• Zone: By default, the current zone is displayed.
• Name: Enter a name for the primary storage.

  The name must be 1 to 128 characters in length and can contain Chinese characters, letters, digits, spaces, hyphens (-), underscores (_), periods (.), parenthesis (), colons (:), and plus signs (+) and cannot begin or end with spaces.

• Description: Optional. Enter a description for the primary storage.
• Type: Select LocalStorage.
  Note:

  • If you select LocalStorage, the Cloud uses the hard disks of each host as a primary storage. LocalStorage primary storage can work with ImageStore and SFTP image storage. The total capacity of a LocalStorage primary storage is the sum of each host directory capacity.
  • If you attach multiple LocalStorage primary storage, make sure that each LocalStorage primary storage is deployed on an exclusive logical volume or physical disk.
• Mount Path: Enter the directory for mounting the LocalStorage primary storage.
  Note:

  • If the directory you entered does not exist, the Cloud automatically creates one.
  • The following system directories cannot be used. Otherwise, the hosts might fail to work properly.
    • /
    • /dev
    • /proc
    • /sys
    • /usr/bin
    • /bin
• Cluster: Select a cluster to which the LocalStorage primary storage is attached.

• Zone: By default, the current zone is displayed.
• Name: Enter a name for the primary storage.

  The name must be 1 to 128 characters in length and can contain Chinese characters, letters, digits, spaces, hyphens (-), underscores (_), periods (.), parenthesis (), colons (:), and plus signs (+) and cannot begin or end with spaces.

• Description: Optional. Enter a description for the primary storage.
• Type: Select NFS.
  Note: If you select NFS, ZStack Cube Ultimate automatically mounts the same NFS shared directory on all hosts as a primary storage. NFS primary storage can work with ImageStore and SFTP image storage, and can automatically mount the directory on all hosts.
• Mount Path: Enter the shared directory of the NFS server.
  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, 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 Option: Optional. To add mount options, make sure that these options are supported by the NFS server.
  Note:

  • The options 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 options, you can refer to the content in the -o option of mount.
  • You can set the options according to the mount command on commonly used clients. If the configured options conflict with the NFS server, the server shall prevail.

  Note:

  • If you have a dedicated storage network, enter its CIDR.
  • We recommend that you plan an independent storage network in advance to avoid potential risks. If you do not have an independent storage network, enter the network address according to your actual needs.
  • The Cloud uses the storage network to check the health status of VM instances.
• Cluster: Select a cluster to which the NFS primary storage is attached.

• Download and install the client tool mfsmount of MooseFS, and create a directory as the mount node.
• Assuming that the IP address of the MooseFS Master Server is 172.20.12.19, create /mnt/mfs as the mount point, and use the mfsmount command to mount the MooseFS system.
• You can also use the mfssetgoal command to set the number of file copies to be saved as needed.

[root@localhost ~]#mkdir /mnt/mfs 
[root@localhost ~]#mfsmount /mnt/mfs -H 172.20.12.19
[root@localhost ~]#mkdir /mnt/mfs/zstack
[root@localhost ~]#mfssetgoal -r 2 /mnt/mfs/zstack/
#The preceding commands mount the files in the /mnt/mfs/zstack/ directory to 172.20.12.19, and save two copies to the MooseFS storage server.
