Add Primary Storage | NFS

In the navigation pane of the ZStack Private Cloud UI, choose Hardware > Primary Storage. On the Primary Storage page, click Add Primary Storage. On the displayed Add Primary Storage page, set the following parameters:

• Zone: By default, the current zone is displayed.
• Name: Enter a name for the primary storage.
• Description: Optional. Enter a description for the primary storage.
• Type: Select NFS.
• URL: Enter the shared directory of the NFS server. Either an IP address or a domain is supported.
  Note:

  • Format: NFS_Server_IP:/NFS_Share_folder. For example, 192.168.0.1:/nfs_root.
  • You need to set the access permissions of the corresponding directories on the NFS server in advance.
  • To ensure security control on the NFS server side, we recommend that you configure corresponding security rules for access control.
  • You can check the shared directory of the NFS server by using the showmount -e command on NFS server in advance.
  • The following system directories cannot be used. Otherwise, the hosts might fail to work properly.
    • /
    • /dev/
    • /proc/
    • /sys/
    • /usr/bin
    • /bin
• Mount Parameter: Optional. Before you specify the mount parameters, make sure that these parameters are supported by the NFS server.
  Note:

  • The parameters are separated by commas (,). For example, nfsvers=3,sec=sys,tcp,intr,timeo=5. The preceding example means that the NFS server version is 3, the standard UNIX authentication mechanism is used, TCP is used as the transmission protocol, an NFS call can be interrupted in case of an exception, and the timeout is 0.5 seconds (5/10).
  • To specify the mount parameters, you can refer to the content in the -o option of mount.
  • You can set the parameters according to the mount command on commonly used clients. If the set parameters conflict with the NFS server side, the server side shall prevail.
• Storage Network: Indicate the storage network specified for the shared storage. The storage network can be shared by the management network of the management node.
  Note:

  • If you have an independent storage network, you need to enter the CIDR of the storage network.
  • You can use this storage network to check the health status of a VM instance.
• Cluster: Select a cluster to mount the primary storage.
