retaining extended attributes of a file after a copy

info1686 · 01-18-2009, 09:55 PM

Hi all,
I created a file on a Suse 9 x86-64 machine and set some extended attributes for it using setfattr

I then created an archive arc.tar of this file using tar.
Then, I moved the file to another machine, a Suse 10 x86_64 machine using FTP.

However, all extended attributes that were set for the file are lost in the new copy.

Why is this?
Is it conceptually possible to move a file from one machine to another and still manage to retain its extended attributes?

Thanks in advance...

Also both machines have the ReiserFS filesystem

You can try to use star. It's the only program I aware of that preserve extended attributes. Or make something yourself with get/setfattr.
