`rbd map` maps rbd volume regardless if it's already mapped or not.[1] This patch is to prevent duplicated rbd map in connect_volume. [1] ``` root@compute-0:~# rbd -p rbd_ssd map foo /dev/rbd1 root@compute-0:~# rbd -p rbd_ssd map foo /dev/rbd2 ``` Change-Id: I13ef77edf31bffaecd671385cbca564931214a7e
