unable to find device-mapper major/minor? help!!!!! can't boot up! kernel panic!
this is a kinda several part question, from a Linux newbie with a kernel panic issue! Can't boot! Need help...
Linux 2.6.22 When I try to boot, the boot screen freezes at the point of a "kernel panic", and the message just before the kernel panic is "unable to find device-mapper major/minor". What does that mean, and how do I fix it to get the Linux kernel to boot? I tried searching google for this error, and could not find the solution to it. And, is there a way to scroll up the boot message screen to see what other boot messages there are? The screen seems stuck. |
Are you booting via an initramfs (initrd) image or booting the kernel directly into the final filesystem?

OK, what was your older version of kernel?
If you have all the necessary drivers built into the kernel, you can boot without creating the initramfs image - this results in directly mounting the final filesystem without going through a temporary filesystem (initramfs). |

Hi,
Yes, that's your problem. You changed the device so you must create a initrd that reflects that new device. You can use a livecd or install cd to boot the system; After you get to the login then from the cli (command line); Code:
~#mkdir /Your_temp #temporary mount point You should now be able to re-boot your system. BTW, You should be able to pause or view as you go. |
