CentOS 8が起動しない：dracutレジュームモードに移行する

CentOS 8をVMWareゲストOSとして実行しています。しばらく使っています。今日、マシンを再起動しましたが、Dracutリソースモードになっています。 OS LVMをアクティブ化することはできません。

このエラーを修正するにはどうすればよいですか？

更新1：

それはDarcutシェルに行きます、私はこれらの2つのコマンドを実行してシェルを終了しなければなりません。

lvm vgscan
lvm vgchange -ay

その後、サーバーが起動します。起動時にLVMがアクティブにならない理由がわかりません。

古いカーネルからの起動にも同じ問題があります。これがrdsosreport行です。

この問題を解決するための2つの考え方。

  1. CentOS 7はcentosをvg名として持っています。CentOS8では、vg名はclです。猫GRUB_CMDLINE_LINUXファイルの/etc/default/grubエントリのvg名を更新する必要があります。
  2. UFIブートの場合、このコマンドを実行する必要がありますgrub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

このコマンドは、ブート引数をgrub2-editenv list表示するのに役立ちました

ありがとう
