ERRATA CORRIGE:
The Network restart is triggered using the UI WITH "Clean Up" set and without
"Make redundant" enabled.

Dear Cloudstack-Developers,
a Network restart triggered using the UI (without "Clean up" and without "Make
redundant" enabled) fails with:
"Can't find all necessary running routers!"
I have looked up the source code for it and came to the following relevant
snippet in
server/src/main/java/com/cloud/network/element/VirtualRouterElement.java
starting at line 234:
###
if (offering.isRedundantRouter() || network.isRollingRestart()) {
expectedRouters = 2;
}
###
From the log files I see that a rollingRestart is indeed triggered, but why
does it expect two routers then? Because there might be two routers running
simultaneously during the restart? If that was the case, then why in the
following lines, relevant snippet (starting at line 237):
###
if (routers == null || routers.size() < expectedRouters) {
//we might have a router which is already deployed and running.
//so check the no of routers in network currently.
List<DomainRouterVO> current_routers =
_routerDao.listByNetworkAndRole(network.getId(), Role.VIRTUAL_ROUTER);
if (current_routers.size() < 2) {
updateToFailedState(network);
throw new ResourceUnavailableException("Can't find all
necessary running routers!", DataCenter.class, network.getDataCenterId());
}
}
###
is throwing an Exception when current_routers.size() is smaller than 2 and not
smaller than 1?
I understand that the logic is designed towards more complex networks, but will
this logic not always fails for an already implemented BASIC network on KVM,
with no redudant routers enabled and one VR already active?
Please let me know what I am missing, I attach the relevant log file inline at
the end of this message.
Sincerely,
Thomas Moroder
