Got a really strange thing happening on my Linux servers.

I have an NTFS file system nfs-automounted on our RedHat servers. Users can read and write to the file system no problem, and can create new files, edit them, and delete them to their heart's content.

The only issue is that utilities such as "dos2unix" cannot create temporary working files:

$ dos2unix events.0818.dat
dos2unix: converting file events.0818.dat to UNIX format ...
Failed to open output temp file: Operation not permitted
dos2unix: problems converting file events.0818.dat

This isn't limited to "dos2unix"; any other utility that creates a temporary working file gets the same problem.

If I copy the file to a local file system like /tmp, it works fine.

Here's the kicker: this works fine on Solaris systems. I can take the "dos2unix" utility over to a Solaris system that has that exact same NTFS file system automounted via NFS, and it works. No issues creating temporary working files at all.

This only happens on my RHEL5 Linux machines. Any idea what could be the cause of this? I'm quite frankly stumped.

Try using the –n switch to create a new file.
Next, you can investigate where the temp files are being written.

Did u ever get a work-around or root cause for this issue ?
Thx
