我正在使用Software Raid 1运行一个服务器，它仅用于使用Idera / R1Soft的备份目的。 最近几天，备份生成非常缓慢，所以我开始怀疑是否有磁盘问题。 不过，我不确定是否是这种情况，所以希望有人能帮助我诊断问题。
下面是大量的磁盘信息，让我知道是否需要其他东西。 这些驱动器看起来是否健康，或似乎是什么问题？ 备份软件保存到/ home /分区，所以这可能是问题所在。
如果其中一个磁盘发生故障，我需要向服务器提供商提供此certificate，我将发送什么？
非常感谢！
问题：mdadm.conf

您的md3数组正在重新同步，这就是为什么它很慢。 根据您的smartctl输出，sda很快就会失败。
