I've added a new user using the CLI ovirt-aaa-jdbc-tool. I've also been able to modify the attributes of the new user and list all the modifications. However the new user does ot show up in the web GUI, a password has been assigned and the user is assigned to the '*' Name Space. What must be done to have the user show up in the web gui? Thanks

What is the easiest way to clone a template using rest api. I know I can create a VM from a template then make a new template from this new VM but I would like to just clone a template directly so I can maintain different branches TIA

Password at install for admin@internal not working
by louisb＠ameritech.net 29 Jul '21

29 Jul '21

I've installed ovirt several times on a fresh machine from scratch. I've had no problems with the install however I'm unable to login via the web console using the assigned password entered at the time of the install. On the last 3 tries I've kept the password simple to insure that I was not entering the assigned password incorrectly. I continued tp get with each install the message: Unable to log in. Verify your login information or contact the system administrator. I've checked the install log for errors and not found any. While trying to keep the password simple I was warned about the simplicity password but decided to continue because of previous attempts were not successful. are there any addtitional log that I can view to help with this issue? Is there possibly a bug in the install process that has a work around? Thanks

This repros for me on a clean install on top of RHEL 8.4. logs show a failed attempt to run sudo around the same time (which fails because password is required & there's no way to provide it).

by Chris Adams 27 Jul '21

27 Jul '21

I was looking at using direct Linux kernel/initrd booting for a particular automation project, but I'm not sure how to use it. The docs talk about referencing files from an ISO domain, but those are deprecated (and I don't have one). Can the files be in a regular data domain? How would I specify which domain to look in? The docs also say the alternative is to specify a path "on the host", but I guess that requires the files to be copied to the same path on every host that could boot the VM? I guess I can instead make a one-off ISO and upload it to a data domain; it just would be easier to use direct boot. -- Chris Adams <cma(a)cmadams.net>

Requirements to put to cluster version 4.6
by Gianluca Cecchi 27 Jul '21

27 Jul '21

Hello, I updated all my 3 CentOS 4.4.5 hosts to 4.4.6. Or at least upgrading them from the GUI I see now they are on CentOS 8.4 and: [root@ov200 ~]# rpm -qa| grep 4.4.6 ovirt-release44-4.4.6.3-1.el8.noarch ovirt-host-4.4.6-1.el8.x86_64 ovirt-host-dependencies-4.4.6-1.el8.x86_64 [root@ov200 ~]# How to see from the webadmin GUI or from the Host Console that they are indeed 4.4.6? If I try to set cluster compatibility version to 4.6 I get: Error while executing action: Cannot change Cluster Compatibility Version to higher version when there are active Hosts with lower version. -Please move Host ov300, ov301, ov200 with lower version to maintenance first. I don't remember the need of giving downtime to get new cluster version... Or what are further requirements (and benefits....) to upgrade to 4.6? Thanks, Gianluca

ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(score) Penalizing score by 1600 due to network status
by Christoph Timm 26 Jul '21

26 Jul '21

Hi List, I'm trying to understand why my hosted engine is moved from one node to another from time to time. It is happening sometime multiple times a day. But there are also days without it. I can see the following in the ovirt-hosted-engine-ha/agent.log: ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(score) Penalizing score by 1600 due to network status After that the engine will be shutdown and started on another host. The oVirt Admin portal is showing the following around the same time: Invalid status on Data Center Default. Setting status to Non Responsive. But the whole cluster is working normally during that time. I believe that I have somehow a network issue on my side but I have no clue what kind of check is causing the network status to penalized. Does anyone have an idea how to investigate this further? Best regards Christoph

Gluster bricks error
by Patrick Lomakin 24 Jul '21

24 Jul '21

For a long time I have been seeing the same error, which cannot be corrected.After restarting the host which has a Volume of one or more Bricks, the Volume starts with the status "Online", but the Bricks remain "Offline". This leads to having to manually restart Volume, the ovirt-ha and ovirt-broker services, and run the hosted-engine --connect-storage command. And only after that I can start the hosted engine back to normal. I tried this on different server hardware and different operating systems for the host, but the result is the same. This is a very serious flaw that nullifies the high availability in HCI using GlusterFS.Regards!

Create gluster brick in oVirt engine, RAID-parameters
by Dominique D 23 Jul '21

23 Jul '21

Hi, When creating a gluster brick in oVirt (host->Storage Devices->Create Brick), I have to fill in the parameters of the RAID volume the brick : RAID-type, number of disks and stripe size. My setup is DELL RAID Controler PERC H710 4 SSD disks raid5 Default stripe for Dell RAID-controller defaults is 64KB. I have no choice of a Raid 5 and if I choose Raid6, 4 or 3 disk, 64KB or 128KB Stripe. It does not work, (Failed to create brick data_ssd on host xxx of cluster Default). The only option that works is RAID type = None tried to find information about this, but no luck yet.. I tried ovirt engine 4.4.1.10 and lastest 4.4.7.6 Can I leave this to None ? Performance ? Thank you

