After trying to run the core-os installer it fails because it found busy partitions on /dev/sda

100%

1. Install Disconnected SNO cluster (4.14.0-0.nightly-2023-08-21-131444) - Dual Stack
2. Follow steps to add worker node https://docs.openshift.com/container-platform/4.13/nodes/nodes/nodes-sno-worker-nodes.html#sno-adding-worker-nodes-to-single-node-clusters-manually_add-workers

- Boot the live
- configure interface with ipv4/ipv6
- Run the "sudo coreos-installer install --copy-network /
--ignition-url=<new_worker_ign_file> <hard_disk> --insecure-ignition"
3. 

Partitions in use on /dev/sda;  Error: checking for exclusive access to /dev/sda   Caused by: found busy partitions

It should download the cores-installer

I tried to de-active the current lvm called rhel_sno-1
1. sudo vgchange -an rhel_sno-1
2. sudo wipefs -a /dev/sda
3. run "sudo coreos-installer ...."
This allowed the download to take place and completed. 
4. reboot
5. It just booted back to the Coreos live environment
with unconfigured network.
