HP XC System Software Administration Guide Version 3.0

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 administrative 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 hostaddr=n60,_netdev
c. Save the file.
Example 15-2. (page 144) 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"
7. Verify the internal file system mounting by entering the following command, which ensures that the file
system is mounted on the nodes:
# cexec -a "mount | grep /scratch"
n62: 192.168.0.60:/scratch on /scratch type nfs
(rw,hard,intr,bg,rsize=8192,wsize=8192,addr=192.168.0.60)
n61: 192.168.0.60:/scratch on /scratch type nfs
(rw,hard,intr,bg,rsize=8192,wsize=8192,addr=192.168.0.60)
n63: 192.168.0.60:/scratch on /scratch type nfs
(rw,hard,intr,bg,rsize=8192,wsize=8192,addr=192.168.0.60)
n60: /dev/sdb1 on /scratch type ext3 (rw)
Note
The output shown here is edited for clarity. There are actually four lines of output from the command.
