Dell Unity：如何確認和設定 NFS 認證快取保留值

Summary: 當網路檔案系統 （NFS） 使用者請求存取匯出時，伺服器會從外部命名服務或本地檔案中檢索其憑據以對其進行身份驗證。之後，這些憑據將存儲在內部憑據緩存中。

預選賽 creditCacheRetention 指定憑據緩存刷新或超時的時間量（以分鐘為單位）。此參數的預設值為 15 分鐘。

以下命令驗證每個 NFS 匯出的詳細資訊：

15:23:40 service@FNMXXXXX spa:~/user# uemcli /net/nas/nfs show -detail

1:    ID                                = nfs_1
      NAS server                        = nas_1
      NFSv3 enabled                     = yes
      NFSv4 enabled                     = no
      Hostname                          =
      Secure NFS enabled                = no
      Kerberos Domain Controller type   =
      Service principal name            =
      Extended Unix credentials enabled = no
      Credentials cache retention       = 15m

2:    ID                                = nfs_2
      NAS server                        = nas_2
      NFSv3 enabled                     = yes
      NFSv4 enabled                     = no
      Hostname                          =
      Secure NFS enabled                = no
      Kerberos Domain Controller type   =
      Service principal name            =
      Extended Unix credentials enabled = no
      Credentials cache retention       = 15m

3:    ID                                = nfs_12
      NAS server                        = nas_12
      NFSv3 enabled                     = no
      NFSv4 enabled                     = yes
      Hostname                          =
      Secure NFS enabled                = no
      Kerberos Domain Controller type   =
      Service principal name            =
      Extended Unix credentials enabled = no
      Credentials cache retention       = 15m

 

接下來的指令將變更 Credentials cache retention 限定符並確認新值。對於此示例， nfs_1 已修改。

15:23:50 service@FNMXXXXX spa:~/user# uemcli /net/nas/nfs -id nfs_1 set -credCacheRetention 20

ID = nfs_1
Operation completed successfully.


15:28:27 service@FNMXXXXX spa:~/user# uemcli /net/nas/nfs -id nfs_1 show -detail

1:    ID                                = nfs_1
      NAS server                        = nas_1
      NFSv3 enabled                     = yes
      NFSv4 enabled                     = no
      Hostname                          =
      Secure NFS enabled                = no
      Kerberos Domain Controller type   =
      Service principal name            =
      Extended Unix credentials enabled = no
      Credentials cache retention       = 20m
