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.

Usage
