/**************************************************************************/ [bugs #10333] Full Item Snapshot: URL: <http://savannah.gnu.org/bugs/?func=detailitem&item_id=10333> Project: GNU GRUB Submitted by: 0 On: Thu 09/09/2004 at 12:46 Category: Filesystem Severity: Major Priority: 5 - Normal Item Group: None Resolution: None Privacy: Public Assigned to: None Originator Name: Tom Bryan Originator Email: Status: Open Release: 0.93 Reproducibility: Every Time Planned Release: Summary: grub seeing wrong kernel image version number after partition copy Original Submission: On a Red Hat 9.0 GNU/Linux system, I'm running grub 0.93. /boot is on the same partition as the root partition. My original root partition was the ext3 partition (hd0,7), and I can still boot that configuration without a problem. I want to move my root partition to (hd1,0). I used fdisk to partition and format (hd1,0) as ext3. To copy the data from (hd0,7) to (hd1,0), I booted a Knoppix CD, mounted the drives at /mnt/old and /mnt/new, and ran cp -avx /mnt/old/* /mnt/new/ grub.conf now looks like this on both partitions (at /boot/grub/grub.conf): default=0 timeout=10 splashimage=(hd1,0)/boot/grub/splash.xpm.gz title Red Hat Linux (2.4.20-8) root (hd0,7) kernel /boot/vmlinuz-2.4.20-8 ro root=/dev/hda8 initrd /boot/initrd-2.4.20-8.img title Red Hat Linux (2.4.20-8 new hard drive) root (hd1,0) kernel /boot/vmlinuz-2.4.20-8 ro root=/dev/hdb1 initrd /boot/initrd-2.4.20-8.img If I boot using the original partition (hd0,7), then I can mount (hd1,0) at, for example, /newroot. Then I can see /newroot/boot/vmlinuz-2.4.20-8. I mounted (hd1,0) this way and ran rdev to switch the kernel's root device to /dev/hdb1. Now, I reboot. If I select the original configuration, the system boots fine. If I select the new, (hd1,0) configuration, grub stops with error 15 : File not found, indicating that it cannot find /boot/vmlinuz-2.4.20-8. I rebooted and dropped to the grub command prompt. If I type kernel (hd1,0)/boot/vmlinuz- and press tab, grub tab-completes to kernel (hd1,0)/boot/vmlinuz-2.4.18-3. If I tab-complete at (hd1,0)/boot/, then all of the files that show as 2.4.20-8 when the partition is mounted (under Knoppix, for example) show up as 2.4.18-3. I then tried modifying the config file so that the second configuration read title Red Hat Linux (2.4.18-3 new hard drive) root (hd1,0) kernel /boot/vmlinuz-2.4.18-3 ro root=/dev/hdb1 initrd /boot/initrd-2.4.18-3.img When I save that to grub.conf and reboot, I can select the new hard drive configuration. Grub boot and apparently finds the kernel file. Of course, then the system has other problems because I have no /lib/modules-2.4.18-3, for example. (It boots to a login prompt, but not all of my modules are loaded correctly.) My big question is how does grub determine the filename? I just don't even know what to look at next. Why is grub seeing a different filename from the one reported by the OS when I mount the partition under GNU/Linux?
