1 Six GB of swap space is subtracted from the total disk space, and space for all other file systems is calculated from
the remaining disk space.
2 4 GB might be too small for some hardware configurations. See Section 2.1.5 (page 38) for more information about
determining how large this partition must be.
The HP XC System Software Administration Guide describes the purpose and content of each file
system.
The default disk partition layout for all other nodes in the cluster (that is, nodes other than the
head node) is listed in Table 5-4 (page 90).
2.1.5 4 GB /hptc_cluster Partition Size Limit Might Be Too Small for Some Hardware
Configurations
The maximum size of the /hptc_cluster partition created during the Kickstart installation is
4 GB, however, 4 GB might be too small for some hardware configurations. As listed in Table 2-4,
the number of nodes in the hardware configuration and whether or not you are configuring
improved availability of services determines if 4 GB is acceptable or is too small.

Based on the hardware and system configuration, if the data in Table 2-4 indicates that 4 GB is
too small for the /hptc_cluster partition, use the guidelines in the following sections to create
the appropriate sized partition. The guidelines depend on whether /hptc_cluster is located
on an HP Scalable File Share (SFS) server or is created on the local system disk.

• “Determining the Size of /hptc_cluster When It Is Located on a Local Disk on the Head
Node”
