2017-07-22 11:25:32 -0600 asked a question DevStack: Could not find a version that satisfies the requirement pbr===1.10.0

I have been using the stable/ocata branch of DevStack for the last couple of months without any problems. However when I tried to run stack.sh today I got this error;

Could not fetch URL https://pypi.python.org/simple/pbr/: There was a problem confirming the ssl certificate: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed - skipping
  Could not find a version that satisfies the requirement pbr===1.10.0 (from -c /opt/stack/requirements/upper-constraints.txt (line 262)) (from versions: )
No matching distribution found for pbr===1.10.0 (from -c /opt/stack/requirements/upper-constraints.txt (line 262))

When I try to install pbr I have using pip install pbr in fact pip say that pbr is already installed Requirement already satisfied: pbr===1.10.0 in /usr/local/lib/python2.7/dist-packages Howver DevStack attempts to install it again and fials. I also tried to uninstall pbrand install it again using pip. I got no SSL errors, the problem seems to occur only when running stack.sh

2017-07-20 11:02:01 -0600 asked a question How do I boot from image and create a volume

I want to create a new instance from an image using nova boot and create a new volume

In the help of nova boot I found the following:

--block-device-mapping <dev-name=mapping>
                                Block device mapping in the format <dev-
                                name>=<id>:<type>:<size(GB)>:<delete-on-
                                terminate>.

How do I know what ID to specify, the volume does not exist yet?

The command I have until now is:

nova boot cmdtest2 --flavor cirros64 --image cirros-0.3.4-x86_64-uec --block-device-mapping /deb/vda=<ID>:disk:10:False

What do I have to specify insted of <ID> ?

2017-04-04 09:54:01 -0600 asked a question devstack no hosts available

I am trying to run a devstack installation from the stable/ocata branch. At first I got the following error No hosts found to map to cell, exiting” I solved it by adding enable_service n-cell to my local.conf, so now the file looks like this

[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
IP_VERSION=4
enable_service n-cell
RECLONE=yes

The installation completed successfully, however when I try to create new cirros vm I am getting the following error:

 No valid host was found. There are not enough hosts available

From the screen session I see that n-cond n-cell-region n-cell-child n-sch n-cauth and n-cpu are running. In the scheduler log I found the following error

2017-04-04 15:47:53.219 DEBUG nova.filters [req-7ae99e00-ddcc-492f-b061-805aa4314cee admin

dmin] Filter RetryFilter returned 0 hosts

In nova-cells.conf I see the following filters are enabled:

scheduler_default_filters = RetryFilter,AvailabilityZoneFilter,RamFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,SameHostFilter,DifferentHostFilter

I don't see anything wrong in the config, the only thing that bothers me is enable_service n-cell, because I never needed it to run devstack. Any ideas why the scheduler is starting with 0 hosts

2017-02-18 14:42:07 -0600 asked a question Devstack: Invalid credentials after reboot. Keyostone error 404

I am trying to run Devstack, my local.conf looks like this

[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

When I run ./stack.sh everything works as expected. I am able to access horizon, create instances, etc. Before shutting down the machine I run ./unstack.sh. When I later start the machine again I start devstack by using screen -c stack-screenrc. I am able to access horion, however when I try to log in I get an invalid credentials error. I looken in horizon screen and I saw the following errors

2017-02-18 16:51:18.687058 DEBUG:keystoneauth.identity.v3.base:Making authentication request to http://192.168.2.102/identity/v3/auth/tokens

2017-02-18 16:51:18.725569 Login failed for user "demo", remote address 192.168.2.101.

If I run ./stack.sh again everything works until reboot/shutdown. Am I doing somehting wrong wrong when starting devstack after reboot? I don't wan't to run ./stack.sh evrytime since it takes a long time to complete and I don't want to wipe my data.
