Tony31 | hi guys - could anyone help me get my head around the "all in one" kayobe approach? | 06:59 |
Tony31 | My problems are around the networking - what ever I try doesnt seem to work, or rather gets past the problem but then I find another | 06:59 |
Tony31 | my latest problem seems to be that the aio hypervisor/host can't route to the seed VM's IP because the host has real network and bridge network in the same subnet | 07:00 |
Tony31 | For example, my host VM has IP 192.168.1.100. So I have `seed_hv_ip=192.168.1.100`. If I then use 192.168.1.0/24 for the network allocations, this passes all the validations but I'm unable to access the seed VM once it's deployed | 07:04 |

mgoddard | yoctozepto: let's see how train wifi goes | 08:56 |
yoctozepto | mgoddard: crossing fingers | 08:56 |
Tony31 | kayobe guys - I have a couple of machines I built for machine learning, with multiple nvidia GPUs etc. . I am reading up the stackHPC website about ironic and managing hardware. I dont have the right nvidia GPUs to be able to virtualise them (example, run the bare metal as a host and run VMs on top, with pci pass-through). But I wanted to ask - | 08:58 |
Tony31 | could I manage this hardware from openstack and allow people to deploy and access the real hardware, then destroy when theyr'e done? | 08:58 |
Tony31 | basically, use the real hardware and gpu's like a VM? | 08:59 |
Tony31 | I guess I'd need to make a custom image with the drivers | 08:59 |
mgoddard | hi Tony31. Are you sure you can't use PCI passthrough? No sharing, just pass through the entire GPU to a VM | 09:01 |
openstackgerrit | Radosław Piliszek proposed openstack/kolla-ansible master: DNM: keepalived testing https://review.opendev.org/690920 | 09:01 |
mgoddard | otherwise, you could use ironic to make the bare metal available to users. In that case it's treated like a black box - the user can do (almost) what they like with the machine | 09:02 |
yoctozepto | Tony31: like mgoddard says, pci passtrough requires only vt-d in case of intel to work, no nvidia specific stuff nor sr-iov | 09:02 |
yoctozepto | (mentioning because some assume otherwise) | 09:03 |
yoctozepto | mgoddard: thx, I'll be backporting this to stable branches, at least train is nice as it affects upgrade jobs stability | 09:04 |
Tony31 | I have 3 x nvidia titan XP in each system - I was told that they wont work for virtualisation o_0 - but it would be better using them in Openstack I think anyway | 09:04 |
yoctozepto | Tony31: it depends on platform/mobo, not gpu | 09:05 |
mgoddard | yoctozepto: ok. Let's try to land the original patch and follow up together | 09:05 |
yoctozepto | any pci device can go passthrough | 09:05 |
yoctozepto | mgoddard: yes, indeed | 09:05 |
Tony31 | the system can be virtualised. I'll need to have a play with it - thanks for the info :) | 09:05 |
Tony31 | it's dual xeon, tons of RAM, trying to find info on the motherboard | 09:07 |
yoctozepto | Tony31: look up vt-d, dmar and iommu in google | 09:07 |
yoctozepto | it generally needs to be enabled in bios setup and then linux kernel | 09:07 |
Tony31 | thank you for that info | 09:09 |

