TICKET ARCHIVE -> NFS mounting

msridhar - Dec 26, 2007 - 11:27 pm

I have a RHEL5 NFS server.. The problem is that i cant mount it in my mac os x 10.4... I tried the command mount -t nfs 10.18.1.94:/root/sge-root /root/sge-root... i get the following error..."mount:realpath /root. no such file or directory"..
10.18.1.94 is the address of NFS server... i added the /root/sge-root to the server's export list.. I created the directory sge-root in root in my mac os machine...what might be the problem?

Hi Sridhar -

Thanks for using MacOSX.com! First of all, can you verify that the path on the server is being exported? On your RHEL5 server (as root) issue the following command:

showmount -e

If your /root/sge-root path is not listed you need to export it. Adding it to /etc/exports is the first step, then (again as root on the RHEL5 server:

exportfs -a

Next, make sure that you're specifying a directory on your Mac which exists. For example your mount command as provided requires a directory named /root/sge-root to exist on your Mac.

Finally, Mac OS X will try to use an unprivilaged port for NFS, whereas Linux will expect a privilaged port, so use the "-o -P" options when mounting, like this:

mount -t nfs -o -P 10.18.1.94:/root/sge-root

Let me know how you get on.
