Hi Marko, I guess you can use distributed-replicated volumes and oVirt cluster with host triplets.

Re: Damaged hard disk in volume replica gluster
by Strahil 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.

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..

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.

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 !

ovirt hosted-engine on iSCSI offering one target
by wodel youchi 18 Dec '19

18 Dec '19

Hi, We have an oVirt Platforme using the 4.1 version. when the platforme was installed, it was made of : - Two HP Proliant DL380 G9 as hypervisors - One HP MSA1040 for iSCSI - One Synology for NFS - Two switches, one for network/vm traffic, the second for storage traffic. The problem : the hosted-engine domain was created using iSCSI on the HP MSA. The problem is that this disk array does not give the possibility to create different targets, it presents just one target. At that time we create both the hosted-engine and the first data domain using the same target, and we didn't pay attention to the information saying "i*f you are using iSCSI storage, do not use the same iSCSI target for the shared storage domain and data storage domain*". Question : - what problems can be generated by this (mis-)configuration? - Is this a must to do (correct) configuration. Regards.

hyperconverged single node with SSD cache fails gluster creation
by thomas＠hoberg.net 01 Dec '19

01 Dec '19

I am seeing more success than failures at creating single and triple node hyperconverged setups after some weeks of experimentation so I am branching out to additional features: In this case the ability to use SSDs as cache media for hard disks. I tried first with a single node that combined caching and compression and that fails during the creation of LVMs. I tried again without the VDO compression, but actually the results where identical whilst VDO compression but without the LV cache worked ok. I tried various combinations, using less space etc., but the results are always the same and unfortunately rather cryptic (substituted the physical disk label with {disklabel}): TASK [gluster.infra/roles/backend_setup : Extend volume group] ***************** failed: [{hostname}] (item={u'vgname': u'gluster_vg_{disklabel}p1', u'cachethinpoolname': u'gluster_thinpool_gluster_vg_{disklabel}p1', u'cachelvname': u'cachelv_gluster_thinpool_gluster_vg_{disklabel}p1', u'cachedisk': u'/dev/sda4', u'cachemetalvname': u'cache_gluster_thinpool_gluster_vg_{disklabel}p1', u'cachemode': u'writeback', u'cachemetalvsize': u'70G', u'cachelvsize': u'630G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Physical volume \"/dev/mapper/vdo_{disklabel}p1\" still in use\n", "item": {"cachedisk": "/dev/sda4", "cachelvname": "cachelv_gluster_thinpool_gluster_vg_{disklabel}p1", "cachelvsize": "630G", "cachemetalvname": "cache_gluster_thinpool_gluster_vg_{disklabel}p1", "cachemetalvsize": "70G", "cachemode": "writeback", "cachethinpoolname": "gluster_thinpool_gluster_vg_{disklabel}p1", "vgname": "gluster_vg_{disklabel}p1"}, "msg": "Unable to reduce gluster_vg_{disklabel}p1 by /dev/dm-15.", "rc": 5} somewhere within that I see something that points to a race condition ("still in use"). Unfortunately I have not been able to pinpoint the raw logs which are used at that stage and I wasn't able to obtain more info. At this point quite a bit of storage setup is already done, so rolling back for a clean new attempt, can be a bit complicated, with reboots to reconcile the kernel with data on disk. I don't actually believe it's related to single node and I'd be quite happy to move the creation of the SSD cache to a later stage, but in a VDO setup, this looks slightly complex to someone without intimate knowledge of LVS-with-cache-and-perhaps-thin/VDO/Gluster all thrown into one. Needless the feature set (SSD caching & compressed-dedup) sounds terribly attractive but when things don't just work, it's more terrifying.

Beginning oVirt / Hyperconverged
by email＠christian-reiss.de 25 Nov '19

25 Nov '19

Hey folks! Quick question, really: I have 4 servers of identical hardware. The documentation says "you need 3", not "you need 3 or more"; is it possible to run hyperconverged with 4 servers (in same rack, let's neglect the possibility of 2 failing servers (split brain))? Also: I have a nice seperate server (low power footprint, big on cpu (8) and has 32gb ram)-- would love to use this as engine server only. Can I initiate a hyperconverged system with 4 working host starting from a stand-alone engine? Or does "hyperconverged" a must for HA engine on the cluster? One last one: Installing ovirt nodes, obviously. This will by default create a lvm across the entire RAID volume; can I simply create folders (with correct permissions) and use those as gluster bricks? Or do I need to partition the RAID in a special way? Thanks for your pointers, Chris.

Good Day I have to change the IP addresses of the oVirt Engine, hosts and storage to a new IP range. Please, can you advise the best way to do this and if there is anything I would need to change in the database? I have also run into an issue where someone has removed the ISO share/data on the storage, so I am unable to remove, activate, detach or even add a new ISO share.

DHCP Client in Guest VM does not work on ovirtmgmt
by ccesario＠blueit.com.br 13 Nov '19

13 Nov '19

Hello, Is there any special config to usage dhcp client on Guest VM using ovirtmgmt/ovirtmgmt vnic profile ? Currently I have a VM using the ovirtmgmt/ovirtmgmt NIC profile and this interface is configured as DHCP client, and this does not work when using ovirtmgmt/ovirtmgmt as NIC profile. But if I assign manual IP address from the same range of DHCP server the comunication it works. And If usage other NIC profile in other VLAN with other DHCP server it works. It seems ovirtmgmt/ovirtmgmt profile filter the DHCP protocol. Could someone has idea to allow DHCP protocol works on ovirtmgmt/ovirtmgmt NIC profile? Best regards Carlos

