Issue creating a slice at TACC

[Acheme Acheme]

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:

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,

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,

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

Thanks,

Komal
