RHEL High Availability Documentation: GFS2 File Systems in a Red Hat High Availability Cluster
NOTE: For a general overview of the documentation available for the Red Hat High Availability Add-On, see the Red Hat High Availability Add-On Documentation Guide.
The Red Hat Global File System 2 (GFS2) file system is a 64-bit symmetric cluster file system which provides a shared name space and manages coherency between multiple nodes sharing a common block device. The Red Hat Enterprise Linux (RHEL) Resilient Storage Add-On provides GFS2, and it depends on the RHEL High Availability Add-On to provide the cluster management required by GFS2.
NOTE The Red Hat Enterprise Linux (RHEL) Resilient Storage Add-On will no longer be supported starting with Red Hat Enterprise Linux 10. This includes the GFS2 file system, which is also no longer supported. The RHEL Resilient Storage Add-On will continue to be supported with earlier versions of RHEL (7, 8, 9) and throughout their respective maintenance support lifecycles.
