Subject [jira] [Created] (CLOUDSTACK-9884) Duplicate of VR after disabling RvR
Date Wed, 19 Apr 2017 10:37:41 GMT
Patrick created CLOUDSTACK-9884:

             Summary: Duplicate of VR after disabling RvR
                 Key: CLOUDSTACK-9884
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
    Affects Versions:
         Environment: CentOS 6.8 + XenServer 6.5
            Reporter: Patrick
            Priority: Critical

Our environment is:
ACS: 4.9.2 (migrated from 4.5.2)
Management Server: CentOS 6.8
Hosts: XenServer 6.5 SP1
System VM: systemvm64template-4.6.0-xen.vhd.bz2
Network: Isolated Network
Network Offering: Offering for Isolated networks with Source Nat service enabled

Issue description:
After the migration to 4.9.2 and the multiple (known) issues with RvR, all networks had their
offerings changed to disable HA and RvR and run networks with a single VR.
Since, the following actions initiate the creation of a "duplicate" second VR, ending in an
UNKNOWN state, and triggering a lot of random network issues.
- New VM instances creation
- Clean restart of the network
Interestingly, when switching between offerings, it also recreates the VR, but it doesn't
do any duplicate this time.

This only impacts networks that were initially set as HA network with RvR. These networks
keep the redundant flag to 1 in the networks table, even though the offering redundant_router_service
flag is set to 0. I believe it should be changed to 0 when the network is using an non-HA
