Completely remove openstack from system after installation from devstack script

Question

I am installing OpenStack on my local machine via this link. But I am having trouble in completely removing installed components from my local machine. I ran following command:-

$ sudo ./unstack.sh
tgtadm: can't send the request to the tgt daemon, Transport endpoint is not connected
tgtd seems to be in a bad state, restarting...
stop: Unknown instance: 
tgt start/running, process 14629
tgt stop/waiting
Volume group "stack-volumes" not found
Skipping volume group stack-volumes

And file are still present in /opt/stack and /usr/local/bin/. But manually removing these file will not be a good option.

Answer 1

The unstack.sh script only stops the services without removing them. Devstack's folder contains a clean.sh script that removes openstack and dependencies so you can run something like this:

cd path/to/devstack

# There's no need to call unstack.sh explicitly
# clean.sh invokes that script itself.
./clean.sh

Answer 2

Follow the following 3 steps:

1. ./clean.sh
2. rm -rf /opt/stack
3. rm -rf /usr/local/bin (careful, this will remove everything installed to your local bin folder, which might include previously installed applications).
