| trinaths1 | one doubt doesn freezer-agent mandatory requires freezer-scheduler running? I'm trying freezer-agent in manual mode. | 10:52 |
| daemontool | trinaths1, nope, you can use it directly | 10:53 |
| trinaths1 | daemontool: right. | 10:53 |

| jiaopengju | trinaths1: what version do you use? | 10:54 |
| trinaths1 | jiaopengju: newton | 10:54 |
| daemontool | I think that is the log file of paramiko... | 10:55 |
| trinaths1 | daemontool: no. its the /root/.freezer/freezer-agent.log | 10:56 |

| daemontool | ok thanks | 10:59 |
| jiaopengju | trinaths1: and it works? | 10:59 |
| trinaths1 | still errors: http://paste.openstack.org/show/616696/ | 11:00 |

| trinaths1 | http://paste.openstack.org/show/616697/ | 11:01 |
| jiaopengju | trinaths1: if you use freezer-agent, it's no need to see the log of freezer-api | 11:02 |
| daemontool | I think this is the the following line in paramiko that is generating the error | 11:02 |

| *** Arianrhod has joined #openstack-freezer | 11:02 | |
| trinaths1 | daemontool: its a logger bug ? | 11:03 |
| daemontool | I'm not sure if it uses a different file or the same logging file used by freezer | 11:03 |
| daemontool | so what happen if you pass explicitely the log absolute path to the freezer-agent | 11:04 |
| trinaths1 | daemontool: will try now | 11:04 |
| trinaths1 | daemontool: its the same kind of error. http://paste.openstack.org/show/616700/ but this time freezer-api.log is not populated. | 11:06 |
| trinaths1 | do I need any conf file for agent ? | 11:06 |
| *** vnogin has joined #openstack-freezer | 11:06 | |
| daemontool | trinaths1, if I remember well, you can use a config file for agent but it's not required | 11:07 |
| trinaths1 | daemontool: okay. | 11:07 |
| daemontool | let me think, I'm not sure | 11:07 |
| trinaths1 | daemontool: when I did not give --log-file option, the agent log got populated. when I have given --log-file option, the agent log did not get populated. | 11:08 |
| daemontool | ok | 11:08 |
| daemontool | you have space in the ssh node right? | 11:09 |
| trinaths1 | yes 1 TB | 11:09 |

| trinaths1 | jiaopengju: yes. I see a mail in ML | 11:17 |

| trinaths1 | daemontool: but for me --no-incremental too didnot work well. | 13:27 |

| trinaths1 | daemontool: did u try restore ? | 13:28 |
| daemontool | not yet | 13:28 |
| trinaths1 | daemontool: ok | 13:31 |
| trinaths1 | daemontool: can you share the localrc for multi node devstack with freezer | 13:40 |
| daemontool | the multi node should not change in localrc | 13:43 |
| daemontool | you mean supporting multuiple backends to store backups? | 13:43 |
| trinaths1 | daemontool: nope | 13:43 |
| daemontool | ah ok you are looking for a localrc for a devstack deployed on multiple nodes? | 13:44 |
| trinaths1 | daemontool: I have installed installed devstack ocata controller. not in another compute node I want to know the localrc changes required for freezer for devstack compute node. | 13:44 |
| trinaths1 | daemontool: yes | 13:44 |
| daemontool | trinaths1, ok, I don't have it currently, sorry, I use a deploymend of openstack rh osp in the lab | 13:47 |
| daemontool | I assume you need that | 13:48 |
| daemontool | to automate the deployment of freezer during devstack install? | 13:48 |
| trinaths1 | daemontool: yes. I need to know how cinder and freezer are configured in localrc of devstack while installing a devstack compute node. | 13:51 |
| daemontool | ok, this doesn't help at all? https://github.com/openstack/freezer/tree/master/devstack | 13:51 |
| *** vnogin has quit IRC | 13:52 | |

| trinaths1 | https://docs.openstack.org/devstack/latest/guides/multinode-lab.html#configure-compute-nodes | 13:52 |
| trinaths1 | daemontool: at the compute-node config, https://docs.openstack.org/devstack/latest/guides/multinode-lab.html#configure-compute-nodes can I enable freezer as I did it in controller? I think freezer-api must not run there | 13:54 |
| daemontool | nope, freezer-api runs on controllers only | 13:55 |
| trinaths1 | daemontool: agree | 13:59 |
| daemontool | but you still want to install freezer agent there probably | 13:59 |
| trinaths1 | daemontool: true said. the how to enable cinder and freezer-scheduler and freezer-agent in devstack compute node ? | 13:59 |
| daemontool | why you need to enable cinder on the compute node? | 14:00 |
| daemontool | for freezer I think if you add the following it should work | 14:00 |
| daemontool | enable_plugin freezer https://git.openstack.org/openstack/freezer newton | 14:00 |
| daemontool | in [[local|localrc]] section of your local.conf | 14:01 |
| daemontool | the cinder dependencies neede for Nova on compute are deployed when installing nova | 14:01 |
| *** vnogin has joined #openstack-freezer | 14:01 | |
| daemontool | not sure why cinder would be needed explicitely on computes | 14:02 |
| trinaths1 | daemontool: that makes sense. okay | 14:02 |
| trinaths1 | daemontool: agree | 14:02 |
| jiaopengju | vnogin: do we have meeting today? | 14:05 |
| trinaths1 | daemontool: today we have freezer weekly meeting | 14:05 |
| vnogin | jiaopengju: I'm not sure. It seems that szaher on PTO | 14:06 |
| jiaopengju | vnogin: I know that. Thanks | 14:07 |
| trinaths1 | ok | 14:07 |
| daemontool | mhhh there's no topic change there | 14:07 |
| daemontool | in #openstack-meeting-alt | 14:08 |
| trinaths1 | daemontool: yes. | 14:10 |
| daemontool | trinaths1, use the ocata version of freezer | 14:10 |
| daemontool | even if you are on a newton openstack | 14:10 |
| daemontool | these issues are not present there | 14:10 |
| daemontool | it works correctly both backup and restore | 14:11 |
| trinaths1 | daemontool: yes doing the same now. moving to Ocata controller and compute | 14:11 |
| daemontool | anyway my feeling is that incrementals for ssh doesn't work | 14:12 |
| daemontool | I think the meetings have been suspended | 14:13 |
| daemontool | otherwise in the meeting room the topic would have changed already | 14:13 |
| daemontool | not sure | 14:13 |
| trinaths1 | daemontool: okay. since PTL is on leave this might have happened. | 14:14 |
| trinaths1 | daemontool: okay. thank you for the help. i'm now leaving for home its already 20:00 hr at office. | 14:14 |
| daemontool | yw | 14:14 |
| daemontool | bye | 14:15 |
| trinaths1 | daemontool: bye | 14:15 |
| *** trinaths1 has left #openstack-freezer | 14:15 | |
| daemontool | Ocata works quite well... but ssh backups on newton are broken | 14:16 |
| daemontool | rsync also works | 14:19 |
| daemontool | in Ocata including incrementals on ssh | 14:19 |
| daemontool | even tar, but the current level is not updated in the printout | 14:19 |
