[linux-lvm] Problem doing basic LVM functions

[Ricardo Sanchez]

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

And it just hangs there. Can anyone help?
