2. Mounting a File System

Before you can mount a GFS file system, the file system must exist (refer to Section 1, “Making

a File System”), the volume where the file system exists must be activated, and the supporting

clustering and locking systems must be started (refer to Chapter 3, Getting Started and Config-

uring and Managing a Red Hat Cluster. After those requirements have been met, you can

mount the GFS file system as you would any Linux file system.

To manipulate file ACLs, you must mount the file system with the -o acl mount option. If a file

system is mounted without the -o acl mount option, users are allowed to view ACLs (with get-

facl), but are not allowed to set them (with setfacl).

Usage

Mounting Without ACL Manipulation

mount -t gfs BlockDevice MountPoint

Mounting With ACL Manipulation

mount -t gfs -o acl BlockDevice MountPoint

-o acl

GFS-specific option to allow manipulating file ACLs.

BlockDevice

Specifies the block device where the GFS file system resides.

MountPoint

Specifies the directory where the GFS file system should be mounted.

Example

In this example, the GFS file system on /dev/vg01/lvol0 is mounted on the /gfs1 directory.

mount -t gfs /dev/vg01/lvol0 /gfs1

Complete Usage

mount -t gfs BlockDevice MountPoint -o option

The -o option argument consists of GFS-specific options (refer to Table 4.2, “GFS-Specific

Mount Options”) or acceptable standard Linux mount -o options, or a combination of both. Mul-

tiple option parameters are separated by a comma and no spaces.
