OpenStack Compute (nova)

Nova does not take into account the quota information

Asked by Jérôme Gallard

Hello,

With the Nova Rev11395 in multizone mode, I have an issue with the quota of instances.
I run the following command:
root@p-novamaster2:~# nova-manage project quota --project=project_admin --key=instances --value=15

It seems that it works because of the following:
root@p-novamaster2:~# nova-manage project quota --project=project_admin
metadata_items: 128
instances: 15
injected_file_content_bytes: 10240
injected_files: 5
volumes: 10
gigabytes: 1000
cores: 20
ram: 51200
floating_ips: 10

However when I try to start more than 10 instances (with nova boot) I got the following answer:
Instance quotas have been exceeded (HTTP 413)

I checked on the mysql database, and it seems that the number of instances is updated to 15.

Do you have an idea about what could be wrong in my configuration ?

Thank you.
Jérôme

you will probably need to update cores and ram as well.

also, if you are using keystone, you need to specify project as the id instead of the name e.g --project=1

Thank you very much for your answer.
The problem was linked to the name of the project. It was not clear that it's mandatory to use the project id.

Can I open a bug to request an update of the documentation ?
Usage: nova-manage project quota <args> [options]

Options:
  -h, --help show this help message and exit
  --project=<Project name>
                        Project name
  --key=<key> Key
  --value=<value> Value

Thank you again,
Jérôme

Just another question linked to the first one, just for my understanding.

I don't understand why the quotas are linked with Keystone. Can you have a look on another question linked to quotas and multi-zone mode ? https://answers.launchpad.net/nova/+question/178179

Thank you very much,
