我已成功增加 AWS EBS 卷上的空间。

# lsblk
NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
nvme0n1      259:0    0   64G  0 disk 
├─nvme0n1p1  259:1    0 63.9G  0 part /

└─main-var   254:0    0  996G  0 lvm  /var

如何将 1T 添加到 1Tnvme1n1上main-var lvm？

我已经使用 Check_MK 版本 1.5.0p13 配置了 AWS 监控（遵循 Check_MK 官方站点上的文档）。一切正常，除了 RDS 检查，当我去发现服务时，我得到：

Service discovery failed for this host: 'DBName'

我可以做些什么来调试这个问题，我在哪里可以获得更多输出？任何想法如何解决这个问题？

这是输出：

cmk -vI aws

我正在我们的 AWS 账户上测试 GuardDuty 并且有一些问题...

我们管理的每个 EC2 实例都有一个“Recon:EC2/PortProbeUnprotectedPort”结果。每个用于不同的端口：

  • EC2 实例 1：1433
  • EC2 实例 2：433
  • EC2 实例 3：9000
  • EC2 实例 4：554
  • EC2 实例 5：110

所有实例都在 Debian 上，nmap 扫描实例 5：

Not shown: 993 closed ports
PORT     STATE    SERVICE
21/tcp   open     ftp
22/tcp   open     ssh
80/tcp   open     http
443/tcp  open     https
445/tcp  filtered microsoft-ds
8086/tcp open     d-s-n
8088/tcp open     radan-http

实例上的 Netstat 输出：

没有迹象表明端口 110 已打开。

对这个问题有任何合理的解释吗？

我有 Infortrend DS S16E-G2152-6 NAS，RAID 6 中的 16 个 4TB 驱动器 (WD4000FYYZ)。上周一个驱动器出现故障，已更换并正在重建。在大约 80% 的重建过程中，另外两个驱动器同时发生故障。

控制器重置正在唤醒故障驱动器之一，但恢复再次失败。

现在，其中一个故障驱动器将被专业地克隆到非常相似的新驱动器上。我希望我可以将它粘贴在阵列中，NAS 会认为它是可以工作的旧驱动器并开始重建（我假设它只会看到 1 个故障驱动器和一个干净的驱动器）。

我的假设正确吗？NAS 是否检查驱动器上的文件系统和数据，以了解它是来自设备还是序列号和固件？还是别的什么？

谢谢
