Reimport disks
by Christian Reiss 13 Feb '20

13 Feb '20

Hey folks, I created a new cluster with a new engine, everything is green and running again (3 HCI, Gluster, this time Gluster 7.0 and CentOS7 hosts). I do have a backup of the /images/ directory from the old installation. I tried copying (and preserving user/ permissions) into the new images gluster dir and trying a domain -> scan to no avail. What is the correct way to introduce oVirt to "new" (or unknown) images? -Chris. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

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.

Hello, I am a student and as a school project i have to make virtual environment using oVirt.I am still confused how exactly oVirt is working i just installed its engine with the default settings that are recomended in the guide and i am trying ot make a new host with the default data center and cluster. The host is created but it is staying in installFailed mode. http://prntscr.com/r0u2eo I am using the ip address of the device (It is headless server) that has the oVirt-engine. I already checked if the virtualization is enabled in the bios because i thought it might be the problem. When i checked the engine.log file for test1(it is the name of the host i am trying to make) i got this: 2020-02-11 11:21:29,582-05 ERROR [org.ovirt.engine.core.bll.hostdeploy.AddVdsCommand] (default task-5) [602685d9-6eb3-415f-b705-f94a76b1f77a] Failed to authenticate session with host 'test1': SSH authentication to 'root(a)192.168.66.1' failed.

DataAccessResourceFailureException from one to to the next
by gregor 12 Feb '20

12 Feb '20

After one day I'm not able to login to the ovirt-engine webinterface with the following error message: "org.springframework.dao.DataAccessResourceFailureException: Error retrieving database metadata; nested exception is org.springframework.jdbc.support.MetaDataAccessException: Error while extracting DatabaseMetaData; nested exception is org.postgresql.util.PSQLException: This connection has been closed." Things I tried which didn't help: - engine: check if the database is up - eninge: reboot - hosts: reboot - engine: xfs_repair Any ideas? regards gregor

Ovirt with Ceph
by systems＠oisystems.co.uk 11 Feb '20

11 Feb '20

is it possible to crate a storage pool on the same Centos hosts as the Gluster Storage ? if we use Gluster for the Hosted engine and use Ceph for VM's ? it seems Ceph is much more stable than Gluster and I like the way storage is more transparent in Ceph

Compatibility version for VmPools
by nicolas＠devels.es 11 Feb '20

11 Feb '20

Hi, We recently upgraded to 4.3.8 from 4.1.9. In the update process we set Cluster and DataCenter compatibility versions to 4.3, but now we're facing a problem with VmPools. They cannot be edited and 4.1 as compatibility level is still forcibly set. That means that when new machines are added to the pool, compatibility version 4.1 is set on them and they cannot be started as a message stating the following pops up: Failed to run VM XXX-34 due to a failed validation: [Cannot run VM. The Custom Compatibility Version of VM XXX-34 (4.1) is not supported in Data Center compatibility version 4.3.] (User: admin@internal). Is there a workaround to start those machines, or a way to fix the problem? Thanks.

Update hosted engine to 4.3.8 from 4.3.7 questions
by d03＠bornfree.org 10 Feb '20

10 Feb '20

I'd like to update my hosted engine to version 4.3.8 from 4.3.7, but have concerns. First, on the hosted engine, yum reports that several packages are version locked. Specifically: 0:ovirt-engine-webadmin-portal-4.3.8.2-1.el7.* 0:ovirt-engine-dwh-4.3.8-1.el7.* 0:ovirt-engine-tools-backup-4.3.8.2-1.el7.* 0:ovirt-engine-restapi-4.3.8.2-1.el7.* 0:ovirt-engine-dbscripts-4.3.8.2-1.el7.* 0:ovirt-engine-4.3.8.2-1.el7.* 0:ovirt-engine-backend-4.3.8.2-1.el7.* 0:ovirt-engine-tools-4.3.8.2-1.el7.* Is this normal and is it okay to proceed with the update? If it is not normal, what can I do to correct the problem? Also, what is the correct procedure to update the engine? Although I tried to read the documentation, I have encountered conflicting documents so I must ask. Sorry. This is how I understand it, but am not confident that it is correct: 1. Enable Global HA Maintenance mode. 2. On the engine, run # yum update ovirt* 3. On the engine, run # engine-setup 4. On the engine, run # yum update 4. Reboot the hosted engine. Is "systemctl reboot" acceptable or do I have to do a "hosted-engine --vm-restart" from a host? 5. Disable Global HA Maintenance mode. Your expert guidance is much appreciated.

issue connecting 4.3.8 node to nfs domain

10 Feb '20

Hi, Something weird is going on with our ovirt node 4.3.8 install mounting a nfs share. We have a NFS domain for a couple of backup disks and we have a couple of 4.2 nodes connected to it. Now I'm adding a fresh cluster of 4.3.8 nodes and the backupnfs mount doesn't work. (annoying you cannot copy the text from the events view) The domain is up and working ID:f5d2f7c6-093f-46d6-a844-224d92db5ef9 Size:10238 GiB Available:2491 GiB Used:7747 GiB Allocated:3302 GiB Over Allocation Ratio:37% Images:7 Path:*.*.*.*:/data/ovirt NFS Version:AUTO Warning Low Space Indicator:10% (1023 GiB) Critical Space Action Blocker:5 GiB But somehow the node appears to thin thinks it's an LVM volume?

Error while making hosts
by krisibo01＠gmail.com 09 Feb '20

09 Feb '20

Hello, I am a student and as a school project i have to make virtual environment using oVirt. I just installed the oVirt-engine with the recomended configuration in the documentation and when i try to make a new host i got this error: Error while executing action: Cannot add Host. Connecting to host via SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details. When i checked the log file the only thing that was there is that there is: 2020-02-06 03:59:24,594-05 ERROR [org.ovirt.engine.core.bll.hostdeploy.AddVdsCommand] (default task-30) [d54ee4df-32c8-474c-b315-51ad1131091a] Failed to establish session with host 'test': SSH connection timed out connecting to 'root(a)10.10.0.20' I was trying to make the host following this steps: Adding a Host to the oVirt Engine 1.Click Compute → Hosts. 2.Click New. 3.Use the drop-down list to select the Data Center and Host Cluster for the new host. 4.Enter the Name and the Hostname of the new host. The standard SSH port, port 22, is auto-filled in the SSH Port field. 5.Select an authentication method to use for the Engine to access the host. Enter the root user’s password to use password authentication. Alternatively, copy the key displayed in the SSH PublicKey field to /root/.ssh/authorized_keys on the host to use public key authentication. 6.Click the Advanced Parameters button to expand the advanced host settings. i. Optionally disable automatic firewall configuration. ii. Optionally add a host SSH fingerprint to increase security. You can add it manually, or fetch it automatically. 7.Optionally configure Power Management, SPM, Console, Network Provider, and Kernel. See Explanation of Settings and Controls in the New Host and Edit Host Windows for more information. Hosted Engine is used when deploying or undeploying a host for a self-hosted engine deployment. 8.Click OK. The new host displays in the list of hosts with a status of Installing, and you can view the progress of the installation in the details pane. After a brief delay the host status changes to Up.
