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

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
root=LABEL=/boot clearly is wrong. The kernel root= parameter specifies
the system's root partition, but LABEL=/boot points to your
/boot partition instead, /dev/sda1 = (hd0,0).
Yes my mistake, see below.
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.
That's strange.
I guess it would be if I could type. The /boot label thing was just
wrong, I don't know where I picked that up from. The original fc7
kernel line was:
kernel /vmlinuz-2.6.23.15-80.fc7 ro root=/dev/VolGroup00/LogVol00
hdc=ide_scsi
... very _similar_ to the original fc6 line.
Its funny because the only thing that isn't volume managed is the /boot
partition, which is labeled. My understanding was that LVM managed
partitions don't require labeling.
I also thought I read that all drives were now treated as SCSI drives.
With that in mind I tried removing hdc=ide_scsi to see if that would
make any difference. That didn't really help either. But I can still
boot up FC6 without a problem.
If anybody has any ideas I'd certainly appreciate it.
Thanks.
