cinder nfs配置操作

#####重启计算机服务

###cinder 节点操作 
yum install -y nfs-utils rpcbind

mkdir -p /data/nfs
 
echo ‘
/data/nfs *(rw,no_root_squash)
‘ >>/etc/exports

#all_squash：将远程访问的所有普通用户及所属组都映射为匿名用户或用户组；
#no_all_squash：访问用户先与本机用户匹配，匹配失败后再映射为匿名用户或用户组；
#root_squash：将root用户及所属组都映射为匿名用户或用户组；
#no_root_squash：来访的root用户保持root帐号权限；

systemctl enable rpcbind nfs
systemctl restart rpcbind nfs

systemctl reload rpcbind nfs

echo ‘[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
nfs_shares_config = /etc/cinder/nfs_shares
nfs_mount_point_base = $state_path/mnt
volume_backend_name=nfs_volumes
‘ >>/etc/cinder/cinder.conf
tail /etc/cinder/cinder.conf

sed -i ‘s/^enabled_backends.*=/enabled_backends=nfs,/g‘ /etc/cinder/cinder.conf
grep enabled_backends /etc/cinder/cinder.conf



echo ‘localhost:/data/nfs‘ >/etc/cinder/nfs_shares

chown root.cinder /etc/cinder/nfs_shares
chmod 640 /etc/cinder/nfs_shares
#chgrp cinder /etc/cinder/nfs_shares
systemctl restart openstack-cinder-volume.service 


####主节点 操作

source /root/admin-openrc.sh
cinder service-list |grep nfs

##创建云硬盘类型,关联volum NFS
cinder type-create nfs
cinder type-key nfs set volume_backend_name=nfs_volumes



#####删除 nfs 配置
sed -i ‘/[nfs]/,$d‘ /etc/cinder/cinder.conf
tail /etc/cinder/cinder.conf
sed -i ‘s/^enabled_backends = nfs,/enabled_backends=/g‘ /etc/cinder/cinder.conf
grep enabled_backends /etc/cinder/cinder.conf
rm -f /etc/cinder/nfs_shares


systemctl restart openstack-cinder-volume.service 

source /root/admin-openrc.sh
cinder service-list  |grep nfs
