Permission denied. Mounting a remote /cdrom

[Rob Wallner]

I am trying to mount a cdrom on another server. I have done this hundreds of times without fail Now i am getting an error permmision denied.

Server number 1 (With the CDROM)
/etc/exports
/cdrom -anon=65534,ro,root=msc00

when I do a export /cdrom
sh: /cdrom: This is not an identifier.
export cdrom seems to work.

But when I go to server 2 to and do a
root@msc00-> mount -F nfs server1:/cdrom /cdrom
I get Permission denied
I am not sure what is happening.

You are confusing the "exportfs" command with the shell built-in "export".

"export cdrom" says export the variable "cdrom" so that it is available to all child processes.

Hi,

To make the export permanent, add a line to /etc/exports, and run 'exportfs -a'.

HI:

The ommand 'export' is a shell command to export a variable into your environment.

The message "...is not an identifier" when you specify "/cdrom" is because a valid identified can't begin with a slash. When you dropped the slash and did "export cdrom" you did'nt get any error simply because the command *was* valid. You exported an empty variable named "cdrom" into your shell environment!

Regards!

Hi Rob,

To be certain the filesystem is exported correctly I'd recommend the following:

On the server: cat /etc/xtab
On the client: showmount -e

The /etc/xtab file contains a copy of what the server's kernel believes are the exported filesystems, regardless of what is in the /etc/exports file or what exportfs command was issued.

The showmount -e command on the client will not only verify that the server has exported filesystems but that the client is able to communicate with the server's rpc.mountd daemon to get the list of exported filesystems remotely.

If both of these commands show the /cdrom filesystem is exported properly and the mount is still not working then I can give you a set of steps to collect more data to identify the underlying problem.

Regards,

Dave

Hi,

Remove the /cdrom directory on client and recreate and mount it again.It will work
