【摘要】 解锁高效存储管理：OpenStack Cinder与NFS的完美结合

OpenStack Cinder 对接 NFS 后端存储

准备好磁盘

[root@cloud ~]# fdisk /dev/nvme0n3

Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x1d9ab064.

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p):

Using default response p.
Partition number (1-4, default 1):
First sector (2048-41943039, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-41943039, default 41943039):

Created a new partition 1 of type 'Linux' and of size 20 GiB.

Command (m for help): w
The partition table has been altered.

配置NFS服务

安装NFS

查询是否安装

[root@cloud ~]# rpm -qa |grep nfs
sssd-nfs-idmap-2.2.3-20.el8.x86_64
libnfsidmap-2.3.3-31.el8.x86_64

如果没有安装，执行以下安装命令

[root@cloud ~]# yum install -y nfs-utils

启动NFS服务

[root@cloud ~]# systemctl start nfs-server.service
[root@cloud ~]# systemctl enable nfs-server.service

关闭防火墙及SELinux

[root@cloud ~]# setenforce 0
[root@cloud ~]# vim /etc/selinux/config
[root@cloud ~]# 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
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted


[root@cloud ~]# systemctl stop firewalld.service
[root@cloud ~]# systemctl disable firewalld.service

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
192.168.129.141:/nfs_share

修改文件权限

[root@controller ~]# chown root:cinder /etc/cinder/nfs_share
