The file systems can be either of the following:
• External to the node, but internal to the HP XC system. “Mounting Internal File Systems Throughout
the HP XC System” (page 203) describes this situation.
The use of csys is strongly recommended. For more information, see csys(5).
• External to the HP XC system. “Mounting Remote File Systems” (page 207) describes this situation.
NFS mounting is recommended for remote file system mounting.
17.3 Mounting Internal File Systems Throughout the HP XC System
This section describes how to mount a file system on a disk on one node of the HP XC system to other
nodes in the HP XC system using the following example:
Consider an HP XC system whose nodes have the prefix n. A file system is resident on a disk attached to
n60 (this node has the disk_io role); the device name of that file system is /dev/sdb1. The task is to
mount the file system remotely on nodes n61, n62, and n63 at the mount point /scratch.
Figure 17-1 depicts the relationship between the nodes.
