installed, I want to test GFS under gnbd, when i create LVM, I recive
error messages. This is my approach:

# dd if=/dev/zero of=/tmp/testgnbd bs=1M count=1023
1023+0 records in
1023+0 records out

# modprobe gnbd

# gnbd_serv
gnbd_serv: startup succeeded

# gnbd_export -d /tmp/testgnbd -e testgnbd -c
gnbd_export: created GNBD testgnbd serving file /tmp/testgnbd

# gnbd_import -i localhost
gnbd_import: created directory /dev/gnbd
gnbd_import: created gnbd device testgnbd
gnbd_recvd: gnbd_recvd started

# pvcreate /dev/gnbd/testgnbd

# vgcreate testvg /dev/gnbd/testgnbd

#  lvcreate -L 1000 -n testlv testvg
  Error locking on node ECGL2-a5770c: Internal lvm error, check syslog

#  tail /var/log/messages

  Found volume group "testvg" using metadata type lvm2

#lvscan
