$ nova help quota-update

Object Storage quotas can be classified under the following categories:

To set either container quotas or the account quotas, the Object Storage proxy server must have the parameters container_quotas or account_quotas (or both) added to the [pipeline:main] section of the proxy-server.conf file:

[pipeline:main]
pipeline = catch_errors [...] tempauth container-quotas \
account-quotas slo dlo proxy-logging proxy-server

[filter:account_quotas]
use = egg:swift#account_quotas

[filter:container_quotas]
use = egg:swift#container_quotas

Use the following command to view and update the Object Storage quotas. All users included in a project can view the quotas placed on the project. To update the Object Storage quotas on a project, you must have the role of a ResellerAdmin in the project.

To view account quotas:

# swift stat

Account: AUTH_b36ed2d326034beba0a9dd1fb19b70f9
Containers: 0
Objects: 0
Bytes: 0
Meta Quota-Bytes: 214748364800
X-Timestamp: 1351050521.29419
Content-Type: text/plain; charset=utf-8
Accept-Ranges: bytes

To update quotas:

# swift post -m quota-bytes:<BYTES>

For example, to place a 5 GB quota on an account:

# swift post -m quota-bytes:5368709120

To verify the quota, run the swift stat command again:

# swift stat

Account: AUTH_b36ed2d326034beba0a9dd1fb19b70f9
Containers: 0
Objects: 0
