我有一个软件 raid 0 设置,其中双启动 Windows 7 和 Ubuntu 12.04。硬盘上已有的 GRUB 引导加载程序似乎运行正常。但是,自从 grub 的最新软件包更新以来,它拒绝将新版本安装到硬盘上。grub-install 抛出以下错误:
/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 < [email protected]>
update-grub 弹出相同的
/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。我害怕重新安装 grub 包,因为它可能会搞乱启动,而目前启动工作正常。忽略这个问题安全吗?
编辑:该系统是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:
/dev/mapper/:

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:
