3. Unmounting a File System
The GFS file system can be unmounted the same way as any Linux file system — by using the
umount
command.
Note
The
umount
command is a Linux system command. Information about this
command can be found in the Linux
umount
command man pages.
Usage
umount MountPoint
MountPoint
Specifies the directory where the GFS file system should be mounted.
4. Displaying GFS Tunable Parameters
There are a variety of parameters associated with a GFS file system that you can modify with
the
gfs_tool settune
command. Some of these parameters are used to administer GFS
quotas:
quota_quantum
,
quota_enforce
,
quota_account
, and
atime_quantum
. These
parameters are described in Section 5, “GFS Quota Management” , along with examples of how
to modify them.
Parameters that you set with the
gfs_tool settune
command must be set on each node each
time the file system is mounted. These parameters are not persistent across mounts.
Note
The majority of the tunable parameters are internal parameters. They are
intended for development purposes only and should not be changed.
The
gfs_tool gettune
command displays a listing of the current values of the GFS tunable
parameters.
