Swift and Ceph

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All,

 

I was hoping for some advice.   I have recently built a Ceph cluster on RHEL 6.5 and have configured RGW.      I want to test Swift API access, and as a result have created a user, swift subuser and swift keys as per the output below:

 

1.       Create user

 

radosgw-admin user create --uid="testuser1" --display-name="Test User1"

{ "user_id": "testuser1",

  "display_name": "Test User1",

  "email": "",

  "suspended": 0,

  "max_buckets": 1000,

  "auid": 0,

  "subusers": [],

  "keys": [

        { "user": "testuser1",

          "access_key": "MJBEZLJ7BYG8XODXT71V",

          "secret_key": "tGnsm8JeEgPGAy1MGCKSVVoSIEs8iWNUOgiJ981p"}],

  "swift_keys": [],

  "caps": [],

  "op_mask": "read, write, delete",

  "default_placement": "",

  "placement_tags": [],

  "bucket_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "user_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "temp_url_keys": []}

 

2.       Create subuser.

 

radosgw-admin subuser create --uid=testuser1 --subuser=testuser1:swift --access=full

{ "user_id": "testuser1",

  "display_name": "Test User1",

  "email": "",

  "suspended": 0,

  "max_buckets": 1000,

  "auid": 0,

  "subusers": [

        { "id": "testuser1:swift",

          "permissions": "full-control"}],

  "keys": [

        { "user": "testuser1:swift",

          "access_key": "HX9Q30EJWCZG825AT7B0",

          "secret_key": ""},

        { "user": "testuser1",

          "access_key": "MJBEZLJ7BYG8XODXT71V",

          "secret_key": "tGnsm8JeEgPGAy1MGCKSVVoSIEs8iWNUOgiJ981p"}],

  "swift_keys": [],

  "caps": [],

  "op_mask": "read, write, delete",

  "default_placement": "",

  "placement_tags": [],

  "bucket_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "user_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "temp_url_keys": []}

 

3.       Create key

 

radosgw-admin key create --subuser=testuser1:swift --key-type=swift --gen-secret

{ "user_id": "testuser1",

  "display_name": "Test User1",

  "email": "",

  "suspended": 0,

  "max_buckets": 1000,

  "auid": 0,

  "subusers": [

        { "id": "testuser1:swift",

          "permissions": "full-control"}],

  "keys": [

        { "user": "testuser1:swift",

          "access_key": "HX9Q30EJWCZG825AT7B0",

          "secret_key": ""},

        { "user": "testuser1",

          "access_key": "MJBEZLJ7BYG8XODXT71V",

          "secret_key": "tGnsm8JeEgPGAy1MGCKSVVoSIEs8iWNUOgiJ981p"}],

  "swift_keys": [

        { "user": "testuser1:swift",

          "secret_key": "KpQCfPLstJhSMsR9qUzY9WfA1ebO4x7VRXkr1KSf"}],

  "caps": [],

  "op_mask": "read, write, delete",

  "default_placement": "",

  "placement_tags": [],

  "bucket_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "user_quota": { "enabled": false,

      "max_size_kb": -1,

      "max_objects": -1},

  "temp_url_keys": []}

 

When I try and do anything using the credentials above, I get “Account not found” errors as per the example below:

 

swift -A https://<FQDN>/auth/1.0 -U testuser1:swift -K "KpQCfPLstJhSMsR9qUzY9WfA1ebO4x7VRXkr1KSf" list

 

That’s the first thing.

 

Secondly, when I follow the process above to create a second user “testuser2”, the user and subuser is created, however, when I try and generate a swift key for it, I get the following error:

 

radosgw-admin key create --subuser=testuser2:swift --key-type=swift --gen-secret

could not create key: unable to add access key, unable to store user info

2015-04-23 15:42:38.897090 7f38e157d820  0 WARNING: can't store user info, swift id () already mapped to another user (testuser2)

 

This suggests there is something wrong with the users or the configuration of the gateway somewhere.   Can someone provide some advice on what might be wrong, or where I can look to find out.   I have gone through whatever log files I can and don’t see anything of any use at the moment.

 

Any help appreciated.

 

Thanks

 

Alistair
