Re: radosgw-agent failed to parse

[<ghislain.chevalier@xxxxxxxxxx>]

HI all,

 

Context : Ubuntu 14.04 TLS firefly 0.80.7

 

I recently encountered the same issue as described below.

Maybe I missed something between July and January…

 

I found that the http request wasn't correctly built by /usr/lib/python2.7/dist-packages/radosgw_agent/client.py

 

I did the changes below

#    url = ''.format(protocol=request.protocol,

#                                             host=request.host,

#                                             path=request.path)

     url = ''.format(protocol="", host="", path=request.path)

 

The request is then correctly built and sent.

 

Best regards

hello again,

i have reviewed my deployment, and --name argument is used everywhere with radosgw-admin command.

as i create the pools during deploy, there is no rgw.root pool, so i cannot make changes to it.

I still think this is an issue with radosgw-agent, as if i change the destination on the command line, it also changes in the botched up URL it tries to hit:  "radosgw-agent http://example2.net" this appears in the error:

DEBUG:boto:url = ''

so it is definitely coming from input from command line.

You should use the --name argument with every radosgw-admin command.  If you don't, you'll end up making changes to .rgw.root, not .us.rgw.root.

 

I'd run through the federation setup again, making sure to include the appropriate --name.  As Kurt said, it's safe to reload and reapply the configs.  Make sure you restart radosgw when it says.  

 

One of my problems during setup was that I had a bad config loaded in .rgw.root, but the correct one in .us.rgw.root.  It caused all sorts of problems when I forgot the --name arg.

 

Setting up federation is somewhat sensitive to order of operations.  When I was testing it, I frequently messed something up.  Several times it was faster to delete all the pools and start over, rather than figuring out what I broke.

adding --name to regionmap update command has allowed me to update the regionmap:

radosgw-admin regionmap update --name client.radosgw.us-master-1

so now i have reloaded zone and region and updated region map on the gateway in each zone, then restarted whole clusters, then restarted apahce and radosgw, same problem.

I cannot see how this can be anything other than an issue inside radosgw-agent as it is not hitting the gateway due to the botched

DEBUG:boto:url = ''

Im out of ideas. Should i submit this as a bug?

It certainly doesn’t hurt to reload your zone and region configurations on your RGWs and re-run the regionmap update for the instances tied to each zone, just to ensure consistency.

thanks for the suggestion. ive attempted a regionmap update but im hitting this error:

failed to list regions: (2) No such file or directory
2014-07-22 14:13:04.096601 7ff825ac77c0 -1 failed to list objects pool_iterate_begin() returned r=-2

so perhaps i do have some issue with my configuration. Although i would have thought that if the gateway is outputting the correct regionmap at /admin/config path, then all should be well with regionmap.

I’m sure you’ve already tried this, but we’ve gotten burned a few times by not running radosgw-admin regionmap update after making region/zone changes.  Bouncing the RGW’s probably wouldn’t hurt either.

yes, im scratching my head over this too. It doesn't seem to be an authentication issue as the radosgw-agent never reaches the us-secondary gateway (i've kept an eye on us-secondary logs as i execute radosgw-agent on us-master).

On 22/07/14 03:51, Craig Lewis wrote:

I was hoping for some easy fixes :-P

 

I created two system users, in both zones.  Each user has different access and secret, but I copied the access and secret from the primary to the secondary.  I can't imaging that this would cause the problem you're seeing, but it is something different from the examples.

 

Sorry, I'm out of ideas.

hello again,

i couldn't find  'http://us-secondary.example.comhttp://us-secondary.example.com/' in any zone or regions config files. How could it be getting the URL from someplace else if i am specifying as command line option after radosgw-agent ?


