Re: [linux-lvm] pvscan - - invalid i/o protocol version



Thanks for your reply.

I did have the LVM module loaded. I don't know what the problem was. Probably incompatibility between Kernel module, and program version or something.

Was able to resolve the issue by upgrading to version 0.9-1 "redhat binary".

Cheers,
Pascal

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?