4.4.7 gluster quorum problem
by radchenko.anatoliy＠gmail.com 22 Jul '21

22 Jul '21

Hi guys, one strange thing happens, cannot understand it. Today i installed last version 4.4.7 on centos stream, replica 3, via cockpit, internal lan for sync. Seems all ok, if reboot 3 nodes together aslo ok. But if i reboot 1 node ( and declare node rebooted through web ui) the bricks (engine and data) remain down on that node. All is clear on logs without explicit indication of the situation except "Server quorum regained for volume data. Starting local bricks" on glusterd.log. After "systemctl restart glusterd" bricks gone down on another node. After "systemctl restart glusterd" on that node all is ok. Where should i look? some errors of log that i found: --------------------------------------------- bdocker.log: statusStorageThread::ERROR::2021-07-12 22:17:02,899::storage_broker::223::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(put_stats) Failed to write metadata for ho$ Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/ovirt_hosted_engine_ha/broker/storage_broker.py", line 215, in put_stats f = os.open(path, direct_flag | os.O_WRONLY | os.O_SYNC) FileNotFoundError: [Errno 2] No such file or directory: '/run/vdsm/storage/53b068c1-beb8-4048-a766-3a4e71ded624/d3df7eb6-d453-439a-8436-d3694d4b5179/de18b2cc-a4e1-4afc-9b5a-6063$ StatusStorageThread::ERROR::2021-07-12 22:17:02,899::status_broker::90::ovirt_hosted_engine_ha.broker.status_broker.StatusBroker.Update::(run) Failed to update state.

Cannot start hosted-engine
by Valerio Luccio 21 Jul '21

21 Jul '21

Hi list, I have a hosted engine running on a CentOS 8. The engine and all the VM's are stored on a 4-node gluster. I had some issues with the gluster and then the hosted-engine stopped working (even though the virtualization dashboard showed 4 virtual machines running). I tried to "systemctl restart" the hosted-engine, but it failed. I try to reboot the server and the hosted-engine still will not come up.

The fqdn of the hosted engine resolves fine on the server, so does the fqdn of the server itself. The ip address it seems to try to use for the network is that of one of the university's gateways. Any ideas ? Any way to debug this further ?

Reconfigure Gluster from Replica 3 to Arbiter 1/Replica 2
by David White 21 Jul '21

21 Jul '21

My current hyperconverged environment is replicating data across all 3 servers. I'm running critically low on disk space, and need to add space. To that end, I've ordered 8x 800GB ssd drives, and plan to put 4 drives in 1 server, and 4 drives in the other. What's my best option for reconfiguring the hyperconverged cluster, to change gluster storage away from Replica 3 to a Replica 2 / Arbiter model? I'd really prefer not to have to reinstall things from scratch, but I'll do that if I have to. My most important requirement is that I cannot have any downtime for my VMs (so I can only reconfigure 1 host at a time). Sent with ProtonMail Secure Email.

Automatic Shutdown / Startup for Hosted-Engine
by Eugène Ngontang 18 Jul '21

18 Jul '21

Hi, I understood we have to put hosted-engine into maintenance mode and shutdown the VMs if we want to power off the host (otherwise it will reboot). I'm setting up a process to - put the HestedEngine in global maintenance mode (*hosted-engine --set-maintenance --mode=global*) - shutdown the HostedEngine (*hosted-engine --vm-shutdown*) - PowerOff the HostedEngine (*hosted-engine --vm-poweroff*) - Power off the server (*shutdown -P*) Everything works fine and I can start the server back up, remove the HostedEngine from maintenance mode, and it will start automatically running. The issue is when bringing up hosted-engine: all VMs come up but one (*BigIP*) and I am trying to see if there is way to bring it up without having to store the engine password (using the *ovirt_vm* API). At the moment, I am having to look for the BigIP VM and then use credentials to bring it up: it will not come up with 'hosted-engine --vm-start' Is there to make this specific VM start the same time as the others VM automatically when HostedEngine starts? Thanks for your help.

Removing Direct Mapped LUNs
by Ryan Chewning 16 Jul '21

16 Jul '21

Hi List, We need to add and remove directly mapped LUNs to multiple VMs in our Non-Production environment. The environment is backed by an iSCSI SAN. In testing when removing a directly mapped LUN it doesn't remove the underlying multipath and devices. Several questions. 1) Is this the expected behavior? 2) Are we supposed to go to each KVM host and manually remove the underlying multipath devices? 3) Is there a technical reason that oVirt doesn't do this as part of the steps to removing the storage? This is something that was handled by the manager in the previous virtualization that we used, Oracle's Xen based Oracle VM. Thanks! Ryan

ovirt (two nodes & iscsi san)
by edp＠maddalena.it 16 Jul '21

16 Jul '21

Hi. i am trying to set up an environment with two ovirt nodes connected to a san in iscsi. every node has a direct connection to the san (with a point-to-point connection). so every node talks with the san on a different iscsi channel with a different ip. in this case (i have just tried) when I shut down ovirt-node1 the ovirt-engine cannot restart automatically on ovirt-node2. maybe this because when I have configured hosted engine I have moved the engine storage to the iscsi lun that only the node1 can see (the ovirt-engine-setup asks for the iscsi ip address). In this case how can I resovle my problem? other than moving the ovirt-engine from one node to the other I have also to publish other luns to both ovirt nodes. but if every node talks only with one channel of the iscsi san I think that this won't working. If i put a 10 gb switch between ovirt-nodes and san channels can working? what I would like to do is connect the two ovirt nodes to the switch and also the two iscsi channels of the san to the switch. in this way each node should be able to talk to the san on both ip (iscsi channels) thank you
