3.2. Initial Setup Tasks
Initial GFS2 setup consists of the following tasks:
- Setting up logical volumes.
- Making a GFS2 files system.
- Mounting file systems.
Follow these steps to set up GFS2 initially.
- Using LVM, create a logical volume for each Red Hat GFS2 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 GFS2 file systems on logical volumes created in Step 1. Choose a unique name for each file system. For more information about creating a GFS2 file system, refer to Section 4.1, “Making a File System”.You can use either of the following formats to create a clustered GFS2 file system:
mkfs.gfs2 -p lock_dlm -t
ClusterName:FSName-jNumberJournals BlockDevicemkfs -t gfs2 -p lock_dlm -t
LockTableName-jNumberJournals BlockDeviceYou can use either of the following formats to create a local GFS2 file system:mkfs.gfs2 -p lock_nolock -j
NumberJournals BlockDevicemkfs -t gfs2 -p lock_nolock -j

You can useinit.dscripts included with Red Hat Cluster Suite to automate mounting and unmounting GFS2 file systems. For more information aboutinit.dscripts, refer to Configuring and Managing a Red Hat Cluster.
