Wanted to remove a compute node from the openstack setup. Stop the services in the compute node service nova-compute stop service neutron-linuxbridge-agent stop # Not sure about the need for stopping the following but did it as I had planned to re-install service lvm2-lvmetad stop service libvirtd stop service lxcfs stop service tgt stop On…

Cinder – Block storage services – Storage Nodes
In my case all the three compute nodes will also be storage nodes. In all the three nodes had created a single virtual disk in RAID controller. /dev/sda1 was use for efi boot and /dev/sda2 for OS installation. a new partition /dev/sda3 was created for the remaining space. Install the supporting utility packages apt install…
