E.3 Adding a Slave Server/Scaling Out

Under a DFS, the server processing performance can be improved by adding slave servers to scale out the system.

The slave servers, development servers and collaboration servers can be added without stopping operation.

Note

After deletion of the slave servers, development servers and collaboration servers, servers cannot be added while operation continues.

In this case, unmount the DFS and then add the servers.

The slave server, development server and collaboration server addition procedure is described below using the following environment as an example:

Logical file system name:	pdfs1
Mount point:	/mnt/pdfs
Representative partition:	/dev/disk/by-id/scsi-1FUJITSU_300000370106
File system ID:	1
Master server:	master1, master2
Existing slave server, development server, collaboration server:	slave1, slave2, slave3, slave4, slave5, develop, collaborate
Additional slave server:	slave6, slave7, slave8, slave9, salve10
