grub拒绝安装到RAID阵列

我有双重启动Windows 7和Ubuntu 12.04的软件RAID 0设置。硬盘驱动器上已有的GRUB引导加载程序似乎可以正常工作。但是，由于grub的最新软件包更新，它拒绝将新版本安装到硬盘上。grub-install引发以下错误：

/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name>_RAID0p9. Check your device.map.
Auto-detection of a filesystem of /dev/mapper/< raid name>_RAID0p9 failed.
Try with --recheck.
If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to < bug-grub@gnu.org>

update-grub弹出相同

/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/< raid name>_RAID0p9. Check your device.map.

每隔一行。

我不明白到底发生了什么。恐怕要重新安装grub软件包，因为它可能会使启动混乱，目前可以正常使用。忽略这一点是否安全？

编辑：系统是Alienware M17xR4，我不知道如何更好地描述主板。

编辑2：这是“ ls -alFR / dev / mapper /”的输出：

默认情况下，/ boot / grub / device.map不存在。这是通过“ / usr / sbin / grub-mkdevicemap”创建后的内容：
