Доброго времени суток.
Суть проблемы вот в чем:
необходимо, чтобы команда(именно так - и источник, и приемник указаны как remote) отрабатывала без единой ошибки:
scp root@10.1.0.1:/backup/1112.tar root@10.1.0.1:/usr/shara02/111.tar
На данный момент ошибка
scp:  truncate: Invalid argument  (при этом, файл на шару копируется, успешно открывается и т.д.)

есть сервер(ASPLinux Server V) - 10.1.0.1. Монтирую расшаренный ресурс NAS(10.1.0.2) в папку : /usr/shara02
строка в fstab
\\10.1.0.2\public  /usr/shara02  cifs root password=pass, uid=0, gid=501, username=root, 0  0
Серв 10.1.0.1 ходит сам на себя по ssh с использованием ключа rsa.
Команда
rsync /backup/1112.tar root@10.1.0.1:/usr/shara02/111.tar отрабатывает нормально,
как и
cp /backup/1112.tar /usr/shara02/111.tar.
Также без ошибок отрабатывает в обратную сторону:
scp  root@10.1.0.1:/usr/shara02/111.tar root@10.1.0.1:/backup/1112.tar
На другом серваке(аналогичные конфиги ssh, аналогичная строка монтирования шары в fstab) также ошибок нет.
На всякий случай
[root@servername ~]# scp -v  root@10.1.0.1:/backup/1112.tar root@10.1.0.1:/usr/shara02/111.tar
Executing: /usr/bin/ssh -v -x -oClearAllForwardings yes -t -l root 10.1.0.1 scp -v /backup/1112.tar root@10.1.0.1:/usr/shara02/111.tar
