4.3.2 DFS Setup

Mount point creation

Create the mount point for mounting a disk partition at the storage system used as the DFS.

Make the mount point the same as the mount point specified at the master server.

Example

Create mount point "pdfs" under "/mnt".

# mkdir /mnt/pdfs <Enter>

fstab settings

In "/etc/fstab", define the mount point created above and the logical file system name.

The logical file system name is used to identify the DFS file system. Use the name defined when generating the configuration information of the file system on the master server.

Example

This example shows the mount point "/mnt/pdfs" and the logical file system name "pdfs1" defined at "/etc/fstab".

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/home             /home                   ext3    defaults        1 2
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-sda3         swap                    swap    defaults        0 0

pdfs1                   /mnt/pdfs               pdfs    _netdev         0 0

The "DFS file configuration information" must be distributed to the slave server before the DFS file system is mounted. Refer to "3.1.5 Distributing the DFS File System Configuration Information" if the "DFS file configuration information" is not yet distributed.

Refer to "D.4.6 Mount" in "Appendix D DFS Environment Construction" for information on mounting a DFS file system.

Example

Mount the DFS file system at the slave server.

# mount pdfs1
