最新版Ceph( Reef版本) nfs导出

1 创建一个nfs集群
ceph nfs cluster create <cluster_id> [<placement>]

# ceph nfs cluster create mycluster ceph-nfs-server 

2. 在ceph-164,ceph-165 host建立一个高可用的nfs
# ceph nfs cluster create mycluster --placement=ceph-164,ceph-165

3. 导出nfs集群
# ceph nfs export create cephfs --cluster-id mycluster --pseudo-path /my-nfs00/abc/data  --fsname cephfs01 --path=/ --squash no_root_squash

# 输出以下信息
{
  "bind": "/my-nfs00/abc/data",
  "cluster": "mycluster",
  "fs": "cephfs01",
  "mode": "RW",
  "path": "/"
}

# ceph fs ls
name: cephfs01, metadata pool: fs_kube_metadata, data pools: [fs_kube_data ]

#还可以导出你的配置
ceph nfs export info mycluster /my-nfs00/abc/data > my.json
#修改你的配置项
Vim my.json

# 更新你的配置
ceph nfs export apply mycluster -i my.json

最后客户端测试

# nfs挂载方式
mount -t nfs -o port=2049 192.168.0.164:/my-nfs00/abc/data /mnt/

# df -h | grep my-nfs
192.168.0.164:/my-nfs00/abc/data  222G     0  222G   0% /mnt
