The --verbose flag is passed through to ansible runs in the provision command, so this will provide more verbose logging: openstack -vvv overcloud node provision On 6/07/23 22:13, Lokendra Rathour wrote:
Hi Team,
Scenario: We were performing overcloud deployment. During this, we were continuously facing the following errors on two of the nodes out of the four nodes:
PLAY [Overcloud Node Grow Volumes] ********************************************* 2023-06-02 19:07:33.483504 | 52540049-4965-0177-e681-00000000000a | TASK | Wait for provisioned nodes to boot [WARNING]: Unhandled error in Python interpreter discovery for host overcloud- controller-0: Failed to connect to the host via ssh: ssh: connect to host 30.30.30.219 port 22: No route to host [WARNING]: Unhandled error in Python interpreter discovery for host overcloud- controller-0: Failed to connect to the host via ssh: ssh: connect to host 30.30.30.219 port 22: Connection refused
We faced this error when we were performing overcloud node provisioning.
To resolve this issue, we had to update the image and create a user to access the nodes. We were able to access the nodes via this user through the BMC console.
This implied that OS was getting correctly installed on the node. Once we accessed the logs on the failed node we came across the following logs:

As we can see in the above logs, only 7 nics are active. But as per our bond config file, we required 8 interfaces: a. nic-1 for management IP b. nic-3 and nic-4 for the br-tenant-2 network. c. nic-5 and nic-6 for the br-tenant network. d. nic-7 and nic 8 for the br-ex network.
The wire was faulty in this case and hence only 7 interfaces were available
Query: The logs which are visible while we run "openstack overcloud node provision" are not very informative. Is there any way where we could get these logs on the undercloud node itself? This could save some time for future references
