Installation guide

Note

Initializing the quota file requires scanning the entire file system and may take a

long time.

Examples

This example disables quota accounting on file system /gfs on a single node.

gfs_tool settune /gfs quota_account 0

This example enables quota accounting on file system /gfs on a single node and initializes the

quota file.

# gfs_tool settune /gfs quota_account 1

# gfs_quota init -f /gfs

5. Growing a File System

The gfs_grow command is used to expand a GFS file system after the device where the file sys-

tem resides has been expanded. Running a gfs_grow command on an existing GFS file system

fills all spare space between the current end of the file system and the end of the device with a

newly initialized GFS file-system extension. When the fill operation is completed, the resource

index for the file system is updated. All nodes in the cluster can then use the extra storage

space that has been added.

The gfs_grow command must be run on a mounted file system, but only needs to be run on one

node in a cluster. All the other nodes sense that the expansion has occurred and automatically

start using the new space.

To verify that the changes were successful, use the gfs_grow command with the -T (test) and -v

(verbose) flags. Running the command with those flags displays the current state of the moun-

ted GFS file system.

Usage

gfs_grow MountPoint

MountPoint

Specifies the GFS file system to which the actions apply.
