[linux-lvm] invalid i/o protocal version

[Adam Crews]

Hello

I have just downgraded from kernel 2.4.0-test1 to 2.2.16.

I installed the lvm patch to 2.2.16 and can load the lvm module just fine.
[root at scooby /root]# lsmod

[root at scooby /root]# cat /proc/lvm

When I try to do any lvm commands I get the following:
[root at scooby /root]# vgscan -d -v
<1> lvm_get_iop_version -- CALLED
<22> lvm_check_special -- CALLED
<22> lvm_check_special -- LEAVING
<1> lvm_get_iop_version -- AFTER ioctl ret: 0
<1> lvm_get_iop_version -- LEAVING with ret: 5
vgscan -- invalid i/o protocol version

[root at scooby /root]#


I have re-compiled the lvm tools against the 2.2.16 src and libs, but I
get the same message.

How can I fix this, or what other info is needed to figure out what is
happening?
