Hi All, I noticed that Red Hat Gluster Storage Console is based on oVirt's web interface. Does anyone know how to deploy it on CentOS 8 for managing Gluster v8.X ? Best Regards, Strahil Nikolov

upload_disk.py - CLI Upload Disk
by Jorge Visentini 03 Jan '21

03 Jan '21

Hi All. I'm using version 4.4.4 (latest stable version - ovirt-node-ng-installer-4.4.4-2020122111.el8.iso) I tried using the upload_disk.py script, but I don't think I knew how to use it. When I try to use it, these errors occur: *python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py disk01-SO.qcow2 --disk-format qcow2 --sd-name ISOsusage: upload_disk.py [-h] -c CONFIG [--debug] [--logfile LOGFILE] [--disk-format {raw,qcow2}] [--disk-sparse] [--enable-backup] --sd-name SD_NAME [--use-proxy] [--max-workers MAX_WORKERS] [--buffer-size BUFFER_SIZE] filenameupload_disk.py: error: the following arguments are required: -c/--config* Using the upload_disk.py help: *python3 upload_disk.py --help-c CONFIG, --config CONFIG Use engine connection details from [CONFIG] section in ~/.config/ovirt.conf.* This CONFIG, is the API access configuration for authentication? Because analyzing the script I did not find this information. Does this new version work differently or am I doing something wrong? In the sdk_4.3 version of upload_disk.py I had to change the script to add the access information, but it worked. *[root@engineteste01 ~]# python3 upload_disk.py disk01-SO.qcow2Checking image...Disk format: qcow2Disk content type: dataConnecting...Creating disk...Creating transfer session...Uploading image...Uploaded 20.42%Uploaded 45.07%Uploaded 68.89%Uploaded 94.45%Uploaded 2.99g in 42.17 seconds (72.61m/s)Finalizing transfer session...Upload completed successfully[root@engineteste01 ~]#* Thank you all!! -- Att, Jorge Visentini +55 55 98432-9868

Windows 7 vm lost network connection under heavy network load
by Joey Ma 03 Jan '21

03 Jan '21

Hi folks, Happy holidays. I'm having an urgent problem :smile: . I've installed oVirt 4.4.2 on CentOS 8.2 and then created several Windows 7 vms for stress testing. I found that the heavy network load would lead to the e1000 net card NOT able to receive packets, it seemed totally blocked. In the meantime, packet sending was fine. Only re-enabling the net card can restore the network. Has anyone also had this problem? Looking forward to your insights. Much appreciated. Best regards, Joey

Cannot upgrade cluster to v4.5 (All hosts are CentOS 8.3.2011)
by Gilboa Davara 31 Dec '20

31 Dec '20

Hello all, I'm more-or-less finished building a new ovirt over glusterfs cluster with 3 fairly beefy servers. Nodes were fully upgraded to CentOS Linux release 8.3.2011 before they joined the cluster. Looking at the cluster view in the WebUI, I get an exclamation mark with the following message: "Upgrade cluster compatibility level". When I try to upgrade the cluster, 2 of the 3 hosts go into maintenance and reboot, but once the procedure is complete, the cluster version remains the same. Looking at the host vdsm logs, I see that once the engine refreshes their capabilities, all hosts return 4.2-4.4 and not 4.5. E.g. 'supportedENGINEs': ['4.2', '4.3', '4.4'], 'clusterLevels': ['4.2', '4.3', '4.4'] I assume I should be seeing 4.5 after the upgrade, no? AmI missing something? Thanks, - Gilboa

Best Practice? Affinity Rules Enforcement Manager or High Availability?
by souvaliotimaria＠mail.com 31 Dec '20

31 Dec '20

Hello everyone, Not sure if I should ask this here as it seems to be a pretty obvious question but here it is. What is the best solution for making your VMs able to automatically boot up on another working host when something goes wrong (gluster problem, non responsive host etc)? Would you enable the Affinity Manager and enforce some policies or would you set the VMs you want as Highly Available? Thank you very much for your time! Best regards, Maria Souvalioti

Re: Breaking up a oVirt cluster on storage domain boundary.

> Can I migrate storage domains, and thus all the VMs within that > storage domain? > > > > Or will I need to build new cluster, with new storage domains, and > migrate the VMs? > > Actually you can create a new cluster and ensure that the Storage domains are accessible by that new cluster. Then to migrate, you just need to power off the VM, Edit -> change cluster, network, etc and power it up. It will start on the hosts in the new cluster and then you just need to verify that the application is working properly. Best Regards, Strahil Nikolov
