[manila]NFS-Ganesha exports
by Mikhail Okhrimenko 07 Apr '25

Hello community, Trying to setup the Manila version of Caracal with NFS-Ganesha backend. Ganesha version 4.0 is deployed using ceph orch in a ceph cluster version 17. Backend configuration in manila.conf [ganesha_nfs] driver_handles_share_servers = False share_backend_name = ganesha_nfs Share_driver = manila.share.drivers.cephfs.driver.CephFSDriver cephfs_protocol_helper_type = NFS cephfs_conf_path = /etc/ceph/ceph.conf cephfs_auth_id = manila cephfs_cluster_name = ceph cephfs_filesystem_name = {{ cephfs_filesystem_name }} cephfs_nfs_cluster_id = {{ cephfs_nfs_cluster_id }} I see the subvolume being created in ceph ceph fs subvolume ls <volume_name> but no export ceph nfs export ls <cluster_id> what am I doing wrong? what am I missing? in the manila-share logs I see a request to create a subvolume, but I don't see a request to create an export, for some reason manila doesn't even try to create an export

[blazar] Blazar-dashboard contains non-free files (ie: minified Javascripts)
by Thomas Goirand 05 Apr '25

05 Apr '25

Hi, I've been trying to package Blazar, all is already in Debian, but I can't get blazar-dashboard in, because upstream source contains non-free files. Namely: https://github.com/openstack/blazar-dashboard/blob/master/blazar_dashboard/… is a minifed version of a much more complex package: https://github.com/apexcharts/apexcharts.js/tree/v3.31.0 Reminder: minified Javascripts are considered by most distributions (this includes Red Hat, Ubuntu, and in my case Debian) as non-free files that cannot be shipped in the distribution without the underlying source code, and packages must build from the not minified version. Could the Blazar team work on un-vendoring apexcharts.min.js, possibly removing it completely, or replacing it with a source-full version? Cheers, Thomas Goirand (zigo)

[nova] vGPU not attached to VM using Cyborg with OpenStack Caracal
by ts.jung＠okestro.com 04 Apr '25

04 Apr '25

Hello, I'm facing an issue with vGPU assignment through Cyborg in OpenStack Caracal. Although Cyborg reports that the ARQ is bound successfully, the vGPU device is not attached to the VM in Nova. - Environment: OS: Ubuntu 22.04.3 LTS Kernel: 5.15.0-78-generic Nova API: 29.2.0 Cyborg API: 14.1.0.dev1 GPU: NVIDIA A100 PCIe 40GB - Device Profile: openstack accelerator device profile list +--------------------------------------+------+-----------------------------------------------------------------------------+ | uuid | name | groups | +--------------------------------------+------+-----------------------------------------------------------------------------+ | 8425925f-7a3c-4336-8a1c-270f481a28ae | vgpu | [{'resources:VGPU': '1', 'trait:CUSTOM_NVIDIA_20F1_A100_1_5C': 'required'}] | +--------------------------------------+------+-----------------------------------------------------------------------------+ Flavor: openstack flavor show vgpu --column properties +------------+-----------------------------+ | Field | Value | +------------+-----------------------------+ | properties | accel:device_profile='vgpu' | +------------+-----------------------------+ Result After VM Creation: openstack accelerator arq list +--------------------------------------+------+-----------------------------------------------------------------------------+ | uuid | name | groups | +--------------------------------------+------+-----------------------------------------------------------------------------+ | 8425925f-7a3c-4336-8a1c-270f481a28ae | vgpu | [{'resources:VGPU': '1', 'trait:CUSTOM_NVIDIA_20F1_A100_1_5C': 'required'}] | +--------------------------------------+------+-----------------------------------------------------------------------------+ ARQ shows Bound with an attach_handle_type of MDEV, but the GPU device is not visible inside the VM. mdevctl list # Shows UUID and mdev type virsh dumpxml instance-xxxx # No mdev device listed Logs (Summary) Cyborg logs indicate ARQ binding was successful and attach handle allocated (MDEV). Nova-compute logs show: Ignoring accelerator requests for instance ... Supported Attach handle types: {'PCI'}. But got these unsupported types: {'MDEV'}. Question. Is there something I’m missing in the integration between Cyborg and Nova for MDEV attach_handle_type? It seems like Nova is not yet supporting MDEV, even though Cyborg bound the ARQ correctly. Any suggestions or known workarounds would be appreciated. Thank you!

