Subject [jira] [Commented] (CLOUDSTACK-9885) VPC RVR: On deleting first tier and configuring Private GW both VRs becoming MASTER
Date Wed, 17 Jan 2018 06:45:04 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-9885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16328347#comment-16328347
] 

Alexander Conn commented on CLOUDSTACK-9885:
--------------------------------------------

As I needed a fix for this sooner rather than later, I modified the required python scripts
on VR myself. Fortunately the private gateways we use are all part of the same subnet so this
was fixed as per below. My added code in *bold*

+File: /opt/cloud/bin/cs/CsRedundant.py+

 

def _redundant_on(self):

        guest = self.address.get_guest_if()

 

        # No redundancy if there is no guest network

        if guest is None:

            self.set_backup()

            self._redundant_off()

            return

 

        interfaces = [interface for interface in self.address.get_interfaces() if interface.is_guest()]

        isDeviceReady = False

        dev = ''

        for interface in interfaces:

            if dev == interface.get_device():

                continue

 

            *int_ip = interface.get_ip()*

            *if int_ip.startswith('10.200.200.'):*

                *continue*

 

            dev = interface.get_device()

            logging.info("Wait for devices to be configured so we can start keepalived")

            devConfigured = CsDevice(dev, self.config).waitfordevice()

            if devConfigured:

                command = "ip link show %s | grep 'state UP'" % dev

                devUp = CsHelper.execute(command)

                if devUp:

                    logging.info("Device %s is present, let's start keepalive
now." % dev)

                    isDeviceReady = True

 

+File: /opt/cloud/bin/cs/CsAddress.py+

def get_guest_if(self):

        """

        Return CsInterface object for the lowest in use guest interface

        """

        guest_interface = None

        lowest_device = 1000

        for interface in self.get_interfaces():

            *int_ip = interface.get_ip()*

            *if int_ip.startswith('10.200.200.'):*

                *continue*

            if interface.is_guest() and interface.is_added():

                device = interface.get_device()

                device_suffix = int(''.join([digit for digit in device if digit.isdigit()]))

                if device_suffix < lowest_device:

                    lowest_device = device_suffix

                    guest_interface = interface

                    logging.debug("Guest interface will be set on device '%s' and
IP '%s'" % (guest_interface.get_device(), guest_interface.get_ip()))

        return guest_interface

 

Also add this code to all instances of the needs_vrrp function in CsAddress.py, example below:

 

def needs_vrrp(self, o):

        """

        Returns if the ip needs to be managed by keepalived or not

        """

 

        *int_ip = self.get_ip()*

        *if int_ip.startswith('10.200.200.'):*

            *return False*

 

        if "nw_type" in o and o['nw_type'] in VRRP_TYPES:

            return True

        return False

 

Hopefully this helps you guys with your bug fix and anyone else experiencing this issue.
