setfattr operation not supported

$ touch foobar$ setfattr -n user.foo -v bar foobarsetfattr: foobar: Operation not supported

The file as all permission, same for folder. What could be the issue here? It's Ubuntu 9.10

This is in my fstab

/dev/sdb1 /var/log/apache_logs          reiserfs    user,noauto,rw,exec,suid,user_xattr 

(I'm working somewhere in those dir but I've tried elsewhere too and it's the same)
