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

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:
Disk /dev/hda: 3148 cylinders, 16 heads, 63 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/255/63 (instead of 3148/16/63).
For this listing I'll assume that geometry.

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.
TIA - Tod
Correction: The panic is related to the message I get at boot saying
could not find filesysytem /dev/root.
