deprecating export domain?
by Charles Kozler 30 Aug '20

30 Aug '20

Hello, I recently read on this list from a redhat member that export domain is either being deprecated or looking at being deprecated To that end, can you share details? Can you share any notes/postings/bz's that document this? I would imagine something like this would be discussed in larger audience This seems like a somewhat significant change to make and I am curious where this is scheduled? Currently, a lot of my backups rely explicitly on an export domain for online snapshots, so I'd like to plan accordingly Thanks!

Hi Leo, As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes. You can use the following for adding the bricks: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html/Admi… Best Regards, Strahil NikolivOn May 26, 2019 10:54, Leo David <leoalex(a)gmail.com> wrote: > > Hi Stahil, > Thank you so much for yout input ! > > gluster volume info > > > Volume Name: engine > Type: Distribute > Volume ID: d7449fc2-cc35-4f80-a776-68e4a3dbd7e1 > Status: Started > Snapshot Count: 0 > Number of Bricks: 1 > Transport-type: tcp > Bricks: > Brick1: 192.168.80.191:/gluster_bricks/engine/engine > Options Reconfigured: > nfs.disable: on > transport.address-family: inet > storage.owner-uid: 36 > storage.owner-gid: 36 > features.shard: on > performance.low-prio-threads: 32 > performance.strict-o-direct: off > network.remote-dio: off > network.ping-timeout: 30 > user.cifs: off > performance.quick-read: off > performance.read-ahead: off > performance.io-cache: off > cluster.eager-lock: enable > Volume Name: ssd-samsung > Type: Distribute > Volume ID: 76576cc6-220b-4651-952d-99846178a19e > Status: Started > Snapshot Count: 0 > Number of Bricks: 1 > Transport-type: tcp > Bricks: > Brick1: 192.168.80.191:/gluster_bricks/sdc/data > Options Reconfigured: > cluster.eager-lock: enable > performance.io-cache: off > performance.read-ahead: off > performance.quick-read: off > user.cifs: off > network.ping-timeout: 30 > network.remote-dio: off > performance.strict-o-direct: on > performance.low-prio-threads: 32 > features.shard: on > storage.owner-gid: 36 > storage.owner-uid: 36 > transport.address-family: inet > nfs.disable: on > > The other two hosts will be 192.168.80.192/193 - this is gluster dedicated network over 10GB sfp+ switch. > - host 2 wil have identical harware configuration with host 1 ( each disk is actually a raid0 array ) > - host 3 has: > - 1 ssd for OS > - 1 ssd - for adding to engine volume in a full replica 3 > - 2 ssd's in a raid 1 array to be added as arbiter for the data volume ( ssd-samsung ) > So the plan is to have "engine" scaled in a full replica 3, and "ssd-samsung" scalled in a replica 3 arbitrated. > > > > > On Sun, May 26, 2019 at 10:34 AM Strahil <hunter86_bg(a)yahoo.com> wrote: >> >> Hi Leo, >> >> Gluster is quite smart, but in order to provide any hints , can you provide output of 'gluster volume info <glustervol>'. >> If you have 2 more systems , keep in mind that it is best to mirror the storage on the second replica (2 disks on 1 machine -> 2 disks on the new machine), while for the arbiter this is not neccessary. >> >> What is your network and NICs ?

Failed to add storage domain

Hi! I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.

How to connect to a guest with vGPU ?
by Josep Manel Andrés Moscardó 29 May '20

29 May '20

Hi, I got vGPU through mdev working but I am wondering how I would connect to the client and make use of the GPU. So far I try to access the console through SPICE and at some point in the boot process it switches to GPU and I cannot see anything else. Thanks. -- Josep Manel Andrés Moscardó Systems Engineer, IT Operations EMBL Heidelberg T +49 6221 387-8394

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero 18 Feb '20

18 Feb '20

Hi all, Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month. The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems. The vm runs without problems after unpausing it.

Ovirt-engine-ha cannot to see live status of Hosted Engine
by asm＠pioner.kz 01 Feb '20

Good day for all. I have some issues with Ovirt 4.2.6. But now the main this of it: I have two Centos 7 Nodes with same config and last Ovirt 4.2.6 with Hostedengine with disk on NFS storage. Also some of virtual machines working good. But, when HostedEngine running on one node (srv02.local) everything is fine. After migrating to another node (srv00.local), i see that agent cannot to check livelinness of HostedEngine. After few minutes HostedEngine going to reboot and after some time i see some situation. After migration to another node (srv00.local) all looks OK. hosted-engine --vm-status commang when HosterEngine on srv00 node: --== Host 1 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : srv02.local Host ID : 1 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down_unexpected", "detail": "unknown"} Score : 0 stopped : False Local maintenance : False crc32 : ecc7ad2d local_conf_timestamp : 78328 Host timestamp : 78328 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=78328 (Tue Sep 18 12:44:18 2018) host-id=1 score=0 vm_conf_refresh_time=78328 (Tue Sep 18 12:44:18 2018) conf_on_shared_storage=True maintenance=False state=EngineUnexpectedlyDown stopped=False timeout=Fri Jan 2 03:49:58 1970 --== Host 2 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : srv00.local Host ID : 2 Engine status : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : 1d62b106 local_conf_timestamp : 326288 Host timestamp : 326288 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=326288 (Tue Sep 18 12:44:21 2018) host-id=2 score=3400 vm_conf_refresh_time=326288 (Tue Sep 18 12:44:21 2018) conf_on_shared_storage=True maintenance=False state=EngineStarting stopped=False Log agent.log from srv00.local: MainThread::INFO::2018-09-18 12:40:51,749::states::779::ovirt_hosted_engine_ha.agent.hosted_engine.HostedE ngine::(consume) VM is powering up..

