恢复 Ubuntu Server 16.04 后出现错误。它仅启动提前恢复选项 (initramfs)。以下是完整错误。有人可以帮忙吗？
Begin: Running /scripts/local-block...mdadm: CREATE group disk not found

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/DDNSRV--vg-root does not exist. Dropping to a shell!
