redhat 備份虛擬機還原開機後出現錯誤 fsck.ext3: memory allocation failed while retrying to read bitmaps for /p1

 一台redhat 備份虛擬機，在還原到其他硬體，開機後出現錯誤

fsck.ext3: memory allocation failed while retrying to read bitmaps for /p1 

an error occurred during the file system check dropping you to a shell the system will reboot when you leave the shell

這時就先去查/p1是掛在哪個硬碟後，用root密碼登入，執行下列指令

fsck -y /dev/sda1

完成後在執行 reboot，就可以正常進入到系統了。