[Octavia] Active/Standby with AZ
by Vincent Godin 04 Apr '25

04 Apr '25

Hello, To address the Octavia and Cinder backend mismatch, I'm going to temporarily create a Cinder backend stretched across all three AZs. Now I have another question: is it possible to use Octavia AZs to set up an active/standby load balancer so that the active load balancer is on one AZ and the standby load balancer is on another one ? Of course, the network is stretched across all three AZs, so the VRRP mechanism is possible. Vincent

Hey I've been struggling with trying to get my kolla-ansible openstack multinode deployment working with my external trunked port i have openstack connected to and also using my external dhcp server. Does anyone have any thoughts on what I could be missing? I grasping at straws at this point and ill buy ya dinner if you can help me! when I launch a vm i see it assigning vms an ip but its no way its coming from my external dhcp server i think its just coming from its own pools. Also to add I'm using 2024.2 My global yaml - enable_neutron_provider_networks: "yes" neutron_external_interface: "bond0" network_interface: "eno3" when running ip a i see which i have no clue if they are suppose to say down in my head it doesn't seem right but im not sure because i havent had a successful deployment yet so not sure what its suppose to look like. bond0 <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovs-system state UP group default qlen 1000 ovs-system ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 br-ex: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 br-tun: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 extra conf files /etc/kolla/config/neutron/ml2_conf.ini [ml2] type_drivers = vlan tenant_network_types = vlan mechanism_drivers = openvswitch extension_drivers = port_security [ml2_type_vlan] network_vlan_ranges = physnet1:100:100,physnet1:144:144,physnet1:513:513 /etc/kolla/config/neutron/openvswitch_agent.ini [ovs] bridge_mappings = physnet1:br-ex Thanks, Jonathan Bowley IT Specialist / DevOps Engineer / SysAdmin IT Services National Geospatial Technical Operations Center (NGTOC<http://ngtoc.usgs.gov/>) U.S. Geological Survey Rolla, Missouri

Non predictable device name/path in libvirt/qemu config with multipath
by Gilles Mocellin 04 Apr '25

04 Apr '25

Hello Stackers, Today I had a stressful problem. While doing system upgrades on my Ubuntu based OpenStask-Ansible deployment, with Pure Storage cinder driver and boot from volume instances, I faced that problem : While migrating instances to evacuate a compute node, several instances never wanted to live migrate (Kubernetes workers with 16GB RAM). After restarting several times, attempting to change some nova/libvirt configuration (certainly not taken, because qemu was not restarted on source host), I decider to cold migrate thoses instances. So I simply use : openstack server migrate instance-uuid The instances tried to start on other compute node, but failed. Two have the same problem I would talk about, the third just didn't find the volume/LUN on the storage Array (also very weird). So, why the other two didn't start ? They wanted to use a multipath map that was already in use. And really in use from another instance. the multipath -f mpathxy was tried and make the multipath map unusable for the instance which used it. It was the database of an important app, to add a little bit of stress. This is not happening with successful live migration, I only see it with cold migrations. But with some instances, I really don't manage to have a successful live migration, so it can be useful to also have a working cold migration (I mean stop, migrate, and start the instance). So, my questions are : 1. Should multipath.conf enable or not user friendly names ? I didn't find a recommended multipath config. I saw both in kolla templates (not using friendly names) or starlingX ones or old bugs (using friendly names, for data flush to really be effective on paths...) Didn't find yet if openstack-ansible is managing multipath or not. I would say that without friendly names, we have predictable names in /dev/ mapper/ (with WWN), that if used couldn't lead to device "steal" if every instance record that predictable device. 2. Is there some configuration for libvirt/qemu ? Because, in the libvirt/qemu instance config file, the devices are not the multipath map but the /dev/dm-XY where the multipath map symlinks to... Also not predictable and changing, especially when changing compute hosts with different number of accessible volumes... Did someone already had those problems, and how do you handled it ?
