1.3. Installing GFS2

In addition to the packages required for the Red Hat High Availability Add-On, you must install the gfs2-utils package for GFS2 and the lvm2-cluster package for the Clustered Logical Volume Manager (CLVM). The lvm2-cluster and gfs2-utils packages are part of ResilientStorage channel, which must be enabled before installing the packages.
You can use the following yum install command to install the Red Hat High Availability Add-On software packages:
# yum install lvm2-cluster gfs2-utils
For general information on the Red Hat High Availability Add-On and cluster administration, see the Cluster Administration manual.
