Re: Damaged hard disk in volume replica gluster
by Strahil 25 Feb '20

25 Feb '20

As you are replacing an old brick, you have to recreate the old LV and mount it on the same location. Then you can use the gluster's "reset-brick" (i thing ovirt UI has that option too) and all data will be replicated there. You got also the "replace-brick" option if you decided to change the mount location. P.S.: with replica volumes your volume should be still working, in case it has stopped - you have to investigate before proceeding.

Hello, I'm interested by installing okd on ovirt with the official openshift installer (https://github.com/openshift/installer) but ovirt is not yet supported. Regarding https://bugzilla.redhat.com/show_bug.cgi?id=1578255 and https://lists.ovirt.org/archives/list/users@ovirt.org/thread/EF7OQUVTY53GV3… , how ovirt 4.3.7 should integrate openshift installer integration with terraform? -- 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

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.

Re: Cannot Increase Hosted Engine VM Memory
by Serhiy Morhun 13 Feb '20

13 Feb '20

Hello, did anyone find a resolution for this issue? I'm having exactly the same problem: Hosted Engine VM is running with 5344MB of RAM, when trying to increase to 8192 it would not accept the change because the difference is not divisible by 256. When trying to increase to 8160 the change is accepted but log shows "Hotset memory: changed the amount of memory on VM HostedEngine from 5344 to 5344" at the same time amount of guaranteed memory does increase to 8160 which, in turn, starts generating error messages that VM does not have all the guaranteed RAM.

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.

Also here one interesting point, after installing just "yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm" on this node i try to install this node from engine web interface with "Deploy" action. 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.

Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing

I got upgraded to RC3 and now cannot power any VM . Constantly getting I/O error, but checking at gluster level - I can dd from each disk or even create a new one. Removing the HighAvailability doesn't help. I guess I should restore the engine from the gluster snapshot and rollback via 'yum history undo last'. Does anyone else have my issues ?

Hi, I'm running ovirt Version:4.3.4.3-1.el7 My filesystem disk has 30 GB free space. Cannot start a VM due to an I/O error storage. When tryng to move the disk to another storage domain get this error: Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain DATA4. The sum of pre-allocated disk is the total of the storage domain disk. Any idea what can I do to move a disk to other storage domain? Many thanks -- Jose Ferradeira http://www.logicworks.pt

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 !
