-------------------------------------------
Summary: No HA for redundant routers
Key: CLOUDSTACK-4374
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4374
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Virtual Router
Affects Versions: 4.1.0
Reporter: Roeland Kuipers
We provide redundant routers with HA functionality through a special service
offering.
However these router pairs are provisioned with ha_enabled=0, so when one or
both of them fail they will never be restarted by CS.
2013-08-16 15:51:16,101 DEBUG [cloud.ha.HighAvailabilityManagerImpl]
(HA-Worker-0:work-4335) VM is not HA enabled so we're done.
This is currently hardcoded in VirtualNetworkApplianceManagerImpl.java @ 1633
boolean offerHA = routerOffering.getOfferHA();
/* We don't provide HA to redundant router VMs, admin should
own it all, and redundant router themselves are HA */
if (isRedundant) {
offerHA = false;
}
We like redundancy and like to have HA on our redundant routers. We like to
configure this ourselves through service offerings and do not like being helt
hostage by these lines of codes:) We do like to own it all in our admin role :)
Besides this, this is also very counter-intuitive as we were expecting HA on
our redundant routers, since it was configured on their service offering.
So can we get rid of these lines of code? And have this controlled through
service offerings as it should IMHO.? Unless this has negative impact which we
are not aware off?
Cheers & Thanks,
Roeland

bug 12608: NaaS: Don't shutdown elements if cleanup=false
We can use the restartNetwork mechanism to recover the disconnected redundant
router.
Also disable HA for redundant router. Admin would take responsibilty to recover
the failure router, because redundant routers themselves are one layer HA.
status 12608: resolved fixed
