如何强制（或解决）logrotate将旧日志移动到不同物理磁盘上的olddir？

I want logrotate to copy and truncate log file and use olddir on different physical disk. According to manual, olddir can't be on different physical disk because default behaviour of logrotate is to only rename original log file, which wouldn't be possible with different physical disk. to copy and truncate log file
