Savanna - Failed to create database

asked 2014-02-24 12:11:07 -0500

Hi,

I have OpenStack Grizzly set up with a controller node and two compute nodes. All systems run Ubuntu 12.04 64-bit.

I followed the following guide : https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst#4-compute-node (https://github.com/mseknibilel/OpenSt...)

Now i am trying to integrate Savanna 0.3 into my setup and i used the following installation guide : https://savanna.readthedocs.org/en/latest/userdoc/installation.guide.html (https://savanna.readthedocs.org/en/la...)

I have set up savanna in a virtual environment.

Now when i try and run savanna by using the command, it fails to create a database. $ savanna-venv/bin/python savanna-venv/bin/savanna-api --config-file savanna-venv/etc/savanna.conf

The following are excerpts from the log.

2014-02-24 17:32:35.697 18858 ERROR savanna.db.sqlalchemy.api [-] Database registration exception: (OperationalError) unable to open database file None None .... 2014-02-24 17:32:35.708 18858 CRITICAL savanna [-] Failed to create database! .... 2014-02-24 17:32:35.708 18858 TRACE savanna raise RuntimeError('Failed to create database!') 2014-02-24 17:32:35.708 18858 TRACE savanna RuntimeError: Failed to create database!

Here is my savanna.conf configuration file :

[DEFAULT]

Hostname or IP address that will be used to listen on

(string value)

#host=

Port that will be used to listen on (integer value)

port=8386

os_auth_host=10.204.142.58 os_auth_port=35357 os_admin_username=admin os_admin_password=password os_admin_tenant_name=service

If set to True, Savanna will use floating IPs to communicate

with instances. To make sure that all instances have

floating IPs assigned in Nova Network set

"auto_assign_floating_ip=True" in nova.conf.If Neutron is

used for networking, make sure that all Node Groups have

"floating_ip_pool" parameter defined. (boolean value)

use_floating_ips=false

Use Neutron or Nova Network (boolean value)

use_neutron=true

Maximum length of job binary data in kilobytes that may be

stored or retrieved in a single operation (integer value)

Maximum length of job binary data in kilobytes that may be

#job_binary_max_KB=5120

Postfix for storing jobs in hdfs. Will be added to

#job_workflow_postfix=

Enables Savanna to use Keystone API v3. If that flag is

disabled, per-job clusters will not be terminated

automatically. (boolean value)

use_identity_api_v3=true

enable periodic tasks (boolean value)

#periodic_enable=true

Enables data locality for hadoop cluster.

Also enables data locality for Swift used by hadoop.

If enabled, 'compute_topology' and 'swift_topology'

configuration parameters should point to OpenStack and Swift

topology correspondingly. (boolean value)

enable_data_locality=false

Print more verbose output (set logging level to INFO instead

of default WARNING level). (boolean value)

verbose=true

use_stderr=true

(Optional) Name of log file to output to. If no default is

set, logging will go to stdout. (string value)

Akshay, check that 'admin' user has admin role in tenant 'services'. It is a requirement for os_admin_username to have admin role in os_admin_tenant_name.

Hello Akshay, try changing 'connection' parameter in your config to connection=sqlite:////tmp/savanna-server.db

It could happen that the default location is not accessible for the user you run Savanna with.

Hi Dmitry, Thanks for your help. I did set the connection parameter as : connection=sqlite:////tmp/savanna-server.db

Now when i try to run savanna, this is what gets generated in the logs. If i try to access savanna through horizon, i get the following error : Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn't help, contact your local administrator.

The logs are as follows :

2014-02-25 13:01:18.431 24139 WARNING keystoneclient.middleware.auth_token [-] Configuring auth_uri to point to the public identity endpoint is required; clients may not be able to authenticate against an admin endpoint

I'm sure I've missed out some key step. I've got OpenStack up and running and I'm able to create VMs. Then i installed savanna 0.3 using the following guide : https://savanna.readthedocs.org/en/latest/userdoc/installation.guide.html (https://savanna.readthedocs.org/en/la...)

Is there anything else that I'm supposed to do? Something that i might have missed? Thanks a lot again.
