Openstack : Removing compute node/host
Source is primarily from openstack.org documentation on the net from the installation perspective. However couple of changes on having /dev/sdb created in the RAID, upgrading MariaDB from 10.1 to 10.5 version (challenges with installing neutron services) were some customizations I had done, and have captured the same in my online notes.