Here is region config:

{ "name": "us",
  "api_name": "us",
  "is_master": "True",
  "endpoints": [
        "http:\/\/us-master.example.com:80\/"],

          "log_meta": "true",
          "log_data": "true"},
        { "name": "us-secondary",
          "endpoints": [
                "http:\/\/us-master.example.com:80\/"],

        ],
  "placement_targets": [
   {
     "name": "default-placement",
     "tags": []
   }
  ],
  "default_placement": "default-placement"}

I also get the above when i navigate to http://us-master.example.com/admin/config  and http://us-secondary.example.com/admin/config .

us-master zone looks like this:

{ "domain_root": ".us-master.domain.rgw",
  "control_pool": ".us-master.rgw.control",
  "gc_pool": ".us-master.rgw.gc",
  "log_pool": ".us-master.log",
  "intent_log_pool": ".us-master.intent-log",
  "usage_log_pool": ".us-master.usage",
  "user_keys_pool": ".us-master.users",
  "user_email_pool": ".us-master.users.email",

  "user_uid_pool": ".us-master.users.uid",
  "system_key": { "access_key": "EA02UO07DA8JJJX7ZIPJ", "secret_key": "InmPlbQhsj7dqYYYYjdNabqkZaqR8ShWC6fS0XVo"},
  "placement_pools": [
    { "key": "default-placement",
      "val": { "index_pool": ".us-master.rgw.buckets.index",
               "data_pool": ".us-master.rgw.buckets"}
    }
  ]
}

us-secondary zone:

{ "domain_root": ".us-secondary.domain.rgw",
  "control_pool": ".us-secondary.rgw.control",
  "gc_pool": ".us-secondary.rgw.gc",
  "log_pool": ".us-secondary.log",
  "intent_log_pool": ".us-secondary.intent-log",
  "usage_log_pool": ".us-secondary.usage",
  "user_keys_pool": ".us-secondary.users",
  "user_email_pool": ".us-secondary.users.email",
  "user_swift_pool": ".us-secondary.users.swift",
  "user_uid_pool": ".us-secondary.users.uid",
  "system_key": { "access_key": "EA02UO07DA8JJJX7ZIPJ", "secret_key": "InmPlbQhsj7dqYYYYjdNabqkZaqR8ShWC6fS0XVo"},

    { "key": "default-placement",
      "val": { "index_pool": ".us-secondary.rgw.buckets.index",
               "data_pool": ".us-secondary.rgw.buckets"}
    }
  ]
}

us-master user exists on us-master cluster gateway, us-secondary user exists on us-secondary cluster gateway. both us-master and us-secondary gateway users have same access and secret key. should us-master and us-secondary users exist on both clusters?

i can resolve us-master.example.com and us-secondary.example.com from both gateways.


Thanks

Just to ask a couple obvious questions...

 

You didn't accidentally put 'http://us-secondary.example.comhttp://us-secondary.example.com/' in any of your region or zone configuration files?  The fact that it's missing the :80 makes me think it's getting that URL from someplace that isn't the command line.

 

You do have both system users on both clusters, with the same access and secret keys?

 

You can resolve us-secondary.example.com. from this host?

 

 

I tested URLs of the form http://us-secondary.example.com/ and http://us-secondary.example.com:80 in my setup, and both work fine.

thank you for your reply. I am running ceph 0.80.1, radosgw-agent 1.2 on Ubuntu 14.04 LTS (GNU/Linux 3.13.0-24-generic x86_64) . I also ran into this same issue with ubuntu 12.04 previously.
There are no special characters in the access or secret key (ive had issues with this before so i make sure of this).

here is the output python interpreter:

us-secondary.example.com 80

that looks ok to me.

It seems like an issue with your environment. What version of
radosgw-agent and which distro is this running on?

Are there any special characters in the access or secret keys that
might need to be escaped on the command line?

|DEBUG:boto:url =""> 'http://us-secondary.example.comhttp://us-secondary.example.com/admin/config'||


|should the url be repeated like that?

No, and it's rather strange since it should be the url passed on the
command line, parsed, and with /admin/config added.

Could post the result of this run in a python interpreter:

import urlparse
result = urlparse.urlparse('http://us-secondary.example.com:80')
print result.hostname, result.port
