I have a problem I'm trying to solve but I haven't found a solution.
I am running FC4 (with AMD64) and was able to boot the machine without
problems until Friday when I had to change my motherboard.
Since then it appears that I'm unable to boot because the system can not
find my LVM. I see this error message after grub selected the OS:
Red Hat nash version 4.2.15 starting
Reading all physical volumes. This may take a while ...
No volume groups found
Unable to find volume group "VolGroup00"
and as a result a kernel panic.
I can start the machine by using the installation disk and boot with
'linux rescue' and then I can see my volume and access the data.
I have two SATA hard drives with a /boot partition and the volume group
on the first one and the second HDD has just regular partitions:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol04 15G 7.2G 6.4G 54% /var
/dev/mapper/VolGroup00-LogVol03 34G 12G 20G 37% /backup
/dev/mapper/VolGroup00-LogVol00 24G 7.9G 15G 35% /
/dev/sda1 99M 29M 65M 31% /boot
/dev/sdb3 138G 18G 113G 14% /free
/dev/mapper/VolGroup00-LogVol02 29G 3.4G 24G 13% /home
/dev/sdb2 46G 1.2G 43G 3% /home/public
/dev/sdb1 46G 706M 43G 2% /home/mail
Why would the boot process not find my volume group but does when I'm
starting the OS with the rescue disk (or Knoppix)?