But, installation was unsuccesfull, before i didnt install ovirt-hosted-engine-ha on this node. I dont see in documentation that its need bofore installation of new hosts. But this is for information and checking. After installing ovirt-hosted-engine-ha node was installed with HostedEngine support. But the main issue not changed. Thanks in advance for help.

Hyperconverged setup - storage architecture - scaling
by Leo David 10 Jan '20

10 Jan '20

Hello Everyone, Reading through the document: "Red Hat Hyperconverged Infrastructure for Virtualization 1.5 Automating RHHI for Virtualization deployment" Regarding storage scaling, i see the following statements: *2.7. SCALINGRed Hat Hyperconverged Infrastructure for Virtualization is supported for one node, and for clusters of 3, 6, 9, and 12 nodes.The initial deployment is either 1 or 3 nodes.There are two supported methods of horizontally scaling Red Hat Hyperconverged Infrastructure for Virtualization:* *1 Add new hyperconverged nodes to the cluster, in sets of three, up to the maximum of 12 hyperconverged nodes.* *2 Create new Gluster volumes using new disks on existing hyperconverged nodes.You cannot create a volume that spans more than 3 nodes, or expand an existing volume so that it spans across more than 3 nodes at a time* *2.9.1. Prerequisites for geo-replicationBe aware of the following requirements and limitations when configuring geo-replication:One geo-replicated volume onlyRed Hat Hyperconverged Infrastructure for Virtualization (RHHI for Virtualization) supports only one geo-replicated volume. Red Hat recommends backing up the volume that stores the data of your virtual machines, as this is usually contains the most valuable data.* ------ Also in oVirtEngine UI, when I add a brick to an existing volume i get the following warning: *"Expanding gluster volume in a hyper-converged setup is not recommended as it could lead to degraded performance. To expand storage for cluster, it is advised to add additional gluster volumes." * Those things are raising a couple of questions that maybe for some for you guys are easy to answer, but for me it creates a bit of confusion... I am also referring to RedHat product documentation, because I treat oVirt as production-ready as RHHI is. *1*. Is there any reason for not going to distributed-replicated volumes ( ie: spread one volume across 6,9, or 12 nodes ) ? - ie: is recomanded that in a 9 nodes scenario I should have 3 separated volumes, but how should I deal with the folowing question *2.* If only one geo-replicated volume can be configured, how should I deal with 2nd and 3rd volume replication for disaster recovery *3.* If the limit of hosts per datacenter is 250, then (in theory ) the recomended way in reaching this treshold would be to create 20 separated oVirt logical clusters with 12 nodes per each ( and datacenter managed from one ha-engine ) ? *4.* In present, I have the folowing one 9 nodes cluster , all hosts contributing with 2 disks each to a single replica 3 distributed replicated volume. They where added to the volume in the following order: node1 - disk1 node2 - disk1 ...... node9 - disk1 node1 - disk2 node2 - disk2 ...... node9 - disk2 At the moment, the volume is arbitrated, but I intend to go for full distributed replica 3. Is this a bad setup ? Why ? It oviously brakes the redhat recommended rules... Is there anyone so kind to discuss on these things ? Thank you very much !

I got a error in webui: VDSM ovirt1.ntbaobei.com command HSMGetAllTasksStatusesVDS failed: Volume Group not big enough: (u'Not enough free extents for extending LV d9f2378f-92f0-4bc1-96a8-20a0f2c575cb/c515a3f9-0590-4ebe-81c5-9d0993f1fec9 (free=848, needed=872)',) seems no enough space in the storage domain.

by Dev Ops 18 Sep '19

18 Sep '19

I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server. A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts. I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help. [root@blah-lab-engine ~]# engine-config -a |grep Upload UploadImageChunkSizeKB: 10240000 version: general [root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image ovirt-imageio-proxy-1.4.6-1.el7.noarch ovirt-imageio-common-1.4.6-1.el7.x86_64 ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch I have seen bugs reported to redhat about this but I am running above the affected releases. engine software is 4.2.8.2-1.el7 Any idea what we can tweak to open up this bottleneck?

Yes, I do. Gold crown indeed. It's the "HostedEngine" as seen attached!

Still cannot increase memory for Hosted Engine. From the logs it seams that the engine is trying to hotplug memory to the engine VM which is something it should not happen. The engine should simply update engine VM configuration in the OVF_STORE and require a reboot of the engine VM. Quick question, in the VM panel do you see a gold crown symbol on the Engine VM?
