nttHi, I'm trying to install openstack-freezer in a mitaka environment but I have some errors in the dashboard. Someone can help me please?07:32

yangyapenghi ntt08:56
yangyapengntt:  :) what error08:58
nttyangyapeng: Unable to retrieve request id from context09:00
yangyapengwhether have some log about this.09:00
slashmeHi ntt09:00
slashmeI think m3m0 has a solution for this.09:01
slashmeSonething about static content not being copied if I remember well09:01
slashmeHe should be in our office shortly, I'll ask him09:01
nttok.... I don't know if I'll be online... anyway tomorrow I will come back.09:03
nttJust one question about cinder backups09:03
nttshould I install the agent and the scheduler on the openstack-cinder-volume machine or on the controller machine?09:03
ntt( I have 2 separate machine, one for openstack-cinder-api and openstack-cinder-scheduler and another for openstack-cinder-volume=09:04
ntt)09:04
yangyapengit is ok both . To ensure that the freezer can be connected to cinder09:05
yangyapengi have a freezer in a separate machine, and controller and cinder in another machine,09:06
nttand is there a way to minimize the traffic? I mean: the volume resides physically on the cinder-volume machine. Should It be copied over the controller and after on the swift backend?09:06
yangyapengyeah, cinder volume should backup to swift over swift and cinder or glance api.09:08
slashmeIf you want to minimize the traffic, then, you need your cinder, glance and freezer on the same node09:08
nttslashme: all components of cinder?09:08
slashmeWell, It depends...09:09
nttand furthermore: why glance? is glance involved on cinder backups if I use freezer?09:10
slashmeIf you plan on using *cindernative* (this way, freezer just orchestrate the cinder-backup api), then it does not matter that much. What does matter is how you configure your cinder-backup services.09:10
nttI think I cannot use cindernative because I have a separate swift environment with a separate keystone. Cinder-backups doesn't work because cinder uses another keystone and cannot share the token09:11
nttThink my environment as a mitaka cluster with all components except swift.09:11
nttIn my case swift is an external storage, completely detached from mitaka09:12
yangyapengcurrent, freezer depend on openstack keystone token to upload backup to swift09:15
nttand what if I install freezer-api and freezer-we-ui in the swift environment? Can I install agent and scheduler on a cinder node?09:17
*** electrofelix has joined #openstack-freezer09:19
slashmeIf you plan on using cinder (This way, freezer manages the backup, with this workflow: cinder snapshot => upload the snapshot to glance => download the snapshot and stream it to the freezer storage(swift, local or ssh)). Then you might want to colocate as many as you can of these services: cinder-volume glance-api swift freezer-agent and freezer-scheduler09:19
slashmeYou can install them wherever you want if you plan on doing Cindev/Nova backups. As long as they can reach the api's they need09:21

nttslashme: I cannot use this configuration09:29
nttAt this point, I think I can save cinder volumes doing an lvm snapshot .... if I corectly remember, freezer supports lvm snapshots09:30
slashmeYes it does.09:32
slashmeSo you want to backup the volume's file directly from the cinder node ?09:33
*** lpetrut has joined #openstack-freezer09:34
nttyes... I think it is the better solution. But it is not so simple.... because I can create a snapshot on cinder... but I cannot mount it (I think). On that volume in fact, there is not a filesystem09:35
yangyapengWhy not just backup cinder-volume to NFS09:37
nttbecause I have a SAN, I have swift, but I don't have a NAS09:38
yangyapengoh oh09:38
