1. Creating a File System
You can create a GFS file system with the
activated LVM volume. The following information is required to execute the
command:
• Lock protocol/module name. The lock protocol for a cluster is
when GFS is acting as a local file system (one node only) is
• Cluster name (when running as part of a cluster configuration).
• Number of journals (one journal required for each node that may be mounting the file
systema.) Make sure to account for additional journals needed for future expansion, as you
cannot add journals dynamically to a GFS file system.
