HP XC System Software Administration Guide Version 3.2

Note:
The node that exports the file system to the other nodes in the HP XC system must have the
disk_io role.
3. Determine whether you want to mount this file system over the administration network or
over the system interconnect.
As a general rule, specify the administration network for administrative data and the system
interconnect for application data.
4. Edit the /hptc_cluster/etc/fstab.proto file as follows:
a. Locate the node designator that specifies the node or nodes that will mount the file
system.
Optionally insert a comment regarding why you are changing this file, for example:
# Mount /scratch (from n60) onto n61, n62, and n63
If the node designator does not exist, create it by adding a line similar to this one:
#% n[60-63]
Note:
Be sure to specify the node that exports the file system and the nodes that import the
file system.
b. Enter the fstab information for mounting the file systems, specifying the node that
exports the file system with the hostaddr parameter:
/dev/sdb1 /scratch csys hostaddress=n60,_netdev
c. Save the file.
Example 18-2 (page 222) shows the fstab.proto file after editing for internal file
system mounting.
5. Create the /scratch mount point on each node (including the exporting node) if the mount
point does not already exist:
# cexec -w n[60-63] "mkdir /scratch"
6. Restart the cluster_fstab service on each node:
# cexec -a "service cluster_fstab restart"
