Controller recomandation - LSI2008/9265
by Leo David 05 Apr '19

05 Apr '19

Hi Everyone, For a hyperconverged setup started with 3 nodes and going up in time up to 12 nodes, I have to choose between LSI2008 ( jbod ) and LSI9265 (raid). Perc h710 ( raid ) might be an option too, but on a different chassis. There will not be many disk installed on each node, so the replication will be replica 3 replicated-distribute volumes across the nodes as: node1/disk1 node2/disk1 node3/disk1 node1/disk2 node2/disk2 node3/disk2 and so on... As i will add nodes to the cluster , I intend expand the volumes using the same rule. What would it be a better way, to used jbod cards ( no cache ) or raid card and create raid0 arrays ( one for each disk ) and therefore have a bit of raid cache ( 512Mb ) ? Is raid caching a benefit to have it underneath ovirt/gluster as long as I go for "Jbod" installation anyway ? Thank you very much ! -- Best regards, Leo David

status of uploaded images complete and not OK
by Gianluca Cecchi 04 Apr '19

04 Apr '19

Hello, I'm using oVirt 4.3.2 and I have an iSCSI based storage domain. I see that if I upload an iso image or a qcow2 file, at the end it remains in "Complete" status and not "OK" See here: https://drive.google.com/file/d/1rTuVB1_MGxudVCx-ok7mE2BirWF0rx7x/view?usp=… I can use them, but it seems a bit strange and in fact I had a problem in putting a host into maintenance due to this. See here: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4UJ75YMYSPW5Q… In fact from db point of view I can see this (for other 2 more uploads done in March as described above), where status remains in phase 9.... engine=# select last_updated, message, bytes_sent, bytes_total,active,phase from image_transfers ; last_updated | message | bytes_sent | bytes_total | active | phase ----------------------------+-----------------------+-------------+-------------+--------+------- 2019-03-14 16:22:11.728+01 | Finalizing success... | 524288000 | 565182464 | t | 9 2019-03-14 16:26:00.03+01 | Finalizing success... | 6585057280 | 6963593216 | t | 9 2019-04-04 17:16:29.889+02 | Finalizing success... | 21478375424 | 21478375424 | f | 9 2019-04-04 19:35:28.688+02 | Finalizing success... | 4542431232 | 4588568576 | t | 9 (4 rows) engine=# Any hint? anyone to verify an upload on block storage on 4.3.2?

Eve-ng KVM acceleration not working in Ovirt
by robertodg＠prismatelecomtesting.com 04 Apr '19

04 Apr '19

Hello everyone! Actually I'm encountering a huge problem that I'll explain in steps, in order to be clear and discursive. First of all, I've deployed eve-ng Community Edition 2.0.3-92 on a KVM with those specs: Server DELL PowerEdge R420 CPU: Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz (24 Core total) RAM: 24GB RAM HDD: 4x 2TB All was working fine, KVM virtualization was working well and i was able to deploy qemu images like PaloAlto (PANOS-8.0.5) with qemu-options accell=kvm without any problem. After an internal company upgrade, i've decided to migrate this tool on Ovirt 4.2, in a node with following specs: SuperMicro Server CPU: Intel (R) Xeon (R) Platinum 8160T @ 2.10GHz (96 Core Total) RAM: 256 GB (16x16) DDR4 2666Mhz Samsung M393A2K40BB2-CTD HDD: x 2 Seagate ST500LM021-1KJ152 SATA 3.0 500GB SSD: x 2 SSD Samsung SSD 850 PRO 1TB NVMe: x 4 KXG50ZNV512G TOSHIBA 512GB (RAID0) Before migration eve-ng had 12 cores, 12 GB RAM and 90 GB HDD. After migration he has now 16 Core, 32GB RAM and RAID0 100GB. On Ovirt Pass-Through Host CPU is activated on VM, CPU nesting is activated too and after new release (2.0.5-95) those are eve-info command logs: eve-ng-info-ovirt: https://paste.fedoraproject.org/paste/Mom-~CXmnlU3cWCUdxPXFg Those are the previous eve-info command logs (on KVM): eve-ng-info-kvm: https://paste.fedoraproject.org/paste/AhqiapiyG5lJcHQBlrbJgw Also, here you can find output of cpuinfo of both node (KVM and Ovirt): cpuinfo-kvm: https://paste.fedoraproject.org/paste/6TQDHxCmiEMosF1qtcdSDQ cpuinfo-ovirt: https://paste.fedoraproject.org/paste/LmieowOvc7WwkEWW9JMduQ On both nodes, output of cat /sys/module/kvm_intel/parameters/nested is Y at least, this is the output of virsh dumpxml of both nodes: eve-ng-ovirt.xml: https://paste.fedoraproject.org/paste/s5SbdWhBHTWJs9O2Be~y8w eve-ng-kvm.xml: https://paste.fedoraproject.org/paste/Yz1E9taAkNT-JyTj8cBR-g However, after migration, i'm not able to deploy qemu images with accell=kvm enabled anymore. With same example PANOS-8.0.5 i'm able to run this qemu image only with this setting removed. Thinking on a migration problem, i've deployed a new eve-ng VM with same specs but problem is still present. Have you any idea on what might be the problem? Thanks for your support.

used network for uploading api
by Nathanaël Blanchet 04 Apr '19

04 Apr '19

Hi all, I noticed a bad transfer when uploading a floating disk through the upload API. I set up two networks, one for management with a dedicated 1Gb link and an other 10Gi for other vlans. It seems that the upload is done by the management network, can anyone confirm it? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Re: [Gluster-users] Gluster 5.5 slower than 3.12.15

Hi i'm unable to start installation of ovirt node because after PXE server booted the installer stuck on an infinite source installation loading (see this: https://scontent-mxp1-1.xx.fbcdn.net/v/t1.0-9/56380126_1095871103950798_594…) My cfg config: default vesamenu.c32 timeout 200 LABEL oVirt43 MENU LABEL oVirt 4.3 KERNEL vmlinuz APPEND initrd=initrd.img inst.stage2=http://192.168.4.200/oVirt430/ Any ideas?