External networks issue after upgrading to 4.3.6
by ada per 13 Nov '19

13 Nov '19

After upgrading to the latest stable version the external networks lost all functionality. Under providers-->ovn-network-provider the test runs successfully. But when im creating an external provider network, attaching it to a router as a LAN setting up dhcp lease it is not reachable from other VMs in the same network. Hosts and hosted engine can't seem to ping it either. I tried disabling firewalls on both hosted engines, VMs and host and still nothing. When configuring Logical networks or VLANs they work perfectly tje one problem is the external networks. I have another environment running on a previous version of ovirt and it works perfectly there. I think its a bug. Thanks for your help

After importing the ovirt-engine 4.3.5 backup file into ovirt-engine 4.3.6, will the information of the ovirt-engine 4.3.6 management interface be the same as ovirt-engine 4.3.5?
by wangyu13476969128＠126.com 11 Nov '19

11 Nov '19

The current version of ovirt-engine in production environment is 4.3.5.5. In order to prevent the ovirt-engine machine from being down, the management interface cannot be used, according to the relevant link: https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html I backed it up using the command: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name I have prepared another machine as a spare machine. Once the ovirt-engine is down in the production environment, the standby machine can be UP and the standby machine can manage the ovirt-nodes. According to the relevant links: https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html The ovirt-engine is installed on the standby machine. After I have executed these three commands: 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine I found that the ovirt-engine version of the standby machine is 4.3.6 So my question is: 1. The ovirt-engine version of the standby machine is 4.3.6, and the production environment ovirt-engine version is 4.3.5.5, which command is used on the production environment ovirt-engine machine: engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name Files obtained after using the backup command on the ovirt-engine in the production environment are restored using these two files under the standby computer. Will the information on the ovirt-engine management interface of the standby computer be consistent with the ovirt-engine of the production environment (eg data center, host, virtual machine, etc.)? 2. Can the ovirt-engine of the standby machine be installed with version 4.3.5.5? How do I need to modify the following three commands to get the backup machine to install the version 4.3.5.5? 1. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. yum update 3. yum install ovirt-engine

Can ovirt-node support multiple network cards ？
by wangyu13476969128＠126.com 07 Nov '19

07 Nov '19

Can ovirt-node support multiple network cards ？ I download ovirt-node-ng-installer-4.3.5-2019073010.el7.iso from ovirt site. And install on a Dell R730 Server. The version of ovirt-engine is 4.3.5.5. I found that the logic network ovirtmgmt can only point to one network card interface. Can ovirt-node support multiple network cards ？ If yes , please tell me the method.

How to pass parameters between VDSM Hooks domxml in single run
by Vrgotic, Marko 06 Nov '19

06 Nov '19

Dear oVIrt, A while ago we discussed on ways to change/update content of parameters of domxml in certain action. As I mentioned before, we have added the VDSMHook 60_nsupdate which removes the DNS record entries when a VM is destroyed: … domxml = hooking.read_domxml() name = domxml.getElementsByTagName('name')[0] name = " ".join(name.nodeValue for name in name.childNodes if name.nodeType == name.TEXT_NODE) nsupdate_commands = """server {server_ip} update delete {vm_name}.example.com a update delete {vm_name}. example.com aaaa update delete {vm_name}. example.com txt send """.format(server_ip="172.16.1.10", vm_name=name) … The goal: However, we did not want to execute remove dns records when VM is only migrated. Since its considered a “destroy” action we took following approach. * In state “before_vm_migrate_source add hook which will write flag “is_migration” to domxml * Once VM is scheduled for migration, this hook should add the flag “is_migration” to domxml * Once 60_nsupdate is triggered, it will check for the flag and if there, skip executing dns record action, but only remove the flag “is_migration” from domxml of the VM … domxml = hooking.read_domxml() migration = domxml.createElement("is_migration") domxml.getElementsByTagName("domain")[0].appendChild(migration) logging.info("domxml_updated {}".format(domxml.toprettyxml())) hooking.write_domxml(domxml) … When executing first time, we observed that flag “ <name>hookiesvm</name> <uuid>fcfa66cb-b251-43a3-8e2b-f33b3024a749</uuid> <metadata xmlns:ns0="http://ovirt.org/vm/tune/1.0" xmlns:ns1="http://ovirt.org/vm/1.0"> <ns0:qos/> <ovirt-vm:vm xmlns:ovirt-vm="http://ovirt.org/vm/1.0"> <ovirt-vm:clusterVersion>4.3</ovirt-vm:clusterVersion> <ovirt-vm:destroy_on_reboot type="bool">False</ovirt-vm:destroy_on_reboot> <ovirt-vm:launchPaused>false</ovirt-vm:launchPaused> <ovirt-vm:memGuaranteedSize type="int">1024</ovirt-vm:memGuaranteedSize> <ovirt-vm:minGuaranteedMemoryMb type="int">1024</ovirt-vm:minGuaranteedMemoryMb> ...skipping... <address bus="0x00" domain="0x0000" function="0x0" slot="0x09" type="pci"/> </rng> </devices> <seclabel model="selinux" relabel="yes" type="dynamic"> <label>system_u:system_r:svirt_t:s0:c169,c575</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c169,c575</imagelabel> </seclabel> <seclabel model="dac" relabel="yes" type="dynamic"> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> <is_migration/> </domain> is added to domxml, but was present once 60_nsupdate hook was executed. The question: How do we make sure that, when domxml is updated, that the update is visible/usable by following hook, in single run? How to pass these changes between hooks? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Re: oVirt/RHV 4.3.6: How to boot a Q35/UEFI VM from CD?

I have successfully managed to boot and install RHEL & openSUSE with Secureboot, but UEFI variables are not saved and requires some workarounds (there is a bug opened for that) to work.

I'm not sure, but you can try with replica 1 gluster volume. Later that gluster volume can be changed to replica 2 arbiter 1 or even better replica 3 volume.
