Hi.=20
Just upgraded a small 3 nodes cluster to 6.4 today. This cluster used the S=
DN feature with a single VLAN zone, and a few vnets (each one of the vnets =
using a VLAN tag, and not VLAN-aware themself).=20
I see several issues regarding SDN since the upgrade :=20
* The biggest issue is that in Datacenter -> SDN I only see a single no=
de (with the status "available"). The other two do not appear anymore. With=
out paying attention, I clicked on the "Apply" button. This wiped the /etc/=
network/interfaces.d/sdn file on the 2 nodes which do not appear anymore, a=
nd reloaded their network stack. Needless to say it was a complete failure =
as all the VM attached to one of those vnets lost network connectivity. I'v=
e manually copied this /etc/network/interfaces.d/sdn file from the only wor=
king node to the other two for now, but I can't make any change from the GU=
I now or it'll do the same again=20
* In Datacenter -> SDN -> Zones, my single zone didn't appear anymore. =
No Zone were displayed at all. But the Vnets correctly showed they were att=
ached to my zone. /etc/pve/sdn/zones.cfg correctly had my zone defined here=
. I tried adding it again from the GUI, which seemed to work. The only chan=
ge it made to /etc/pve/sdn/zones.cfg is the new "ipam: pve" option added to=
the existing zone=20
Anyone know what could be wrong ? Why would 2 (out of 3) nodes not showing =
up in the SDN status anymore ?=20
