  • I recently tested this using wireshark. When I run packet capture on nic1 of dstPC I see ping request packets coming, but no response packets leaving the interface. On nic2 I don’t see any packets leaving either. So kind of stumped what is happening. It seems the computer just drops the response packet and it never makes it till any nic. But still don’t have a good explanation of WHY the packet gets dropped.


  • OK this is what I was thinking too. So consider this scenario:

    srcPCnic1 - 192.168.1.100/24 DG: 192.168.1.1 dstPCnic1 - 192.168.2.100/24 dstPCnic2 - 192.168.1.101/24 DG: 192.168.1.1

    Topology: srcPCnic1 -> RTR -> dstPCnic1 Assume srcPCnic1 is also connected to dstPCnic2 via a switch. (Sorry if its difficult to imagine with the crude description)

    On srcPC execute: ping 192.168.2.100 RTR will route the packet to dstPC. dstPC receives the packet on nic1. dstPC sends the Response packet via nic2.

    Is the above understanding correct?

    Figured it out. I had created 3 VMs but was trying to created shared storage between 2 xcp-ng instances. I assumed that this can be done and the 3 instance will only act as witness without contributing to the storage.

    After going through many replies on the forum thread I understood that you need minimum 3 hosts participating in the storage. Modified my setup to match the requirements (was easy since they are just VMs) all the instructions worked correctly.

    The error about missing linstor python module was that I hadn’t installed necessary packages on 3rd host in the pool since I assumed it doesn’t require XOSTOR instructions to be run on it since it would not be participating in shared storage. This is my understanding though and I can be wrong.

    Having written above I think I can still have only 2 hosts participating in storage but just need to install necessary packages on third host also. Will try and see how it goes.
