openstack中cinder中的nfs存储

在nfs 服务器共享数据卷

[ ~]# showmount -e
Export list for controller:
/cinder 192.168.15.201/24
/data 192.168.15.201/24

在cinder节点挂载共享卷

[ ~]# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/mapper/centos-root 300G 1.7G 299G 1% /

192.168.15.200:/cinder 498G 2.6G 495G 1% /home/nfsshare

修改cinder节点的配置文件

[ ~]# vim /etc/cinder/cinder.conf 

[DEFAULT]

enabled_backends = lvm,nfs

[nfs]
volume_driver=cinder.volume.drivers.nfs.NfsDriver
nfs_shares_config = /etc/cinder/nfsshare.conf
nfs_mount_point_base = /home/nfsshare
volume_backend_name = nfs

最后重新启动openstack-cinder-volume.service

systemctl restart openstack-cinder-volume.service
