FC6->FC7 Kernel Panic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm attempting to upgrade one of my servers from FC6-FC7 on the way to FC8. I followed all the recommendations including the disk LABELs, etc and everything seemed to work. But once I rebooted I got a kernel panic because my /boot directory can't be found.

I have two IDE drives both LVM managed except for a small boot partition on the first drive. I can boot back to FC6 just fine, but get the kernel panic when I try the FC7 kernel. My grub.conf looks like this:


# 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/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.23.15-80.fc7)
        root (hd0,0)
        kernel /vmlinuz-2.6.23.15-80.fc7 ro root=LABEL=/boot
        initrd /initrd-2.6.23.15-80.fc7.img
title Fedora Core (2.6.22.14-72.fc6)
        root (hd0,0)
kernel /vmlinuz-2.6.22.14-72.fc6 ro root=/dev/VolGroup00/LogVol00 hdc=ide_scsi
        initrd /initrd-2.6.22.14-72.fc6.img


After the first time I booted I changed the FC7 kernel line, it originally looked the same as the FC6 line. That didn't help. My fstab looks like this:

/dev/VolGroup00/LogVol00 /                      ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
sysfs                   /sys                    sysfs   defaults        0 0
/dev/VolGroup00/LogVol01 swap                   swap    defaults        0 0
LABEL=SATA1             /mnt/sata1              ext3    defaults        0 0
LABEL=SATA2             /mnt/sata2              ext3    defaults        0 0

The bottom two entries are partitions I have on a supplemental SATA drive.

sfdisk reports this:

For this listing I'll assume that geometry.

Disk /dev/dm-1: 118 cylinders, 255 heads, 63 sectors/track

The ERROR's gave me pause, but I'm booting FC6 ok. Could this be the problem?

Any advice would be great.  I can post more information if it would help.
