Cinder对接NFS

Clinder组件

#创建卷顺序

cinder-api：      接收创建云主机存储资源请求         #控制节点
cinder-scheduler：计算调度
cinder-volume：   真正创建的组件
driver：          存储的驱动                        #存储


#附加挂载卷顺序
nova-api:       接收外部请求                        #控制节点
nova-scheduler: 计算调度
nova-compute:   发放虚拟机
nova-driver:    驱动 

计算节点
/etc/libvirt/qemu/i-0004.xml 定义磁盘文件（搜disk）

控制节点把磁盘挂载给计算节点物理机，通过文件映射到 虚拟机ECS01

Cinder对接NFS

NFS服务端

#NFS服务端
[root@nfs ~]# yum -y install rpcbind  nfs-utils	  
[root@nfs ~]# mkdir /opt/nfshare
[root@nfs ~]# chmod 777 -R /opt/nfshare
[root@nfs ~]# vim /etc/exports
	/opt/nfshare  192.168.10.0/24(ro,sync)  
	
[root@nfs ~]# systemctl stop firewalld
[root@nfs ~]# systemctl disable firewalld 
[root@nfs ~]# setenforce 0
[root@nfs ~]# systemctl restart  nfs-server.service  	
[root@nfs ~]# systemctl enable nfs-server.service

客户端

[root@controller ~(keystone_admin)]# mount -t nfs 192.168.10.12:/opt/nfshare  /media	         

#创建新的后端参数（openstack控制端）
[root@controller ~(keystone_admin)]# vim /etc/cinder/nfs_share
