Bug Description
Hello,
When configuring DHCP relay on MAAS, if a relay is configured on a VLAN, for example VLAN 41, with a subnet, for example 10.10.21.0/24. If that subnet is then moved to a different fabric, its not possible to disable the relay. The following warning is shown on the MAAS UI:
"No subnets are available on this VLAN. DHCP cannot be enabled." Although the UI shows as DHCP enabled.
[Steps to reproduce]
1. Setup maas with two VLANs, one untagged, one native VLAN for example VID 41, the native VLAN having DHCP forwarded to the untagged VLAN.
2. Setup a DHCP relay to go from 41, to untagged.
3. Configure DHCP relay for VLAN 41 via untagged along with a dynamic range.
4. Create a new fabric, and move the subnet for VLAN 41 to this subnet.
5. Try to disable DHCP relay on VLAN 41.
[Workaround]
Move the subnet back to its original VLAN, and disable DHCP first.
Thanks,
Peter

This limitation exists only in the UI, it's possible to remove the DHCP relay settings using the CLI:
maas $ADMIN vlan update $FABRIC_ID $VID relay_vlan=
