引导时,出现错误报告,


Gave up waiting for root device. Common problems:


 - Boot args (cat /proc/cmdline)


 - Check rootdelay= (did the system wait long enough?)


 - Check root= (did the system wait for the right device?)


 - Missing modules (cat /proc/modules; ls /dev)


ALERT! /dev/mapper/ubuntu--vg-root does not exist. Dropping to a shell! 



BusyBox v.1.21.1 (Ubuntu 1:1.21.1-1ubuntu1) built-in shell (ash) 


Enter 'help' for list of built-in commands. 



(initramfs)



lsblk输出:


$ lsblk
