論理ボリュームのルートファイルシステムを別のディスクに移動する

論理ボリュームのルートファイルシステムを別のディスクに移動する

私のルートLVを新しいSSDの新しいVGに移動しようとしていますが、本当に狂っているようです。私はrsyncを使ってこれを達成したと思いましたが、今grubは/ dev / vg_ssd / lv_rootで新しい起動オプションの登録を拒否します。 LinuxにAIXのようにcplvやlvmoveがないのはなぜですか?

vg_dopey/lv00の代わりにvg_ssd/rootを使って/にマウントしたいと思います。 /bootは独立です。グラップ2/FC17。 Linux dopey 3.6.2-4.fc17.x86_64 #1 SMP Wed Oct 17 02:43:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

答え1

pvmoveVG内のLVを既存のPVから別のPVに移動します。

これにより問題が解決する可能性があります。

答え2

fstabが破損しているようです。修正して、/etc/fstabインストールルートの行を新しい行(おそらくUUID = XXX)に変更します。

すべてのuuidを見つけるには、blkidrootとして実行します。

grub.cfgが古い場合は、grub-mkconfig -o /boot/grub/grub.cfggrub.cfgの再生成を使用してください。

編集する

grubがルートデバイスを検索すると、現在インストールされているデバイスがルートデバイスと見なされます。 grub.cfgを手動で修正し、SSDから起動してgrub-mkconfig再実行する必要があります。
