创建NFS导出目录

在任意一个该Ceph集群的 cephfs 客户端节点，进入cephfs的挂载点创建一个需要导出的目录

假如需要导出iso目录，需要确保/cephfs存在，如没有则需要创建

df -h |grep cephfs
10.0.0.56:6789,10.0.0.57:6789:/   59T  328G   59T   1% /cephfs
cd  /cephfs
mkdir  iso

mds节点操作

10.0.0.57 mds节点

安装ganesha相关包

yum install -y nfs-utils nfs-ganesha nfs-ganesha-ceph

rpm -qa |grep ganesha
nfs-ganesha-2.7.4-10.el7cp.x86_64
nfs-ganesha-ceph-2.7.4-10.el7cp.x86_64

rpm -ql nfs-ganesha
/etc/ganesha/ganesha.conf
/usr/lib/systemd/system/nfs-ganesha.service
...

配置

vi /etc/ganesha/ganesha.conf
