Devstack 多节点安装

Question

I'm going through the multi-node installation tutorial and I get errors when trying to configure the Worker Node:

 +lib/lvm:_create_lvm_volume_group:114      sudo vgcreate stack-volumes-lvmdriver-1 /dev/loop1
  Physical volume '/dev/loop1' is already in volume group 'stack-volumes-lvmdriver-1'
  Unable to add physical volume '/dev/loop1' to volume group 'stack-volumes-lvmdriver-1'
  /dev/loop1: physical volume not initialized.

....

nova-compute: no process found
neutron-openvswitch-agent: no process found
+./stack.sh:exit_trap:524          exit 1

Here is my config file:

HOST_IP=192.168.122.129
FIXED_RANGE=10.4.128.0/20
FLOATING_RANGE=129.168.122.128/25
LOGFILE=/opt/stack/logs/stack.sh.log
ADMIN_PASSWORD=asti
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
DATABASE_TYPE=mysql
SERVICE_HOST=192.168.122.129
MYSQL_HOST=$SERVICE_HOST
RABBIT_HOST=$SERVICE_HOST
GLANCE_HOSTPORT=$SERVICE_HOST:9292
ENABLED_SERVICES=n-cpu,q-agt,c-vol,placement-client
NOVA_VNC_ENABLED=True
NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_lite.html"
VNCSERVER_LISTEN=$HOST_IP
VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN

So the first question is what's the problems seems to be?

I gave my machine 4096 RAM and 1 CPU (it's suppose to be a small compute node).

Second ,what are the HOST_IP and SERVICE_HOST suppose to mean? Do they point to this machine or the Controller Node?

Furthermore , in the example the the FLOATING_RANGE=192.168.42.128/25 but the IP are 192.168.42.11 which fall outside of the range.

Here is how I set the IP on this worker node:

stack@ubuntu:~/devstack$ cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: yes
      addresses:
        - 192.168.122.129/24
      gateway4: 192.168.122.1

And the output of ip addr :

Answer 1

SERVICE_HOST is the Control Node IP

You are getting the error because you set the SERVICE_HOST and HOST to same host IP.

also, once nodes are up run this from the devstack directory on Control node:

./tools/discover_hosts.sh
