Transaction "StartReplication" fails with "Replication source IP list is empty"

Issue

The transaction "StartReplication" fails when using Cloud Motion.

Environment

OnApp versions 5.2-5.6

Resolution

The following procedure can be used as a temporary solution for the issue:

1. Log in via ssh to the CloudBoot Compute Resources:
   

   controlpanel@onapp.cp ~>ssh 192.168.1.38

2. Then using a VI text editor:
   

   [root@192.168.1.38 ~]# vi /scripts/findmyip.sh 

3. Change the contents of the script to the following:
   

   #!/bin/bash
   
   if curl http://216.146.38.70 --connect-timeout 5 2>&1 | grep -q -A1 "Current IP Address:"; then
   
        curl http://216.146.38.70 2>&1 | grep -A1 "Current IP Address:" | sed 's/^.\+Current IP  Address:[[:space:]]\+\([0-9\.]*\)<.\+$/\1/'
   
   else
   
        echo "Your Hypervisor cannot access the public Internet."
   
        echo "We recommend setting up a NAT via your control panel or enabling IP forwarding on your default gateway."
   
   fi

4. Lastly, save the file.
   Perform this procedure on all CloudBoot compute resources and restart the transaction. All failed transactions should work as expected.

Note that you need to perform the above steps each time you reboot a CloudBoot compute resource as the file will be overwritten to the default one.

Cause

This transaction fails due to the IP resolver address not being available in previous CloudBoot Compute Resource RPMs. The IP address is used specifically for the case when the DNS resolver addresses are not configured in CloudBoot Compute Resources. OnApp will provide updated images for 5.5 and newer versions, but in case the fix is needed immediately the abovementioned steps can be applied.
