• Configuring an active/passive Apache HTTP server in a two-node Red Hat Enterprise Linux High Availability Add-On cluster using the pcs command line interface to configure cluster resources

  • Configuring an active/passive Apache HTTP server in a Red Hat High Availability cluster (RHEL 10)
  • Configuring an active/passive Apache HTTP server in a Red Hat High Availability cluster (RHEL 9)

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.
