multiattach volume that has more than one\nread/write attachment, another server on the secondary attachment could\nbe writing to the volume which is not getting copied into the volume to\nwhich we\u0027re swapping, so we could have data loss during the swap.\n\nThis change does volume read/write attachment counting for the volume\nwe\u0027re swapping from and if there is more than one read/write attachment\non the volume, the swap volume operation fails with a 400 BadRequest\nerror.\n\nDepends-On: https://review.openstack.org/573025/\nCloses-Bug: #1775418\nChange-Id:
