Hi everyone

I have deployed devstack as per instructions in pdf, on Ubuntu 16.04, KVM with Ubuntu 16.04, 7 CPU and 12 GB of RAM and 40/100 GB disk
on my desktop and also on my laptop - almost identical setups.

I can log in OK, and as a admin i was able to create 1 vm.
During lab 3.1 i created additional user and tried to start another instance. On both setups it comes up with an error message:

Build of instance 4f0542bc-f53c-4686-95d2-cd37d8c82553 aborted: Volume 6731e568-1239-4bc1-a1e7-231979ddfd5a did not finish being created even after we waited 0 seconds or 1 attempts. And its status is error.

Code
500

I then tried logging back on as admin to test if its permission/quota or something else, but now i can not create new instance as a admin user either.
Tried googling but below solution did not resolve my problem.
https://ask.openstack.org/en/question/109842/devstack-fails-instance-creation-other-than-tiny/

I reviewed https://docs.openstack.org/devstack/latest/ to see if there are any additional specific options are reuired but i dont see any.

Anyone else saw or had similar issues?
Thanks
Bogdan

    so digging into errors now:

    $ sudo journalctl -f --unit devstack@c-vol
    ERROR cinder.service [-] Manager for service cinder-volume devstack1@lvmdriver-1 is reporting problems, not sending heartbeat. Service will appear "down".

    i do not seem to have service that error message is compaling about:
    $ sudo systemctl list-units | grep lvm
    lvm2-lvmetad.service loaded active running LVM2 metadata daemon
    lvm2-monitor.service loaded active exited Monitoring of LVM2 mirrors, snapshots etc. using dmeventd or progress polling
    lvm2-lvmetad.socket loaded active running LVM2 metadata daemon socket
    lvm2-lvmpolld.socket loaded active listening LVM2 poll daemon socket

    Thank you Mr Serewicz. I figured out what it was... I rebooted the instance and was able to successfully replicate this behaviour. Devstack, unfortunately, doesn't survive this action(reboot). Should have remembered that from pdf where you mentioned it.. (Facepalm)
