cinder对接NFS后端存储

配置NFS服务
安装NFS服务
查询是否安装
[root@nfs ~]# rpm -qa |grep nfs
nfs-utils-1.3.0-0.8.el7.x86_64
如没有安装，执行以下命令
[root@nfs ~]# yum install -y nfs-utils
关闭防火墙及SELinux
[root@nfs ~]# setenforce 0
[root@nfs ~]# vi /etc/selinux/config
[root@nfs ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@nfs ~]# systemctl stop firewalld
[root@nfs ~]# systemctl disable firewalld
创建共享目录
[root@nfs ~]# mkdir /nfs_share
[root@nfs ~]# lsblk

[root@nfs ~]# chmod -R 777 /nfs_share/
修改配置文件
[root@nfs ~]# vi /etc/exports
[root@nfs ~]# cat /etc/exports
/nfs_share 192.168.100.0/24(rw)
## 重启服务
```bash
[root@nfs ~]# systemctl restart nfs-server.service
客户端测试挂载
使用控制节点测试挂载
[root@controller ~]# rpm -qa|grep nfs
nfs-utils-1.3.0-0.8.el7.x86_64
libnfsidmap-0.25-11.el7.x86_64
[root@controller ~]# systemctl start nfs
[root@controller ~]# mkdir /nfs_test
[root@controller ~]# mount -t nfs 192.168.100.40:/nfs_share /nfs_test
[root@controller ~]# df -hT

[root@controller nfs_test]# touch {a,b}{1,2}.txt
[root@controller nfs_test]# ls
a1.txt a2.txt b1.txt b2.txt
[root@controller ~]# umount /nfs_test/
控制节点配置NFS共享
创建文件并配置
[root@controller ~]# vim /etc/cinder/nfs_share
[root@controller ~]# cat /etc/cinder/nfs_share
192.168.100.40:/nfs_share
修改文件权限
[root@controller ~]# chown root:cinder /etc/cinder/nfs_share
[root@controller ~]# chmod 0640 /etc/cinder/nfs_share
[root@controller ~]# ll /etc/cinder/

创建新的后端定义
增加 NFS 后端参数
增加 nfs 后端参数，其中 lvm 默认存在，nfs 为新增
[root@controller ~]# vim /etc/cinder/cinder.conf
[root@controller ~]# cat /etc/cinder/cinder.conf
enabled_backends=lvm,nfs
[lvm]
iscsi_helper=lioadm
volume_group=cinder-volumes
iscsi_ip_address=192.168.100.10
volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver
volume_backend_name=lvm
[nfs]
nfs_shares_config=/etc/cinder/nfs_share
volume_driver=cinder.volume.drivers.nfs.NfsDriver
volume_backend_name=nfsbackend
