PowerEdge T410安装ubuntu14.04/14.10错误一则

昨天在一台T410安装ubuntu server安装完起动的时候总提示

Gave up waiting for root device. Common problems:
– Boot args (cat /proc/cdmline)
– 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 v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in (ash)
Enter ‘help’ for a list of builtin commands.

(initramfs)

然后就停在这个命令行了,网上搜索良久,找到解决办法
1.输入exit继续启动系统
2.vi /etc/default/grub
GRUB_CMDLINE_LINUX=”rootdelay=90″
3.update-grub
reboot 发现ok了
