to the files as they exist, so users see the same files with the same permissions after the move. This is inherently non-disruptive and efficient since it avoids copying data through hosts. In contrast, copying data manually would require reading and writing every file to a new location, which not only takes much longer but can introduce window-for-change risks and potential permission or ACL discrepancies during the process. Deleting and recreating or reformatting would erase data and reset all permissions, defeating the purpose of a seamless relocation.
