6.5. 修改 Ceph 文件系统导出

流程

1. 根据伪根名称查看导出块：

   语法

   ceph nfs export get CLUSTER_NAME BINDING

   示例

   [ceph: root@host01 /]# ceph nfs export get nfs-cephfs /ceph
   {
     "export_id": 1,
     "path": "/",
     "cluster_id": "nfs-cephfs",
     "pseudo": "/ceph",
     "access_type": "RO",
     "squash": "none",
     "security_label": true,
     "protocols": [
       4
     ],
     "transports": [
       "TCP"
     ],
     "fsal": {
       "name": "CEPH",
       "user_id": "cephnfs11",
       "fs_name": "cephfs",
       "sec_label_xattr": ""
     },
     "clients": []
   }

2. 导出配置文件：

   示例

   [ceph: root@host01 /]# ceph nfs export get nfs-cephfs /ceph > export.conf

3. 编辑导出信息：

   语法

   {
     "export_id": EXPORT_ID,
     "path": "/",
     "cluster_id": "CLUSTER_NAME",
     "pseudo": "CLUSTER_PSEUDO_PATH",
     "access_type": "RW/RO",
     "squash": "SQUASH",
     "security_label": SECURITY_LABEL,
     "protocols": [
       PROTOCOL_ID_
     ],
     "transports": [
       "TCP"
     ],
     "fsal": {
       "name": "NAME",
       "user_id": "USER_ID",
       "fs_name": "FILE_SYSTEM_NAME",
       "sec_label_xattr": ""
     },
     "clients": []
   }

   示例

   [ceph: root@host01 /]# vi export.conf
   
   {
     "export_id": 1,
     "path": "/",
     "cluster_id": "nfs-cephfs",
     "pseudo": "/ceph",
     "access_type": "RW",
     "squash": "none",
     "security_label": true,
     "protocols": [
       4
     ],
     "transports": [
       "TCP"
     ],
     "fsal": {
       "name": "CEPH",
       "user_id": "cephnfs11",
       "fs_name": "cephfs",
       "sec_label_xattr": ""
     },
     "clients": []
   }

   在上例中，access_type 从 RO 修改为 RW。

4. 应用规格：

   语法

   ceph nfs export apply CLUSTER_NAME PATH_TO_EXPORT_FILE

   示例

   [ceph: root@host01 /]# ceph nfs export apply nfs-cephfs -i export.conf
   Added export /ceph

5. 获取更新的导出信息：

   语法

   ceph nfs export get CLUSTER_NAME BINDING

   示例

   [ceph: root@host01 /]# ceph nfs export get nfs-cephfs /ceph
   {
     "export_id": 1,
     "path": "/",
     "cluster_id": "nfs-cephfs",
     "pseudo": "/ceph",
     "access_type": "RW",
     "squash": "none",
     "security_label": true,
     "protocols": [
       4
     ],
     "transports": [
       "TCP"
     ],
     "fsal": {
       "name": "CEPH",
       "user_id": "cephnfs11",
       "fs_name": "cephfs",
       "sec_label_xattr": ""
     },
     "clients": []
   }
