Question 10: You are troubleshooting the failure of a computer to mount an NFS file system hosted by a
server (hostname mars) in the local area network.
Select the three commands that will enable you to identify the problem.
A. ping - s mars
B. cat /etc/vfstab
C. cat /etc/dfs/dfstab
D. sharemgr show -v
E. showmount -e mars
F. rpcinfo -s mars | egrep 'nfs|mountd'
Correct Answer: A,E,F
Explanation:
mount: mount-point /DS9 does not exist.
To solve the mount point error condition, check that the mount point exists on the client.
Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on
the client, or comment outthe entry and reboot the system.
Note: The /etc/vfstab file lists all the file systems to be automatically mounted at system
boot time, with the exception of the /etc/mnttab and /var/run file systems.
E: showmount This command displays all clients that have remotely mounted file systems that are
shared from an NFS server, or only the file systems that are mounted by clients, or the shared file
systems with the client access information. The command syntax is:
showmount [ -ade ] [ hostname ]
where -a prints a list of all the remote mounts (each entry includes the client name and the
directory), -d prints a list of the directories that are remotely mounted by clients, -e prints a list of the
files shared (or exported), and hostname selects the NFS server to gather the information from. If
hostname is not specified the local host is queried.
F: * mountd Daemon
This daemon handles file-system mount requests from remote systems and provides
access control. The mountd daemon checks /etc/dfs/sharetab to determine which file
systems are available for remote mounting and which systems are allowed to do the
remote mounting.
* Commands for Troubleshooting NFS Problems
These commands can be useful when troubleshooting NFS problems.
rpcinfo Command
This command generates information about the RPC service that is running on a system.
