Hi,

I'm new to LVM, and desperate to get it working on a 3 disk linux box. I'm running Kernel version 2.4.6, and installed the binary 'RedHat'

version

8.1 of LVM.
I have compiled the kernel with LVM as a module, and everything seems to work fine at bootup (/proc/lvm is there).
The module is loaded at bootup, and i put the vgscan and vgchange

scripts in

rc.sysinit.

I have changed the partition type of hdb, and hdc to 0x8e. But when i

try to

run pvcreate /dev/hdb1 i get:

pvcreate - - ERROR: "/etc/lvmtab" doesn't exist; please run vgscan.

And when i run vgscan:

vgscan - - invalid i/o protocol version

What did i do wrong? Did i install the wrong version of LVM? Any help will be greatly appreciated.

You don't have the driver in your kernel.

Check in your kernel configuration if LVM is activated.

In case you've got the driver as a module, you need to load it manually or preferably have it loaded by kmod. Maybe your modules.conf doesn't cover the LVM module load?
