Clonezillaを使用したLinux Fedoraの複製

実際、私は初めてClonezillaを使用し、私はシステム管理者ではありません。マイコンピュータ（Win7およびFedora22ワークステーション）にあります。

Fedoraは実行されるたびにパーティションサイズのメッセージを表示するので、それを複製してHDサイズを変更し、すべてのパッケージで再インストールする必要があります。これにClonezillaを使用しましたが、実際にClonezillaを起動すると、ClonezillaはWindowsパーティションとマイパーティションデータのみを表示できますが、FedoraのEXT4パーティションは表示されません。

注：また、Clonezillaの代わりに私の要件を達成するための別の簡単な方法があれば良いでしょう。

resize2fsext-xファイルシステムとntfsresizeパーティションのサイズ変更に使用できますntfs。

dd良い選択です左パーティションに10％の空きスペースがあります。

たとえば、折りたたむには/dev/sda1左に移動して展開します/dev/sda2。

  • lsblk：パーティションを識別し、マウント解除されていることを確認してください。
  • fdisk /dev/sdaまたは、パーティションテーブルの種類に応じて、gdisk /dev/sda文字pと：を使用してブロックをq識別します。sector sizealignmentstartend
  • ntfsresize -s (new size) /dev/sda1：/dev/sda1ファイルシステムを縮小します。
  • dd if=/dev/sda2 of=/dev/sda bs=(sector size) seek=(new start)：/dev/sda2ファイルシステムを左に移動します。
  • またはを使用してパーティションを縮小し/dev/sda1、左に移動して展開します/dev/sda2。fdiskgdisk
  • 拡張/dev/sda2ファイルシステムを使用してくださいresize2fs。

計算式は次のとおりnew startです/dev/sda2。 （（/dev/sda1 start sector）* sector size+ new size of /dev/sda1 in bytes→ partition table alignment）/（sector size）

実際のケース（移動およびサイズ変更/dev/sdc1も可能/dev/sdc2）：

Successfully resized NTFS on device '/dev/sdc1'.
You can go on to shrink the device for example with Linux fdisk.
IMPORTANT: When recreating the partition, make sure that you
  1)  create it at the same disk sector (use sector as the unit!)
  2)  create it with the same partition type (usually 7, HPFS/NTFS)
  3)  do not make it smaller than the new NTFS filesystem size
  4)  set the bootable flag for the partition if it existed before
Otherwise you won't be able to access NTFS or can't boot from the disk!
If you make a mistake and don't have a partition table backup then you
can recover the partition table by TestDisk or Parted's rescue mode.
