Shared File Access
A frequent problem is non-accessible files due to a non-uniform file space. If a task is
run on a remote host where a file it requires cannot be accessed using the same name,
an error results. Almost all interactive LSF commands fail if the user’s current working
directory cannot be found on the remote host.
Shared files on UNIX
If you are running NFS, rearranging the NFS mount table may solve the problem. If
your system is running the
automount server, LSF tries to map the filenames, and in
most cases it succeeds. If shared mounts are used, the mapping may break for those files.
In such cases, specific measures need to be taken to get around it.
The automount maps must be managed through NIS. When LSF tries to map filenames,
it assumes that automounted file systems are mounted under the
/tmp_mnt directory.
Shared files on Microsoft Windows
To share files among Windows machines, set up a share on the server and access it from
the client. You can access files on the share either by specifying a UNC path
(
\\server\share\path) or connecting the share to a local drive name and using a
drive:\path syntax. Using UNC is recommended because drive mappings may be
different across machines, while UNC allows you to unambiguously refer to a file on the
network.
Shared files across UNIX and Windows
For file sharing across UNIX and Windows, you require a third party NFS product on
Windows to export directories from Windows to UNIX.
