# 编辑配置文件

# 修改如下
filter = [ "a/sdc/", "a/sde/", "r/.*/"] # 过滤，，只用sdc磁盘
# 这里的sdc是用raid卡做的一块7TB的磁盘
pvcreate /dev/sdc /dev/sde # 加入物理磁盘
vgcreate cinder-volumes /dev/sdc /dev/sde # 创建cinder-volumes卷
apt -y install tgt thin-provisioning-tools # 带存储卷的精简功能
# 绑定target在storage network，（以下步骤可选，默认绑定在所有接口）
# 以下的配置不用执行，只是作为参考用，以下配置本人做了设置，但是还是没有在特定的IP 192.168.220.25上侦听3260端口，还望高手指点；（tgt服务默认在本机上侦听了所有接口。）
# vi /etc/init.d/tgt
# 修改如下
# --make-pidfile --background --exec --iscsi portal=192.168.220.25:3260 $DAEMON # 在start中，添加--iscsi portal=192.168.220.25:3260
# systemctl restart cinder-volume tgt # 服务开机自启动
3、在控制节点上验证
