Kernel Panic! Calm down
Hi,
Today I felt bolder than yesterday, and thus decided to attempt a "harddrive swap". I bought a new harddisk couple of weeks ago and hooked it up as slave until I'll have time to migrate my linux partitions. That day had come. However I failed again. Here's what happened. I first booted using the Redhat CD in rescue mode and copied everything on a new partition (created using partitionmagic) with the command cp -pR. I then changed the IDE cables as to make the new disk primary master. Then I powered the pc and booted again using the rescue cd. I invoked grub and did the following: root (hd0,1) setup (hd0) I also tweaked the grub.conf file since the partition numbering had changed (the boot used to be (hd0,0)). Finally I crossed my fingers and rebooted. Naturally it didn't work. Here is the exact error messaging during boot-up. Mounting root filesystem VFS: Can't find ext3 filesystem on dev ide0(3,6). mount: error 22 mounting ext 3 pivotroot: pivot_root(/sysroot,/sysroot/initrd) failed:2 umount /initrd/proc failed:2 Freeing unused kernel memory: 128k freed Kernel panic: No init found. Try passing init= option to kernel Now I have checked the grub.conf file for further changes but couldn't find any (I appended it to this message) Do you know how I shoud proceed? I couldn't understand the line root=LABEL=/ Anaconda says it should be root=/dev/hda6 However it boots correctly in my current system. Is that the part I have to change? Thanks in advance, Bibby # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/hda6 (root is not hda6 anymore, it is hda3) # initrd /initrd-version.img #boot=/dev/hda default=0 timeout=5 splashimage=(hd0,1)/grub/tigutz.xpm.gz title Red Hat Linux 9 root (hd0,1) kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdd=ide-scsi apm=off acpi=off initrd /initrd-2.4.20-8.img title Windows rootnoverify (hd0,1) chainloader +1 |
RH uses partiton labels in the fstab instead of /dev/. You didn't create labels on the new drive so it can't find anything.
To create partition labels use label2fs. |

Swap cables again and boot with the RH rescue cd. mount the partition and chroot to it. invoke the command label2fs. How does that work? Do I specify a label along with a drive such as label2fs / /dev/hda3 I am asking all these questions since I won't have the opportunity to connect to the internet during the process, and I have to know precisely what I'll have to do.

Here is the correct utility http://www.die.net/doc/linux/man/man8/e2label.8.html mounting and chroot will probably not work because your fstab file still references labels and not /dev/hdax. Either change fstab and grub.conf to /dev/hdax or add labels to your partitions. |
