If installation fails on an NFS-mounted filesystem, ensure that you have write permission on that filesystem. You can check for write permission by following these instructions. For information about installing on an NFS-mounted filesystem, see Installing to an NFS-Mounted File System.
Check for write permission by typing:
touch /net/remote-system/opt/testfile
If you receive an error message, then you do not have write permission. For example:
touch /net/harker/opt/testfile touch: /net/harker/opt/testfile cannot create
Choose another installation directory on which you have write permission, or contact your system administrator to change the filesystem permissions.
