软突袭 1 慢（磁盘故障？）

  • 772

我正在运行带有 Software Raid 1 的服务器，它仅用于使用 Idera/R1Soft 进行备份。最近几天，备份生成非常缓慢，所以我开始怀疑是否存在磁盘问题。但是我不确定是否是这种情况，所以希望有人可以帮助我诊断这个问题。

以下是磁盘的大量信息，如果需要其他信息，请告诉我。这些驱动器看起来是否健康，或者似乎是什么问题？备份软件保存到 /home/ 分区，所以这可能是问题所在。

如果其中一个磁盘出现故障，我需要向服务器提供商发送证明，我应该发送什么？

非常感谢！

    您的 md3 数组正在重新同步，这就是它很慢的原因。根据您的 smartctl 输出，sda 很快就会失败。

    查看所有 Pre-fail 类型？如果我是你，我会尽快更换磁盘。
