Hi Guys,

I encountered the following error when I tried to upload a file to swift.

Warning: failed to create container 'container1': 404 Not Found: <html>

Not Found

The resource could not be found.< Object HEAD failed: http://controller:8080/v1/AUTH_xxx/co... 400 Bad Request

Where am I able to check what went wrong?

Cheers, JK

--Update-- I found the following error in my object-server log file:

Mar 12 11:12:09 object1 swift: Exception dumping recon cache: #012Traceback (most recent call last):#012 File "/usr/lib/python2.7/dist-packages/swift/common/", line 2132, in dump_recon_cache#012 with lock_file(cache_file, lock_timeout, unlink=False) as cf:#012 File "/usr/lib/python2.7/", line 17, in __enter__#012 return File "/usr/lib/python2.7/dist-packages/swift/common/", line 1432, in lock_file#012 fd =, flags)#012OSError: [Errno 13] Permission denied: '/var/cache/swift/object.recon'

--update 2-- I found the following issue: I followed the installation guide in openstack website for ubuntu, and set permissions to /var/cache/swift on the storage node to root:swift. However, controller node is not able to access that.

What could be the issue here?

I have confirmed that iptables is not running, and SELinux is not installed. I am using apparmor.

Thank you in advance.

Could you please tell me more about your Openstack version, Operating system etc ?

Hi Bipin, also, I had managed to setup controller and compute node and block storage without any issues, and swift is my first module with errors.

Make sure both admin and demo have SwiftOperator role added

keystone user-role-list --user <username> --tenant admin

You should see something like following

|                id                |      name     | user_id |            tenant_id             |
| b62f29f0a8b345a8a4d2632bd39b4167 | SwiftOperator |  14173  | 069275e634a7420bbbfa4a679aa89fkk |
| 9fe2ff9ee4384b1894a90878d3e9ab2b |    _member_   |  14173  | 069275e634a7420bbbfa4a679aa89fkk |

If you cannot see the SwiftOperator Role, add the role to the tenant like following.

openstack role add --user <username> --project 069275e634a7420bbbfa4a679aa89fkk  SwiftOperator

Hi Bipin,

Is this suitable for Liberty? I understand that keystone command is deprecated.

I missed that point

openstack role add --user username --project TENANT_ID ROLE_NAME SwiftOperator

demo | Demo Project | 47e8331565da4bfdaaf462b9a8a9b5d1

service | Service Project | c27967a5a6d24915a3393b8f8eeac73c    

admin | Admin Project | f619db111afd4cbd818ee15804d7d685

So, does that mean if I want to add the swiftoperator role to demo project i must use the demo project id? Thanks.

Hi Bipin,

I just realised what is going on.
Everything is set under admin role, under the service project. Roles are assigned to both admin and user in the proxy-server.conf, instead of the usual admin and swiftoperator. I am testing out with different port numbers (8080 changed to 8081).

Hi Bipin,

I am only having 1 object storage node with 3 hdd inside, sdb and sdc for swift storage. Is that the issue?

/var/log/messages on swift storage nodes and /var/log/swift/swift.log on swift proxy node should help you find out the exact issue.

I am unable to locate /var/log/swift.

I am using ubuntu 14.04 with Liberty.

@njk84sg have you created the swift endpoint on keystone?

guimaluf gravatar imageguimaluf ( 2016-03-14 06:19:46 -0500 )edit

yes. service name is object-store.

njk84sg gravatar imagenjk84sg ( 2016-03-14 20:15:20 -0500 )edit

sorry. service name is swift, service type of object-store

--update 4 --
Found the issue! :)
When you do swift-ring-builder account.ring add xxx..., please make sure that the port number is 6002.
When you do swift-ring-builder container.ring add xxx...., please make sure that the port number is 6001.
When you do swift-ring-builder object.ring add xxx...., please make sure that the port number is 6000. Problem solved!

-update 3-

I found out that whenever I try to rebalance, I get the following: /usr/lib/python2.7/dist-packages/swift/common/ring/ RingValidationWarning: Replica count of 3.0 requires more than 2 devices 'num_devices': num_devices, No partitions could be reassigned. Either none need to be or none can be due to min_part_hours [1].

Also, when I try to do
swift post container1
I get Container POST failed: http://controller1:8081/v1/AUTH_47e83... 400 Bad Request [first 60 chars of response] Invalid path: /sdb/466/AUTH_47e8331565da4bfdaaf462b9a8a9b5d1

Again, when I enter the disk /sdb/ I do not see 466. I only see accounts and tmp. And also, under accounts, I still do not see 466. I see 513 and 313.

If this is easier for @Bipin or @guimaluf, or everyone, please tell me what I should do.

Cheers, JK
