UPDATE changing title to be more clear
Hi all,
I’m trying to setup a three node lxd cluster assigning a class B IP v4 network address.
When I try lxd init (I have version 3.13 installed with snap) i got the error
Error: Failed to create network ‘lxdfan0’: Not an IPv4 network address: 10.10.0.1/16
When asked by lxd init I replied:
What subnet should be used as the Fan underlay? [default=auto]: 10.10.0.1/16
What is the correct method to assign more than 256 addresses to lxdfan0?
UPDATE:
Found this in doc ( https://lxd.readthedocs.io/en/latest/networks/ )
fan.overlay_subnet string fan mode 240.0.0.0/8 Subnet to use as the overlay for the FAN (CIDR notation)
But this address is not accepted by lxd init:
Would you like to create a new Fan overlay network? (yes/no) [default=yes]:
What subnet should be used as the Fan underlay? [default=auto]: 240.0.0.0/8
Invalid input: The underlay subnet must be a /16 or a /24
What subnet should be used as the Fan underlay? [default=auto]: 172.16.0.0/16
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]
Would you like a YAML “lxd init” preseed to be printed? (yes/no) [default=no]:
Error: Failed to create network ‘lxdfan0’: No address found in subnet
What can I do?
UPDATE 2
Strangely this address was refused
sysop@kvmnode1:~$ lxc network create fanbr0 bridge.mode=fan fan.underlay_subnet=172.30.0.0/16
Error: No address found in subnet
but this one is accepted
sysop@kvmnode1:~$ lxc network create fanbr0 bridge.mode=fan fan.underlay_subnet=192.168.0.0/16
Network fanbr0 created
sysop@kvmnode1:~$ lxc network show fanbr0
config:
bridge.mode: fan
fan.underlay_subnet: 192.168.0.0/16
description: “”
name: fanbr0
type: bridge
used_by:
managed: true
status: Created
locations: - none
I fear that this settings conflicts with the three network cards of the node:
ens3 192.168.202.11
ens4 192.168.200.11
ens5 192.168.201.11
Is it correct or it is a bug?
