[linux-lvm] LVM Redhat 7.2 : Volume Group not activated on boot

[Peter Gram]

Hi

I have this problem that I hope some of you out there might be able to 
help with ?

My problem is on boot of the machine I get a  error from the mount 
process that it can not mount and check my file system
"/dev/vg01/vg01lv01" and a option to go into singe user mode where I can 
se that the "vgchange -a y" is not run to activate
the volume group. I have looked at the rc.sysinit and there is this 
entry that should activate all defined volume groups.
Have any of you out in cyberspace seen the same problem with Redhat 7.2 ?

cut from the /etc/rc.d/rc.sysinit :

# LVM initialization
if [ -e /proc/lvm -a -x /sbin/vgchange -a -f /etc/lvmtab ]; then
        action $"Setting up Logical Volume Management:" /sbin/vgscan && 
/sbin/vgchange -a y
fi

My setup :

HP Omnibook 6000 laptop
Redhat 7.2
I have installed the "new" 2.4.17 Linux kernel
VLM support works (That is I can create lv's and I use ext3 file system 
on them)
I have added my lvm to fstab and are able to mount/umount the file 
system without problems

cut from fstab :

/dev/vg01/vg01lv01      /home5/pgram/dev        ext3    defaults        1 2

The problem is the first part of the if statement.  /proc/lvm doesn't exist
unless the lvm-mod module is loaded, and that doesn't happen by default.

On my RH7.2 box, I make initrd's with the "--with=lvm-mod" option so that
initrd forcably loads lvm-mod at bootup.  /proc/lvm then exists, and the
vgchange command is executed.  :)
