3.2. Initial Setup Tasks
Initial GFS setup consists of the following tasks:
- Setting up logical volumes
- Making a GFS files system
- Mounting file systems
Follow these steps to set up GFS initially.
- Using LVM, create a logical volume for each Red Hat GFS file system.
Note
You can useinit.dscripts included with Red Hat Cluster Suite to automate activating and deactivating logical volumes. For more information aboutinit.dscripts, refer to Configuring and Managing a Red Hat Cluster. - Create GFS file systems on logical volumes created in Step 1. Choose a unique name for each file system. For more information about creating a GFS file system, refer to Section 4.1, “Creating a File System”.You can use either of the following formats to create a clustered GFS file system:
gfs_mkfs -p lock_dlm -t
ClusterName:FSName-jNumberJournals BlockDevicemkfs -t gfs -p lock_dlm -t
LockTableName-jNumberJournals BlockDeviceYou can use either of the following formats to create a local GFS file system:gfs_mkfs -p lock_nolock -j
NumberJournals BlockDevicemkfs -t gfs -p lock_nolock -j

You can useinit.dscripts included with Red Hat Cluster Suite to automate mounting and unmounting GFS file systems. For more information aboutinit.dscripts, refer to Configuring and Managing a Red Hat Cluster.
