92 Chapter 9. Managing GFS
Chapter 4 Initial Configuration ). 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 sys-
tem 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
).
9.2.1. 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.
9.2.2. Example
In this example, the GFS file system on the
pool0
block device is mounted on the
/gfs1/
directory.
mount -t gfs /dev/pool/pool0 /gfs1
9.2.3. Complete Usage
mount -t gfs BlockDevice MountPoint -o option
The
-o
option
consists of GFS-specific options (refer to Table 9-2) or acceptable standard Linux
mount -o
options, or a combination of both. Multiple
option
parameters are separated by a comma
and no spaces.
Note
The
mount
command is a Linux system command. In addition to using GFS-specific options de-
scribed in this section, you can use other, standard,
mount
command options (for example,
-r
). For
information about other Linux
mount
command options, see the Linux
mount
man page.
Table 9-2 describes the available GFS-specific options that can be passed to GFS at mount time.
