5.4.3.1. Usage
Synchronizing Quota Information
gfs_quota sync -f
MountPoint
MountPoint
Specifies the GFS file system to which the actions apply.
Tuning the Time Between Synchronizations
gfs_tool settune
MountPoint
quota_quantum
Seconds
MountPoint
Specifies the GFS file system to which the actions apply.
Seconds
Specifies the new time period between regular quota-file synchronizations by GFS.
Smaller values may increase contention and slow down performance.
5.4.3.2. Examples
This example synchronizes the quota information from the node it is run on to file system
/gfs
.
gfs_quota sync -f /gfs
This example changes the default time period between regular quota-file updates to one
hour (3600 seconds) for file system
/gfs
on a single node.
gfs_tool settune /gfs quota_quantum 3600
5.4.4. Disabling/Enabling Quota Enforcement
Enforcement of quotas can be disabled for a file system without clearing the limits set for
all users and groups. Enforcement can also be enabled. Disabling and enabling of quota en-
forcement is done by changing a tunable parameter,
quota_enforce
, with the
gfs_tool
command. The
quota_enforce
parameter must be disabled or enabled on each node
where quota enforcement should be disabled/enabled. Each time the file system is mounted,
enforcement is enabled by default. (Disabling is not persistent across unmounts.)
