Mount Management

Glossary

• Mount: The operation of connecting cluster nodes to a file system. After a mount is created, compute nodes can access the data in the file system.

• Mount Point: The entry directory on a cluster node where the file system is mounted.

• Shared Directory: The directory exported (shared) by the file system.

• Source Address: The file system IP address plus the shared directory.

• Global/Partition Mount: Global mount records apply to the whole partition; partition mounts apply only to a specific partition. You can upgrade a partition mount to a global mount, or convert a global mount to a partition mount.

  • Example:

    	Source address	Shared directory	Mount point	Protocol	Mount options
    Mount record	192.168.1.1:/fastone	/fastone	/mnt	NFS	v3,lock

  Multiple mount records are referred to as a mount list.
