Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Cause: Viostor driver doesn't reject write requests to read-only volume. Consequence: Attempt to format a read-only volume leads to qemu error. Fix: complete write requests with error if the target volume has read-only flag. Result: Attempts to format/write a read-only volume are rejected by viostor driver now.
