我使用的是 Neoseries T24 (Flexstor II) 自动加载器,带有两个驱动器。我的磁带 (11 盘) 位于标记为“已满”的池中。
当我运行两个针对“完整”池的作业时,它们将按顺序等待,以便它们都可以使用同一个驱动器(0),而不是一个在驱动器 0 上运行,一个在驱动器 1 上运行。
这是因为我在标签过程中选择了驱动器 0 吗?
是否可以将全池中的任何磁带放入自动加载机中的可用驱动器中,以便同时运行两个作业?
是否需要运行两个 SD 守护进程?

答案1
默认情况下,Bareos 作业将优先写入已安装的卷。如果您有多个驱动器自动转换器,并且希望 Bareos 同时写入同一池中的多个卷,则需要设置首选已安装卷目录作业 = 否。这将导致存储守护进程最大限度地利用驱动器。
