4.5. 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 4.6, “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.
