Files with a Single Copy

This file system implementation maintains a single copy of files in the portal's file system. A change in the file system (addition, editing, and removal) generated at a cluster node is not replicated on other nodes, since the file system is shared among the cluster nodes.

Example: Imagine that a file from the portal's file system is written on the node Server1, and that later the same file is read on the other nodes in the cluster. In this case, the file would only be written by node Server1, and accesses to this file are made in local folders, as shown in the figure below:

File System Preparation

This file system implementation requires that the files be located in shared folders among the cluster nodes, as listed below:

• def: its root should be the folder <lumisdata>/shared/def
• data: its root should be the folder <lumisdata>/shared/data
• source: its root should be the folder <lumisdata>/shared/source
• static directories of websites: must be located in the same location configured in the Website Manager.
