HP XC System Software Administration Guide Version 2.1
xeno:/extra /workarea nfs rw,_netdev
This means that the node with this fstab file entry mounts the file system name d /extra,
which is exported from the system n amed xeno, and mounts it at /workarea. The file
system can be read from and written to. The _netdev optio n means that the file system is not
mounted unt il th e n etwork is up.
14.4.2 Mounting Remote File Systems
Use the following procedure to m oun t a remote file system to one or more nodes in an HP
XC system :
1. Determine which file system should be exported.
In this example, the file system /extra is exported by the external server xeno.
2. Ensure that this file system can be NFS exported.
_______________________ Note _______________________
This information is system dependent and is not covered in this manual.
Consult the d ocum e ntatio n for the external server.
3. Log in as superuser on the head node.
4. Ensure that the mount point directory ex ists on all the nodes that will mount the rem ote
file system.
If the mount point directory does not exist, you need to create it on each node, as shown
here:
# cexec -w n[22-24] /bin/mkdir /workarea
_______________________ Note _______________________
This mount point will exist u ntil the n ode is reimaged.
5. Edit the /hptc_cluster/etc/fstab.proto file as follows:
a. Locate the node designator (if it a lready exists) that specifies the node or nodes
that will im port the file system.
Optionally insert a comment regarding why you are changing this file.
#Mount /extra (from xeno) onto /workarea on nodes n[22-24]
If the node designator does not exist, create it by adding a line simil ar to this one. F or
this example, the n ode designator is as follows :
#% n[22-24]
b. Enter the fstab inf or m at ion for mounting the file system. The mounting
instructions for this example are:
xeno:/extra /workarea nfs rw,_netdev
c. Save the file.
Example 1 4-3 show s the fstab.proto file after editing for remote mounting.
6. Restart the cluster_fstab service on each node that w ill mount t he remote file system:
# cexec -w n22,n23,n24 service cluster_fstab restart
7. Verify that the remote file system is mounted b y entering the following command:
# cexec -a mount | grep mountpoint
