我试图在 Ubuntu 服务器上安装一个 10Tb 磁盘。由于磁盘容量很大，我不得不使用分开代替磁盘管理。遗憾的是，我没有启用GPT 支持在安装磁盘之前，在 Linux 内核中。重新启动服务器后，它无法启动。我最初的想法是，这是 grub 的问题，所以我尝试在 上重新安装 grub2：
[*] /dev/sda
[*] /dev/sdb
使用以下命令：
apt-get install --reinstall grub-pc
dpkg-reconfigure grub-pc
但后来我在网上发现：
如果您没有在 Linux 内核中添加 GPT 支持，则重新启动服务器后，文件系统将不再可挂载，或者 GPT 表将损坏。
我能够使用主机提供商提供的救援服务访问系统。这是一个基于 Debian 的 Linux 系统。以下是我从救援 Linux 服务获得的 df -h 和 fdisk -l 命令的输出：

我该如何解决这个问题？
服务器：ubuntu-16.04.6-server

答案1
/etc/fstab通过删除原始系统（非救援系统）的 10TB 文件系统文件中的原始条目来解决。
对于将来访问此问题的任何人来说：使用 Ubuntu 可启动 USB 棒或恢复环境并：
- 挂载原始启动驱动器的文件系统
- 使用文本编辑器删除导致问题的分区/驱动器的条目
/etc/fstab。
一旦删除该条目，机器就可以启动。
