openstack 对接 NFS 存储

NFS 服务器端

1. 安装NFS服务

# yum install -y rpcbind nfs-utils

2. iptables端口设置

# iptables -I INPUT -p tcp --dport 111 -j ACCEPT

# iptables -I INPUT -p tcp --dport 2049 -j ACCEPT

# iptables -I INPUT -p udp --dport 111 -j ACCEPT

# iptables -I INPUT -p udp --dport 2046 -j ACCEPT

# iptables-save > /etc/sysconfig/iptables

3. 关闭防火墙

# systemctl stop firewalld.service

# systemctl disable firewalld.service

4. 启动nfs服务并设置开机自启动

# systemctl start rpcbind

# systemctl start nfs

# systemctl enable rpcbind.service

# systemctl enable nfs-server.service

5. 创建共享目录

# mkdir /home/nfsshares

# chmod 777 -R /home/nfsshares

6. 编辑exports文件，添加客户端

# vim /etc/exports

输入

/home/nfsshares *(rw,insecure,sync,no_root_squash)

7. 检查

# showmount -e 10.10.129.83

Export list for 10.10.129.83:

/home *

NFS 客户端

0。管理节点 创建存储类型：

# source keystonerc_admin

# cinder type-create nfs1

# cinder type-key nfs1 set volume_backend_name=nfs1

计算节点添加相关配置

1。修改 /etc/cinder/cinder.conf

(1) 添加

[nfs1]

nfs_used_ratio=0.95

nfs_oversub_ratio=1.0

volume_driver=cinder.volume.drivers.nfs.NfsDriver

nfs_shares_config=/etc/cinder/nfsshares

volume_backend_name=nfs1

(2) 修改并添加：

enabled_backends = ...,nfs1

2。/etc/cinder/nfsshares ：

(1) 添加

10.10.129.83:/home

(2) 修改文件属性：

# chown root:cinder /etc/cinder/nfsshares

# chown 0640 /etc/cinder/nfsshares

3。 重启cinder-volume服务

# systemctl restart openstack-cinder-volume.service
