mount can get its parameters explicitly from the command line or from /etc/vfstab. The examples below assume command line arguments, but the same debugging techniques work if mounting is done automatically through /etc/vfstab.
mount: ... server not responding: RPC:Program not registered
Either the server sharing the resource you are trying to mount is down,
or is at the wrong init state, or its rpcbind is dead or hung, or
mount got through to rpcbind, but the NFS mount
daemon mountd
is not registered. You can check the server's init state by entering (at
the server) the following command:
who -r
If the server is at init state 3, try going to another init state and back, or try rebooting the server to restart rpcbind. Try to log in to the server from your machine, using the rlogin command. If you can't log in, but the server is up, try to log in to another remote machine to check your network connection. If that connection is working, check the server's network connection. See who(C) for more information on the who command. If mountd is not running, try restarting NFS. See ``Starting and stopping NFS'' for information on restarting NFS.
mount: ... : No such file or directory
Either the remote directory or the local directory does not exist. Check the spelling of the directory names. Use ls on both directories.
mount: ... : Permission denied
This message indicates that the user does not have the appropriate permissions or that some authentication failed on the server.
mount: ... : Not a directory
The local path is not a directory. Check the spelling in your command, and run ls to check if local path is a directory or not.
mount: mount-point does not exist
The local directory where the resource in being mounted (mount-point) does not exist.
nfs mount: access denied for host:path
It may be that you are not in the share list or that the filesystem
you want is not shared by the server. You can display the server's share
list by entering the following:
dfshares -F nfs server
Check the server's /etc/xtab file.
nfs mount: nfs filesystem; use host:path
The command entered has a syntax error. The resource specified has to be of the form host:path.
