ok, i agree that will take care of the problem. however, even when i clone a system without lvm it will not load my scsi_hostadapter. also, perhaps lvm is built into the kernel and there would not be a use for "pre-install" for lvm-mod.
what is strange is that after the system boots i am able to do a modprobe of my scsi_hostadapter and then mount my filesystems.
Is this even for non-lvm systems? You should be able to do
mount /dev/sda1 /mnt/foo
for example, and have scsi_hostadapter loaded automatically. In fact, a line with sd-something in fstab should also trigger scsi_hostadapter to be loaded, except for the root fs.
i will have to take another close look at my /etc/modules.conf because as you indicate any access to /dev/sda should prompt kerneld to load scsi_hostadapter. on my first investigation it appeared that ANY scsi support necessary had to be included in the initrd (whether or not it was needed for the root filesystem). is there anywhere else i need to check to make sure my scsi_hostadapter gets loaded on boot besides /etc/modules.conf? it was set to "off" before. how does the system know to load sd_mod? anytime a sd device is accessed?
why was the module not loaded on boot from the modules listed in modules.conf? what part of the boot process actually loads the "scsi_hostadapter" module line in the modules.conf?
modules.conf is a config file for the kerneld module loader. As soon as a scsi device in /dev is opened, it should trigger scsi_hostadapter to be loaded, assuming the root file system is mounted, naturally.
It's possible that vgscan tries to be clever and not go through all devices in /dev, and only look at those in /proc/scsi/scsi or something, which won't trigger kerneld.
vgscan runs but cant find any devices related to its volume groups because the scsi modules havent loaded. the first thing i need to do is get my scsi modules to load on boot. which i havent been successful in doing yet
