GPFS cluster creation considerations
A GPFS™ cluster is created using the
mmcrcluster command.
On supported Linux distributions, you can use the installation toolkit to create a GPFS cluster. For more information, see Overview of the installation toolkit.
Table 1 details the cluster creation options, how to change the options, and the default values for each option.
