Unmounting Storage Domains

Unmounting Storage Domains

When an OceanStor 9000 cluster is brought offline or deleted, the storage resources of the cluster must be deleted from the global namespace of the UniformView client.

Context

The umount command or del command can be used to unmount storage domains from the UniformView client. Running the umount command, you can unmount multiple storage domains from the UniformView client through the configuration file. Running the del command, you can unmount only one storage domain from the UniformView client at a time in the following format: Mounting name#Shared directory#Cluster dynamic service IP address.

Procedure

  • Use the umount command

    1. Log in to the UniformView client as the root user.
    2. In the installation directory, create an .ini UniformView configuration file.

      vi UniformView.ini

    3. Write the mounting name, shared directory name, and cluster dynamic service IP address of each storage domain in the configuration file in the format of Mounting name#Shared directory name#Cluster dynamic service IP address. The following provides an example:
      C20_001#NFS_DirA#192.168.1.10
      C20_002#NFS_DirA#192.168.1.20
      C20_003#NFS_DirA#192.168.1.30
    4. Run the umount command.

      UniformView umount /home/UniformView.ini In the command, /home/UniformView.ini is the absolute path of the UniformView configuration file.

      # UniformView umount /home/UniformView.ini
      umount success
    NOTE:

    You can use command UniformView umountall to unmount all storage domains. In this case, the configuration file is not needed anymore.

  • Use the del command

    1. Log in to the UniformView client as the root user.
    2. Run a del command to unmount a storage domain from the UniformView client.

      UniformView del Mounting name#Shared directory#Cluster dynamic service IP address

      # UniformView del C20_001#NFS_DirA#192.168.1.10
      del success!

Verification

  1. Log in to the UniformView client as the root user.
  2. View the mounting root directory /mnt/UniformView to check whether the shared directory is deleted. If the shared directory fails to be deleted, check the UniformView configuration file and try again.
