| reicky | Hi guys. I'm currently trying to do NVMe-oF with cinder. So I installed openstack using devstack and I try to configure the SPDK driver of cinder. Is it possible with cinder to configure an SPDK target or is the driver "only" doing the initiator part? | 13:46 |
| *** ociuhandu has quit IRC | 13:47 | |
| reicky | I asked that because in cinder.conf we need to configure the NVMe-oF target IP address so I assume that the target must be created outside cinder but I'm not sure... | 13:49 |

| hemna | the spdk driver requires a target driver enabled as well | 13:57 |

| tosky | sfernand: hi! Have you seen the comment in https://review.opendev.org/c/openstack/cinder/+/764275/ ? | 14:03 |
| *** ociuhandu has quit IRC | 14:04 | |
| sfernand | Just seen that. Thanks. I will answer to Eric | 14:05 |
| sfernand | but basically we have been merging the solidfire history and versions since we don’t bump it every release | 14:06 |
| *** baojg has quit IRC | 14:07 | |
| sfernand | I know that is far from ideal | 14:07 |
| tosky | sfernand: I guess it's just a matter of clarifying that with eharney | 14:07 |
| sfernand | Yep | 14:07 |
| tosky | we have a pending train tag that's being pushed forward for too long, hence my interest in some of those patches :) | 14:07 |
| *** jv__ has joined #openstack-cinder | 14:07 | |
| *** jv_ has quit IRC | 14:07 | |
| eharney | the main point is that you don't want 2.2.2 in train to be very different from 2.2.2 in a newer branch | 14:08 |
| sfernand | Yes you are correct | 14:08 |
| eharney | better options are a) don't change the version number when backporting or b) bump it to something specific for that branch (2.0.18) | 14:08 |
| *** ociuhandu has joined #openstack-cinder | 14:10 | |
| reicky | hemna: thanks for the pointer. So if I understand correctly I need to configure my target manually (using SPDK JSON RPC for example) and then I will be able to use the target driver. Currently only RDMA can be used (no support for TCP). | 14:10 |
| *** ociuhandu has quit IRC | 14:15 | |
| sfernand | eharney: that makes sense I can change it to 2.0.18. | 14:16 |
| tosky | rosmaita: if you agree with that too, maybe we can speed this up :) | 14:17 |
| rosmaita | tosky: you mean about the version number change? | 14:17 |
| tosky | rosmaita: yes | 14:18 |
| reicky | Oh in fact by looking https://github.com/openstack/cinder/blob/master/cinder/volume/targets/spdknvmf.py it seems that SPDK target can be created by cinder. I guess that all configurations for spdknvmf and nvmeof drivers are done in cinder.conf (I'm new to openstack and cinder). | 14:19 |
| rosmaita | sfernand: 2.0.18 sounds good to me, the key thing is that you want a support to know whether they are using a fixed driver or not, and the version number bump is the easiest way to do that | 14:19 |
| sfernand | rosmaita: ok! | 14:25 |

| zigo | Hi there ! | 14:42 |
| zigo | In Debian Bullseye, we may not have cgroupv1, but only cgroupv2 available. | 14:42 |
| zigo | So I wonder if the Cinder team has thought about using io stuff as per this doc: https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html#io | 14:42 |
| *** knomura has quit IRC | 14:42 | |
| zigo | It comes to Debian first, as usual, though it's kind of clear that it's going to happen for other distro, sooner or later... | 14:43 |
| zigo | I of course would love to fix the cgroupv1 to v2 thing before Bullseye is out in a few months (I could backport some eventual patches to cinder/privsep/cgroup.py ...) | 14:44 |
| zigo | Your thoughts? | 14:44 |

| reicky | In https://docs.openstack.org/cinder/latest/configuration/block-storage/drivers/spdk-volume-driver.html there are some configuration for the SPDK NVMe-oF transport. Should it be put in a specific section of cinder.conf? I'm new to cinder and openstack and it is not clear to me. | 16:25 |
| reicky | Also can we have several volume_driver in cinder.conf ? Or if I'm using cinder.volume.drivers.spdk.SPDKDriver I should remove the volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver that is the default one for devstack (I'm using devstack for testing). | 16:27 |
| reicky | If you know some links (like blogs, video, presentation...) where someone describes the cinder configuration for SPDK NVMe-oF I take it :-). | 16:30 |
| tosky | reicky: you can have multiple drivers, and I suspect those options need to be set into the configuration section of the driver | 16:32 |
| tosky | and the documention... is our documentation: https://docs.openstack.org/cinder/latest/admin/blockstorage-multi-backend.html | 16:32 |
| *** __ministry has joined #openstack-cinder | 16:38 | |
| reicky | tosky: thanks. Oh if I understand correctly the name of the configuration section of a driver is "[its name]driver-1" because I don't find example with spdk. I missed that. I will try that. | 16:43 |
| reicky | And also it is not clear for me how the target-helper (like spdk-nvmeof) and the driver spdk are working together (if they do). Hope that with the correct configuration section for SPDK I will understand. | 16:49 |

| tosky | ceph support question: at the time of train release, the active ceph versions were nautilus, mimic and luminous, if I read this correctly: https://docs.ceph.com/en/latest/releases/general/#lifetime-of-stable-releases | 18:36 |
| tosky | does it mean that we support n, m, l, k, j for train, according the policy https://docs.openstack.org/cinder/latest/configuration/block-storage/drivers/ceph-rbd-volume-driver.html ? | 18:36 |
| tosky | but what if I want to enable a feature which works from mimic only also on train gates? devstack-plugin-ceph configures nautilus, so from the gates point of view that should be fine | 18:38 |
| tosky | and it wouldn't worse than what we have now | 18:39 |
| *** hemna has quit IRC | 18:39 | |
| tosky | I think? | 18:39 |
| tosky | but should then we add some additional jobs to test the older ceph releases? (this is a question for the newer releases as well) | 18:39 |

| *** hemna has joined #openstack-cinder | 19:26 | |
| rosmaita | tosky: was afk, thinking now | 19:32 |
| rosmaita | tosky: since ceph is on yearly releases, for 2019 (train is fall 2019), they supported M and N, so we would only support k,l,m,n for train ... except that our "support" statement wasn't announced until Wallaby development (Nov 2020) -- before that, we just supported Ceph | 20:03 |
| rosmaita | jere | 20:03 |
| rosmaita | here's what we discussed back in november about testing: http://eavesdrop.openstack.org/meetings/cinder/2020/cinder.2020-11-25-14.01.log.html#l-74 | 20:04 |
| rosmaita | but to answer your question about train testing, we tend to test with the latest ceph all the time, so for train that would be N, so i think that's ok | 20:05 |
| rosmaita | i'm not against testing with older versions of ceph, though i'd probably prefer a periodic job rather than do it in the check/gate | 20:05 |
| tosky | rosmaita: thanks, at least I know I can test a certain mimic feature | 20:22 |
| tosky | a feature you may have heard about | 20:22 |
