2. 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 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 -j Number BlockDevice

mkfs -t gfs -p lock_dlm -t LockTableName -j NumberJournals BlockDevice

You can use either of the following formats to create a local GFS file system:

gfs_mkfs -p lock_nolock -j NumberJournals BlockDevice

mkfs -t gfs -p lock_nolock -j NumberJournals BlockDevice

For more information on creating a GFS file system, see Section 1, “Creating a File System”.

3. At each node, mount the GFS file systems. For more information about mounting a GFS file

system, see Section 2, “Mounting a File System”.

Command usage:

mount BlockDevice MountPoint

mount -o acl BlockDevice MountPoint

The -o aclmount option allows manipulating file ACLs. If a file system is mounted without

the -o acl mount option, users are allowed to view ACLs (with getfacl), but are not allowed

to set them (with setfacl).

Note

You can use init.d scripts included with Red Hat Cluster Suite to automate

mounting and unmounting GFS file systems. For more information about init.d

scripts, refer to Configuring and Managing a Red Hat Cluster.