theZorro266 | Hello, couldn't find a solution with some searches: I have been following https://docs.openstack.org/kolla-ansible/train/reference/storage/external-ceph-guide.html after using ceph-ansible as I understand ceph deployment by kolla-ansible is deprecated. I am running into the error "MissingRequiredSource: /var/lib/kolla/config_files/ceph.* file is not found" although the files exist in | 13:40 |
theZorro266 | "/etc/kolla/config/glance/". Is this a user error? The guide tells me nothing about permissions, so I assumed it should be fine with the same permissions as "/etc/kolla/glance-api/". | 13:40 |
kplant | what services are you using ceph for? | 13:43 |
kplant | and did you include both ceph.conf and the ceph keyrings? | 13:43 |
theZorro266 | I would like to use ceph for glance, cinder, nova, gnocchi and manila. I am generating keys for all of these services and the keys are in the appropiate directories as written in the linked guide | 13:44 |
*** rlljorge has joined #openstack-kolla | 13:44 | |
theZorro266 | And yeah, both ceph.client.glance.keyring and ceph.conf are in /etc/kolla/config/glance/ | 13:44 |
theZorro266 | but not in /etc/kolla/glance-api/ | 13:45 |
yoctozepto | mnasiadka: I will | 13:45 |
theZorro266 | and I understood that they should be merged into /etc/kolla/glance-api/ | 13:45 |
kplant | this is what mine looks like: https://pastebin.com/hSDusB7v | 13:46 |
theZorro266 | this is what it looks like over here: https://pastebin.com/iyghGxnM | 13:49 |
theZorro266 | Which version of kolla-ansible are you using? I see things have changed regarding glance external ceph setup between 9.0.1 and master | 13:51 |
kplant | stable/stein and stable/train | 13:51 |
kplant | so | 13:52 |
kplant | your permissions are 0660 | 13:52 |
kplant | what user are you running ansible as? | 13:52 |
kplant | if it's not root or in the root group it won't read them | 13:53 |
theZorro266 | I see. I run ansible as a user, of course | 13:53 |
theZorro266 | That is what I was asking above. I assumed /etc/kolla/glance-api/ should have the same permissions as in /etc/kolla/config/glance | 13:54 |
kplant | if you o+r on ceph.* you should be good | 13:55 |
theZorro266 | Yeah, not forgetting the directories, thank you! :) I'll try and see if that works | 13:57 |
*** reph has quit IRC | 14:07 | |
theZorro266 | It seems to work now, thanks again kplant :) This seems related to the "with_fileglob" in roles/glance/tasks/external_ceph.yml, because the list of files is obviously gathered as the user running ansible. This would mean only the folders in /etc/kolla/config should be world-readable/listable and not the keyrings/configs. Shouldn't this be in the docs? I could make a PR, but I'd need a hint | 14:14 |
theZorro266 | where to insert it to. | 14:14 |
theZorro266 | strike that. It copies the files, so it needs read access to the files as well | 14:15 |
kplant | ^ | 14:15 |
theZorro266 | but still, it would be better to have the files user-owned by the user running Ansible in that case | 14:16 |
kplant | i think that's in the quickstart | 14:16 |
theZorro266 | thats only the /etc/kolla directory | 14:17 |
theZorro266 | and all files within are being created and owned by root:root with zero permissions for world | 14:18 |
theZorro266 | that's where it misled me | 14:18 |
*** Luzi has quit IRC | 14:22 | |
theZorro266 | the external ceph guide is the first time I came into contact with the /etc/kolla/config directory, so any other place with that info should at least be linked from there in my understanding | 14:23 |

rlljorge | Hello @kplant in the last week we talk about the bug https://bugs.launchpad.net/kolla-ansible/+bug/1860739 Do you can share your kolla_base_distro with me ? | 18:41 |
openstack | Launchpad bug 1860739 in OpenStack Compute (nova) "Cinder backup failed for restore volume snapshot (for instance snapshot)" [Undecided,Confirmed] | 18:41 |
yoctozepto | oncall-pokemon, yankcrime, rlljorge, kplant: just to clarify - scaling mariadb galera cluster up *is* supported | 18:46 |
yoctozepto | scaling down is kinda too, it just involves a manual step of stopping extra mariadb when cluster is healthy with all the other member | 18:47 |
yoctozepto | s alive | 18:47 |
yoctozepto | (premature enter) | 18:47 |
rlljorge | yoctozepto nice ! thanks | 18:48 |

yoctozepto | mnasiadka: is that keystone fix ready to merge or you really expected a failure? | 19:50 |
mnasiadka | yoctozepto: well, it seems to work - was really just sarcastic :) | 19:53 |
mnasiadka | yoctozepto: I tested it also on scale out | 19:54 |
yoctozepto | mnasiadka: very well! | 19:54 |
mnasiadka | Which brings an observation - wouldn’t we want to have a periodic scale out job? | 19:54 |
mnasiadka | It is probably something our users sometimes do... or not | 19:55 |

yoctozepto | mnasiadka: makes sense, add it to scenarios | 20:17 |
yoctozepto | 1->3 scale obviously :-) | 20:17 |
*** jonaspaulo has joined #openstack-kolla | 20:17 | |
mnasiadka | yoctozepto: yeah, 3 to 5 is rather an overkill :) | 20:20 |
yoctozepto | mnasiadka: well, it tests if an existing multi does not get killed | 20:24 |
yoctozepto | we *might* want to have it running | 20:24 |
yoctozepto | but daily is an overkill | 20:24 |
yoctozepto | especially if you overdo the enabled services | 20:24 |
mnasiadka | yoctozepto: yeah, maybe weekly makes sense - 1->3->5 - it will probably fail multiple times :) I can start with 1->3 and lets see how that works | 20:27 |
yoctozepto | mnasiadka: it must not fail, we fixed a lot | 20:28 |
yoctozepto | mnasiadka: only haproxy/keepalived remains | 20:28 |
*** gfidente has quit IRC | 20:28 | |
yoctozepto | mnasiadka: I restored my machinery to play with it | 20:28 |
yoctozepto | mnasiadka: hoping to get it fixed too | 20:28 |
yoctozepto | mnasiadka: then we are golden like them kings 8-) | 20:29 |
mnasiadka | yoctozepto: it would be good to understand why it fails, and how to make it better | 20:29 |
yoctozepto | mnasiadka: that's the goal | 20:29 |
mnasiadka | yoctozepto: if we are in keepalived dept - would be good to document a procedure of maintenance failover :) | 20:29 |
* yoctozepto not listening | 20:30 | |
mnasiadka | Haha | 20:30 |