Hi, I have an all in one ovirt 4.2.2 with gluster storage and a couple of windows 2012 VMs. One w2012 is showing actual size 209GiB and Virtual Size 150 GiB on a thin provision disk. The vm shows 30,9 GB of used space. This VM is slower than the others mainly when we reboot the machine it takes around 2 hours. Any idea? Thanks -- Jose Ferradeira http://www.logicworks.pt

Why/how does oVirt fsync over NFS
by Karli Sjöberg 03 Apr '19

03 Apr '19

Hello! This question arose after the (in my opinion) hasty response from a user that thinks oVirt is bad because it cares about the integrity of your data: https://lists.ovirt.org/archives/list/users@ovirt.org/message/QPVXUFW2U3WGJ… Fine, that's their choice. They can have silent data corruption all they want in case of a power failure or something, it's up to them if they think it's worth it. However, I started wondering why oVirt sync's everything over NFS, I know it does because you can in ZFS turn it off by "zfs set sync=disabled <dataset>" and throughput and everything goes through the roof. The right way is of course to add a SLOG or better yet a mirrored pair but just for a quick test or whatever... But their doesn't seem to be any reason why oVirt should do that, that's why I'm asking. Look, this is from the CentOS 'mount' man page: "defaults Use default options: rw, suid, dev, exec, auto, nouser, and async." So therefore 'sync' should be explicitly set on the mount, right? Wrong! # mount | grep -c sync 0 So why then does it sync? The NFS man page says: "The sync mount option The NFS client treats the sync mount option differently than some other file systems (refer to mount(8) for a description of the generic sync and async mount options). If neither sync nor async is specified (or if the async option is specified), the NFS client delays sending application writes to the server until any of these events occur: Memory pressure forces reclamation of system memory resources. An application flushes file data explicitly with sync(2), msync(2), or fsync(3). An application closes a file with close(2). The file is locked/unlocked via fcntl(2)." So which of these things are happening for the Host to send sync calls to the NFS server? Just curious... /K

4.2 / 4.3 : Moving the hosted-engine to another storage
by andreas.elvers+ovirtforum＠solutions.work 03 Apr '19

03 Apr '19

Hi friends of oVirt, Roughly 3 years ago a user asked about the options he had to move the hosted engine to some other storage. The answer by Simone Tiraboschi was that it would largely not be possible, because of references in the database to the node the engine was hosted. This information would prevent a successful move of the engine even with backup/restore. The situation seem to have improved, but I'm not sure. So I ask. We have to move our engine away from our older Cluster with NFS Storage backends (engine, volumes, iso-images). The engine should be restored on our new cluster that has a gluster volume available for the engine. Additionally this 3-node cluster is running Guests from a Cinder/Ceph storage Domain. I want to restore the engine on a different cluster to a different storage domain. Reading the documentation at https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori… I am wondering whether oVirt Nodes (formerly Node-NG) are capable of restoring an engine at all. Do I need EL-based Nodes? We are currently running on oVirt Nodes. - Andreas

HE - engine gluster volume - not mounted
by Leo David 02 Apr '19

02 Apr '19

Hello Everyone, Using 4.3.2 installation, and after running through HyperConverged Setup, at the last stage it fails. It seems that the previously created "engine" volume is not mounted under "/rhev" path, therefore the setup cannot finish the deployment. Any ideea which are the services responsible of mounting the volumes on oVirt Node distribution ? I'm thinking that maybe this particularly one failed to start for some reason... Thank you very much ! -- Best regards, Leo David

trying to use Managed Block Storage in 4.3.2 with Ceph / Authentication Keys
by Matthias Leopold 02 Apr '19

02 Apr '19

Hi, I upgraded my test environment to 4.3.2 and now I'm trying to set up a "Managed Block Storage" domain with our Ceph 12.2 cluster. I think I got all prerequisites, but when saving the configuration for the domain with volume_driver "cinder.volume.drivers.rbd.RBDDriver" (and a couple of other options) I get "VolumeBackendAPIException: Bad or unexpected response from the storage volume backend API: Error connecting to ceph cluster" in engine log (full error below). Unfortunately this is a rather generic error message and I don't really know where to look next. Accessing the rbd pool from the engine host with rbd CLI and the configured "rbd_user" works flawlessly... Although I don't think this is directly connected there is one other question that comes up for me: how are libvirt "Authentication Keys" handled with Ceph "Managed Block Storage" domains? With "standalone Cinder" setups like we are using now you have to configure a "provider" of type "OpenStack Block Storage" where you can configure these keys that are referenced in cinder.conf as "rbd_secret_uuid". How is this supposed to work now? Thanks for any advice, we are using oVirt with Ceph heavily and are very interested in a tight integration of oVirt and Ceph.
