two parts separated by a colon (no spaces) as
follows:
ClusterName:FSName
.
ClusterName
is the name of the Red Hat cluster for
which the GFS file system is being created. The
cluster name is set in the
/etc/cluster/cluster.conf
file via the Cluster
Configuration Tool and displayed at the Cluster
Status Tool in the Red Hat Cluster Suite cluster
management GUI.
FSName
, the file system name, can be 1 to 16

2. Mounting a File System
Before you can mount a GFS file system, the file system must exist (refer to Section 1,
“Creating 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 2, Getting Started
and Configuring 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
getfacl
), but are not allowed to set them (with
setfacl
).
Usage
Mounting Without ACL Manipulation
mount BlockDevice MountPoint
Mounting With ACL Manipulation
mount -o acl BlockDevice MountPoint
