perfSONAR User Q&A and Other Discussion

[Ryan Hitch <>]

I also have one client entry that has (2) lookup-service registrations (one by IP and another by hostname):

[user@dash]/usr/lib/perfsonar/bin/lookup_hosts --input /etc/perfsonar/meshconfig-lookuphosts.conf --output /var/www/html/dynamic_host_list.json

Resulting mesh is invalid: Multiple hosts match pas05.perf.sonar at /usr/lib/perfsonar/bin/../lib/perfSONAR_PS/MeshConfig/Config/Mesh.pm line 58.

One of these entries has an expiration date several days ago, but for some reason has not been cleaned out of the look-service database:

[user@dash lib]# perl query.pl
$VAR1 = bless( {
                 'RECORD_HASH' => {
                                    'group-domains' => [
                                                         'perf.sonar'
                                                       ],
                                    'ttl' => [],
                                    'interface-capacity' => [
                                                              '1000000000'
                                                            ],
                                    'interface-mac' => [
                                                         '20:47:37:5F:5F:DC'
                                                       ],
                                    'interface-mtu' => [
                                                         '1500'
                                                       ],
                                    'client-uuid' => [
                                                       '421d374f-1045-49e1-92ef-c03904e04e45'
                                                     ],
                                    'state' => 'renewed',
                                    'uri' => 'lookup/interface/665e4963-4ded-437a-ad27-5f7e35c5d176',
                                    'interface-name' => [
                                                          'em1'
                                                        ],
                                    'type' => [
                                                'interface'
                                              ],
                                    'interface-addresses' => [
                                                               '192.168.188.5'
                                                             ],
                                    'expires' => '2016-04-20T17:59:58.806Z'
                                  }
               }, 'SimpleLookupService::Records::Network::Interface' );

How can I remove these duplicate registrations and stale entries?

Any help is greatly appreciated.

Thanks!

Hi,

 

I am setting up a dynamic mesh with a private lookup service (which is also running Maddash and CMA).

Some of my clients register with this server using their IP address versus hostname, and I occasionally get clients registered twice.

For example, I see 192.168.188.5 and its hostname (ps5.node.sonar) when I do:

curl -v -H "Content-Type: application/js" -X GET http://localhost:8090/lookup/records/?type=service

These also show up as both hostname and IP in Maddash.

 

How can I get nodes to register consistently by hostname?

How can I remove the IP entries from my private lookup server?

 

Thanks!
