      Hello Team,

      I tried to run the experiment example “create_l2network_basic_config.ipynb” at site = “TACC” and get the following error, using other sites runs smoothly. I am the maintenance at TACC is over but keep having this issue.

      CODE:

      from ipaddress import ip_address, IPv4Address, IPv6Address, IPv4Network, IPv6Network
      import ipaddress

      from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager

      fablib = fablib_manager()

      fablib.show_config();

      slice_name = ‘MySlice’
      site = “TACC”
      print(f”Site: {site}”)

      node1_name = ‘Node1’
      node2_name = ‘Node2′

      network_name=’net1′

      #Create Slice
      slice = fablib.new_slice(name=slice_name)

      # Network
      net1 = slice.add_l2network(name=network_name, subnet=IPv4Network(“192.168.1.0/24”))

      # Node1
      node1 = slice.add_node(name=node1_name, site=site)
      iface1 = node1.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
      iface1.set_mode(‘config’)
      net1.add_interface(iface1)
      iface1.set_ip_addr(IPv4Address(“192.168.1.1”))

      # Node2
      node2 = slice.add_node(name=node2_name, site=site)
      iface2 = node2.add_component(model=’NIC_Basic’, name=’nic1′).get_interfaces()[0]
      iface2.set_mode(‘config’)
      net1.add_interface(iface2)
      iface2.set_ip_addr(IPv4Address(“192.168.1.2”))

      #Submit Slice Request

      slice.submit();

      ERROR:

      failed lease update- all units failed priming: Exception during create for unit: 9d37f657-03b9-4301-803b-7b2804308294 Playbook has failed tasks: Error in creating the server (no further information available)#all units failed priming: Exception during create for unit: 9d37f657-03b9-4301-803b-7b2804308294 Playbook has failed tasks: Error in creating the server (no further information available)#

        Hi Acheme,

        Thank you for reporting this issue. TACC worker tacc-w1 where VMs were spawned had issues. We have recovered the worker and provisioning should work now.

        Thanks,

        Komal

          I tried again and it creates the slice but sets the network of node interfaces to “None” for some reason.

            Hi Acheme,

             

            We are noticing intermittent connectivity issues with TACC switch, resulting in the Network Services failing to provision. That’s resulting the Network being set to None. We are working to resolve this issue and will keep you posted.

             

            Thanks,

            Komal

              Should be resolved now. I just tried a slice and it worked.

              Thanks,

              Komal
