全新安装 18.04.2 服务器内核空间需要 > 1 小时才能启动

  • 772

我有一个全新安装的 Ubuntu 18.04.2 服务器，需要一个多小时才能启动。我已经研究了一些可能的原因，但还没有找到任何确定的原因。

我在整个磁盘上使用新的 ubiquity 安装程序和guided-lvm。我手动创建了一个交换分区并在安装完成后激活它。我在没有问题的 VM 上尝试了相同的设置，所以我认为这不是这些链接中描述的问题：

systemd-analyze blame 显示：

     18.661s apt-daily.service
     10.376s systemd-udev-settle.service
     10.260s dev-mapper-ubuntu\x2d\x2dvg\x2dsystem\x2d\x2dlv.device
      9.639s cloud-init-local.service
      9.214s snapd.service
      7.875s lxd-containers.service

systemd-analyze 显示：

Startup finished in 1h 2min 5.017s (kernel) + 1min 7.007s (userspace) = 1h 3min 12.024s

POST 后，正常消息飞过，然后每 23 秒我收到一条消息：

Mar  7 15:02:19 server kernel: [   81.401001] floppy: error 10 while reading block 0
Mar  7 15:02:19 server kernel: [  104.223783] print_req_error: I/O error, dev fd0, sector 0

Mar  7 15:02:19 server kernel: [  127.323255] print_req_error: I/O error, dev fd0, sector 0

直到 3725 秒，系统最终挂载文件系统：

Mar  7 15:02:19 server kernel: [ 3723.824233] print_req_error: I/O error, dev fd0, sector 0

Mar  7 15:02:19 server kernel: [ 3725.524789] ip_tables: (C) 2000-2006 Netfilter Core Team

如果有帮助，该机器是 AM3+ GA-78LMT-S2 上的 AMD FX-4100。当我浏览 BIOS 选项时，我没有看到任何禁用软盘控制器的选项。

为什么我没有将软盘驱动程序列入黑名单？好吧，我有点不愿意尝试它，因为运行测试的端到端时间显然是 1 小时。我想我会在这里问一下，看看我是否可以在尝试“将所有内容列入黑名单”方法之前确定根本原因。

    我的设置导致内核搜索软盘驱动器，所以为了排除这种情况，我添加了内核引导参数modprobe.blacklist=floppy，现在系统在大约 1 分钟内引导。

    我通过运行使其永久化：

    echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf

sudo update-initramfs -u

    感谢诊断帮助。
