-----Original Message----- From: centos-bounces@centos.org [mailto:centos-bounces@centos.org] On Behalf Of Jason Pyeron Sent: Thursday, November 11, 2010 12:48 To: 'CentOS mailing list' Subject: [CentOS] FW: Permissions issue

I am at loss on this mysterious file permission issue. I cannot move the file out of the directory, but I can rename it. I cannot read the file. It is not open by any processes, the filesystem is in read write mode. I am logged in as root.

More information:

Files can be deleted.

This happens for every file that is created by a tar czf command.

If you do a tar cz | cat > file.tgz the file is "normal"

I am very confused now.
