Hi, Can't add new host to ovirt engine, because the following error: 2019-06-12 12:23:09,664 p=4134 u=engine | TASK [ovirt-host-deploy-facts : Set facts] ************************************* 2019-06-12 12:23:09,684 p=4134 u=engine | ok: [10.35.1.17] => { "ansible_facts": { "ansible_python_interpreter": "/usr/bin/python2", "host_deploy_vdsm_version": "4.40.0" }, "changed": false } 2019-06-12 12:23:09,697 p=4134 u=engine | TASK [ovirt-provider-ovn-driver : Install ovs] ********************************* 2019-06-12 12:23:09,726 p=4134 u=engine | fatal: [10.35.1.17]: FAILED! => {} MSG: The conditional check 'cluster_switch == "ovs" or (ovn_central is defined and ovn_central | ipaddr and ovn_engine_cluster_version is version_compare('4.2', '>='))' failed.

Lightbits is a clustered storage system while upstream is a single target, but the client side should be close enough for vdsm/ovirt purposes. I played with NVMe/TCP a little bit, using qemu to create a virtual NVMe disk, and export it using the kernel on one VM, and consume it on another VM. https://futurewei-cloud.github.io/ARM-Datacenter/qemu/nvme-of-tcp-vms/ One question about device naming - do we always get the same name of the device in all hosts? To support VM migration, every device must have unique name in the cluster. With multipath we always have unique name, since we disable "friendly names", so we always have: /dev/mapper/{wwid} With rbd we also do not use /dev/rbdN but a unique path: /dev/rbd/poolname/volume-vol-id How do we ensure cluster-unique device path? If os_brick does not handle it, we can to do in ovirt, for example: /run/vdsm/mangedvolumes/{uuid} -> /dev/nvme7n42 but I think this should be handled in cinderlib, since openstack have the same problem with migration.

Re: [ovirt-users] Re: [=EXTERNAL=] Re: help using nvme/tcp storage with cinderlib and Managed Block Storage

by Benny Zlotnik

Switching to +devel Browsing the code a bit, I think a good starting point would be https://github.com/oVirt/vdsm/blob/500c035903dd35180d71c97791e0ce4356fb77... - if volume_type not in ("rbd", "iscsi"): + if volume_type not in ("rbd", "iscsi", "lightos"): And it's possible that it would be all that's required to make it work on ovirt >=4.5 https://github.com/oVirt/vdsm/blob/500c035903dd35180d71c97791e0ce4356fb77... The path resolver might warn, but it looks like it would return /dev/nvme0n so the generated udev rule should come out correct I'm happy to assist if it turns out to be more challenging (and if not) :)

ovirt-engine git repository is going to be moved to GitHub on Friday Feb 4th

by Martin Perina

Hi, We have solved the RPM build issue on github, so we are going to move ovirt-engine git repository from Gerrit <https://gerrit.ovirt.org/admin/repos/ovirt-engine> to GitHub <https://github.com/ovirt/ovirt-engine> this Friday Feb 4th. The mirroring from gerrit to github is going to be disabled at 14:00 CET and ovirt-engine repository on Gerrit <https://gerrit.ovirt.org/admin/repos/ovirt-engine> is going to be changed to read-only, so all open patches on gerrit will need to be converted to GitHub PRs by their owners. If you haven't worked with GitHub previously please check Working with oVirt on GitHub <https://www.ovirt.org/develop/dev-process/working-with-github.html>. Feel free to reply to this email if you have any additional questions or concerns. Thanks, Martin -- Martin Perina Manager, Software Engineering Red Hat Czech s.r.o.
