重启系统按 e 删除加载 swep 分区的代码，然后按 ctrl+x 启动：

                               GRUB version 2.06

      Minimum Emacs-like screen editing is supported. TAB lists           
      completions. Press Ctrl-x or F10 to boot, Ctrl-c or F2 for          
      a command-line or ESC to discard edits and return to the GRUB menu.
Bash

启动系统后编辑 GRUB 配置：

sudo vim /etc/default/grub

# 修改 GRUB_CMDLINE_LINUX 参数
GRUB_CMDLINE_LINUX="resume=/dev/mapper/rl_anonymous-swap rd.lvm.lv=rl_anonymous/root rd.lvm.lv=rl_anonymous/swap console=ttyS0"
# 修改为
GRUB_CMDLINE_LINUX="rd.lvm.lv=rl_anonymous/root console=ttyS0"
Bash

更新 GRUB 配置：

# 对于 BIOS 系统：
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

# 对于 UEFI 系统：
sudo grub2-mkconfig -o /boot/efi/EFI/rocky/grub.cfg
# 或者根据您的发行版：
sudo grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Bash

重新生成 initramfs：

sudo dracut -f --regenerate-all
Bash

重启顺利进入系统。

如果还是无法启动检查 /boot/loader/entries 下的文件：

[root@k8s-node-02 ~]# cat /boot/loader/entries/*.conf

更新所有 BLS 配置文件：

sed -i 's/resume=\/dev\/mapper\/rl_anonymous-swap//g' /boot/loader/entries/*.conf
sed -i 's/rd.lvm.lv=rl_anonymous\/swap//g' /boot/loader/entries/*.conf
sed -i 's/  / /g' /boot/loader/entries/*.conf  # 清理多余空格
Bash
