設定BeeGFS用戶端

您必須在需要存取BeeGFS檔案系統的任何主機（例如運算或GPU節點）上安裝及設定BeeGFS用戶端。在這項工作中、您可以使用Ansible和BeeGFS集合。

步驟

如有需要、請從Ansible控制節點設定無密碼SSH、並將其設定為BeeGFS用戶端的每個主機：

「sh-copy -id <user>@<hostname_or_ip>'」

在「host_vars/」下、為每個BeeGFS用戶端建立一個名為「.yml」的檔案、其中包含下列內容、並在預留位置文字中填入適合您環境的正確資訊：

# BeeGFS Client
ansible_host: <MANAGEMENT_IP>
# OPTIONAL: If you want to use the NetApp E-Series Host Collection’s IPoIB role to configure InfiniBand interfaces for clients to connect to BeeGFS file systems:
eseries_ipoib_interfaces:
  - name: <INTERFACE>
    address: <IP>/<SUBNET_MASK> # Example: 100.127.1. 1/16
  - name: <INTERFACE>0
    address: <IP>/<SUBNET_MASK>

目前、每個用戶端都必須設定兩個InfiniBand介面、兩個儲存IPoIB子網路各一個。如果針對此處列出的每個BeeGFS服務使用範例子網路和建議範圍、用戶端應該設定一個介面、範圍為「100127.1」。從0到100、127.99.255、另一個在100、128.1。0到100、128。99.255。

建立新檔案「client_inventory.yml」、然後在頂端填入下列參數：

# BeeGFS client inventory.
all:
  vars:
    ansible_ssh_user: <USER> # This is the user Ansible should use to connect to each client.
    ansible_become_password: <PASSWORD> # This is the password Ansible will use for privilege escalation, and requires the ansible_ssh_user be root, or have sudo privileges.
The defaults set by the BeeGFS HA role are based on the testing performed as part of this NetApp Verified Architecture and differ from the typical BeeGFS client defaults.

請勿以純文字儲存密碼。請改用Ansible Vault（請參閱的「Ansible」文件） "使用Ansible Vault加密內容"）或是在執行該教戰手冊時使用「Ask（隨叫隨到）」選項。

在「client_inventory.yml」檔案中、在「beegfs_clients」群組中列出所有應設定為BeeGFS用戶端的主機、然後指定建置BeeGFS用戶端核心模組所需的任何其他組態。

  children:
    # Ansible group representing all BeeGFS clients:
    beegfs_clients:
      hosts:
        ictad21h01:
        ictad21h02:
        ictad21h03:
        ictad21h04:
        ictad21h05:
        ictad21h06:
        ictad21h07:
        ictad21h08:
        ictad21h09:
        ictad21h10:
      vars:
        # OPTION 1: If you’re using the Mellanox OFED drivers and they are already installed:
        eseries_ib_skip: True # Skip installing inbox drivers when using the IPoIB role.
        beegfs_client_ofed_enable: True
        beegfs_client_ofed_include_path: "/usr/src/ofa_kernel/default/include"
        # OPTION 2: If you’re using inbox IB/RDMA drivers and they are already installed:
        eseries_ib_skip: True # Skip installing inbox drivers when using the IPoIB role.
        # OPTION 3: If you want to use inbox IB/RDMA drivers and need them installed/configured.
        eseries_ib_skip: False # Default value.
        beegfs_client_ofed_enable: False # Default value.

使用Mellanox OFED驅動程式時、請確定「beegfs_client_ofed_include_path」指向適用於Linux安裝的正確「標頭包含路徑」。如需詳細資訊、請參閱的BeeGFS文件 "RDMA支援"。

在「client_inventory.yml」檔案中、列出您要掛載在任何先前定義「vars」底部的BeeGFS檔案系統。

        beegfs_client_mounts:
          - sysMgmtdHost: 100.127.101.0 # Primary IP of the BeeGFS management service.
            mount_point: /mnt/beegfs    # Path to mount BeeGFS on the client.
            connInterfaces:
              - <INTERFACE> # Example: ibs4f1
              - <INTERFACE>
            beegfs_client_config:
              # Maximum number of simultaneous connections to the same node.
              connMaxInternodeNum: 128 # BeeGFS Client Default: 12
              # Allocates the number of buffers for transferring IO.
              connRDMABufNum: 36 # BeeGFS Client Default: 70
              # Size of each allocated RDMA buffer
              connRDMABufSize: 65536 # BeeGFS Client Default: 8192
              # Required when using the BeeGFS client with the shared-disk HA solution.
              # This does require BeeGFS targets be mounted in the default “sync” mode.
              # See the documentation included with the BeeGFS client role for full details.
              sysSessionChecksEnabled: false

「beegfs_client_config」代表已測試的設定。如需所有選項的完整概觀、請參閱netapp_eseries.beegfs`集合「beegfs_client」角色隨附的文件。這包括有關安裝多個BeeGFS檔案系統或多次安裝同一個BeeGFS檔案系統的詳細資料。

建立新的「client_playbook .yml」檔案、然後填入下列參數：

# BeeGFS client playbook.
- hosts: beegfs_clients
  any_errors_fatal: true
  gather_facts: true
  collections:
    - netapp_eseries.beegfs
    - netapp_eseries.host
  tasks:
    - name: Ensure IPoIB is configured
      import_role:
        name: ipoib
    - name: Verify the BeeGFS clients are configured.
      import_role:
        name: beegfs_client

如果您已在適當的IPoIB介面上安裝必要的IB/RDMA驅動程式和設定的IP、請省略匯入「NetApp_Eseries.host」集合和「IPoIB」角色。

若要安裝及建置用戶端和Mount BeeGFS、請執行下列命令：
```
ansible-playbook -i client_inventory.yml client_playbook.yml
```
在您將BeeGFS檔案系統置於正式作業環境之前、我們*強烈*建議您登入任何用戶端、然後執行「beegfs-fs-fs-checksfs」、以確保所有節點都可連線、而且不會報告任何問題。
