Are you trying to use nbd nodes in LVM?
I had the same problem using nbd & LVM. I first had to destroy & recreate the nbd nodes. I put each nbd node into a single disk md, & used the md nodes in my pv & vg.
Been working fine that way for several months now, although running locate to find a file would crash the system, so I removed the slocate rpm.

Thanks for the reply. I am not using nbd nodes...the kernel started throwing
out those messages I have never worked with nbd nodes. How can I destroy the
nbd nodes? I just want to start all over again but can't. Every time I try
to do lvm functions, it hangs on those messages.
Thanks
Ricardo

blind guess, lvm sometime do block device scan and search for metadata,
u happen to have nbd module available or compiled in kernel. so if you
set a skip list for all u nbd devices, or disable the nbd in u kernel, u
might be able to solve this.
but nbd code should check if nbdX is configured or not.

Try editing the filters in the devices section of your lvm.conf so lvm will only try to use the disks you want. Valid for lvm version 2 only.
I use lvm on many systems ( all RH or RH clones ) and the only system that had your same problem is the one on which I played with nbd.

I created a basic volume group named "uservg" and added two PVs to it
successfully.
After doing this, I deleted the partitions to the disks...
Every time I try to do a vgscan or vgremove it gives the following output:
nbd0: Attempted send on closed socket
end_request: I/O Error, dev nbd0, sector 0
printk: 7 messages suppressed.
Buffer I/O Error on device nbd0, logical block 0
Buffer I/O Error on device nbd0, logical block 1
