Registered by Zhi Yan Liu on 2013-09-03

Currently Cinder support client access volume with a particular mode: read-write (rw) and read-only (ro). So base on this feature Nova can allow user attach a read-only volume to an instance, and in future to attach a volume to multiple instance. For support this Nova need save block device's access mode information to block device mapping database table, it will be used to support volume information query by API (v2 and v3), manager such as instance's attached volume swapping handling.
