在MGR上安装必备软件

在 Ceph MGR 节点上安装 nfs-ganesha、nfs-ganesha-ceph、nfs-ganesha-rados-grace 和 nfs-ganesha-rados-urls 软件包

1
[root@serverc ~]# yum install nfs-ganesha nfs-ganesha-ceph nfs-ganesha-rados-grace nfs-ganesha-rados-urls -y

NFS Cluster Created Successfully

[root@serverc ~]# ceph nfs cluster info
{
    "nfsclustername": [
        {
            "hostname": "serverc.lab.example.com",
            "ip": "172.25.250.12",
            "port": 2049
        }
    ]
}

导出 CephFS 文件系统

格式是：

1
ceph nfs export create cephfs <fsname> <clusterid> <binding> [--readonly] [<path>]

我在nfs集群中，创建了/nfs1的路径
