[linux-lvm] Kernel 2.4 -- invalid i/o protocol version

[linux-lvm] Kernel 2.4 -- invalid i/o protocol version

[Ernesto Silva]

Hi guys, 

	I'm having some trouble trying to make LVM work.

	I've recently installed  a new server, runing RedHat 7.0. I have also
installed 2.4 kernel with LM support.

	Then I  have downloaded lvm-0.8final from the sistina ftp site, then I
compiled it (I also included the patch) and I installed it. (well, no eveything
was so smoothly, but it's installed now).

	I can load the lvm-module fine, but when I run vgscan or pvcreate (I
also created a 0x8e type partition in my primary scsi disk) it complains saying
that:  "vgscan -- invalid i/o protocol version"

	Do you have any ideas how to fix it?

I only have one scsi disk of 18GB, but I will add at least another 2 in the
next month, so I need it working. Do you think this will work?? I'm almost
betting my job on it.

thanks

You need to have 0.9 version tools to run with the 2.4 kernel.

Never good to bet your job on things you have not tested.  That way
leads to a new job.  LVM has been _fairly_ reliable, but there have
also been some problems as well - most have been fixable with a bit of
debugging, but...  It is always worthwhile to do testing before putting
a system into production.  Note that you have a far smaller chance of
having serious problems if you ensure you make backups of your data,
and make as few changes to your LVM configuration as possible.

I have never had problems with LVM that I didn't cause myself from
working on the code.  But then again, none of the data I have under
LVM is critical (mostly MP3s and test filesystems), and I have full
backups of everything.

Cheers, Andreas
