In this example, the NFS server process is not listed in the registered programs
on NAS Gateway 500. So we know the NFS server on NAS Gateway 500 is not
up and running. If you get this problem, please review the NAS Gateway 500
setup process, and make sure there is no error reported during the NFS share
The reverse lookup problem on Red Hat Linux
Sometimes you may get the error message shown in Example 13-9 while
mounting a NAS Gateway 500 NFS share on Red Hat Linux.
Example 13-9 Red Hat NFS mounting error 3
[root@naslinux root]# mount -t nfs /mnt/nfs
mount: failed, reason given by server: unknown nfs
status return value: -1
This is usually caused by the reverse lookup problem, which means NAS
Gateway 500 can’t resolve the IP address of the Red Hat Linux client to host
You must configure name resolution on NAS Gateway 500 to fix this problem.
See “The reverse lookup problem on AIX” on page 366 for the detailed steps.
13.2 SUSE LINUX: Access a NAS Gateway 500 share
Here we explain how to access a NAS Gateway 500 NFS share from SUSE
LINUX. We also provide some troubleshooting information for integrating NAS
Gateway 500 with SUSE LINUX.

13.2.1 Mounting a NAS Gateway 500 NFS share on SUSE LINUX
Here we discuss the mount command used to mount a NAS Gateway 500 NFS
share on SUSE LINUX, and how to make the NFS share mounted automatically
at system startup.
The mount command to use on SUSE LINUX
In order to mount a NAS Gateway 500 NFS share on SUSE LINUX, the mount
command should be used as shown in Example 13-10.
Example 13-10 NFS mount command on SUSE
naslinux:~ # mount -t nfs /mnt/nfs
The -t option of the mount command on SUSE LINUX indicates the filesystem
type to be mounted. It should always be nfs while mounting a NAS Gateway 500
NFS share. You can also combine other mounting options with the mount
command. See the SUSE LINUX documents for a detailed description of
mounting options.
After the mount command is returned, you can run the mount command without
parameters to verify the mount status (Example 13-11).
Example 13-11 SUSE: the mount command output
naslinux:~ # mount
/dev/hda2 on / type reiserfs (rw)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
shmfs on /dev/shm type shm (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw) on /mnt/nfs type nfs (rw,addr=
The NFS share, mount point, filesystem type, and mount options are displayed
with this command.
Mount the NAS share automatically at system startup
In order to mount the NFS share automatically at SUSE LINUX startup, we can
either configure the NFS client in yast2, or edit the /etc/fstab file on SUSE LINUX.
The configuration of the NFS client with yast2 is very straightforward, and yast2
accomplishes this task by modifying the /etc/fstab file. The /etc/fstab file on
SUSE LINUX contains descriptive information about filesystem. It is processed
by the system scripts of SUSE LINUX during system startup. Our /etc/fstab is
shown in Example 13-12. See the SUSE LINUX documentation for a detailed
description of the /etc/fstab file.
