Thanks Jim. Unfortunately I get the following error when trying to create a hard link:
Invalid cross-device link

Thanks also but the find cmd doesn't have a -L or a -H and I can't change the cmd in this instance so I need a work around with the link creation. Although none may be possible.

Yes it's just a normal ln -s link from a dir on one file system to that on another on the same host. A find cmd won't list any file under that link without an additional param like -L. Would just like to know if I can change the link in some way (rather than the find cmd) to get this to work. Thanks.

symlink
SYMLINK(2) Linux Programmer's Manual SYMLINK(2)
NAME
symlink - make a new name for a file
SYNOPSIS
#include <unistd.h>
int symlink(const char *oldpath, const char *newpath);
DESCRIPTION
symlink creates a symbolic link named newpath which contains the string oldpath.
Symbolic links are interpreted at run-time as if the contents of the link had been substituted into the path being followed to find a file
or directory.
Symbolic links may contain .. path components, which (if used at the start of the link) refer to the parent directories of that in which
the link resides.
A symbolic link (also known as a soft link) may point to an existing file or to a nonexistent one; the latter case is known as a dangling
link.
The permissions of a symbolic link are irrelevant; the ownership is ignored when following the link, but is checked when removal or renam-
ing of the link is requested and the link is in a directory with the sticky bit set.
If newpath exists it will not be overwritten.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
ERRORS
EPERM The filesystem containing newpath does not support the creation of symbolic links.
EFAULT oldpath or newpath points outside your accessible address space.
EACCES Write access to the directory containing newpath is not allowed for the process's effective uid, or one of the directories in new-
path did not allow search (execute) permission.
ENAMETOOLONG
oldpath or newpath was too long.
ENOENT A directory component in newpath does not exist or is a dangling symbolic link, or oldpath is the empty string.
ENOTDIR
A component used as a directory in newpath is not, in fact, a directory.
ENOMEM Insufficient kernel memory was available.
EROFS newpath is on a read-only filesystem.
EEXIST newpath already exists.
ELOOP Too many symbolic links were encountered in resolving newpath.
ENOSPC The device containing the file has no room for the new directory entry.
EIO An I/O error occurred.
NOTES
No checking of oldpath is done.
Deleting the name referred to by a symlink will actually delete the file (unless it also has other hard links). If this behaviour is not
desired, use link.
