Storage Domain already attached to a Data Center
by Anton Louw 17 Mar '20

17 Mar '20

Hi All, I created a little test environment for myself, just to test a few things. The initial test I wanted to do was to see if I can create a new HE, add it to a different Storage Domain, and then import my existing Storage Domains. Everything went through 100%, except for the little option I forgot to select, and that is to put the original Data Center in maintenance. Now, when I want to import my storage domains, it tells me that the storage domain is already attached to a data center. Is there any way that I can remove this storage domain from my original data center through one of my nodes? I would power up the old HE, but I have powered it off just before deploying a new HE. I am having the same issue with a node as well, so if there is a way to remove the node from the Data Center as well, that would be awesome.

I configured my DWH scale with scales that I would like to report on. I checked this morning, and the last row in my PostgreSQL DB is from the 9th. I checked the logs, and I see that it is referring to an “ETL Service” which I am not familiar with. I have attached the lines in the text document. Where is this from? If from the engine db, please check also: /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log Then try to (re)start it with: systemctl restart ovirt-engine-dwhd.service ETL is a common name in the industry for what dwhd does: Extract, Transform, Load. > > > > If anybody could point me in the right direction, it would be greatly appreciated. > > > > Thank you > > > Anton Louw > Cloud Engineer: Storage and Virtualization at Vox > ________________________________ > T: 087 805 0000 | D: 087 805 1572 > M: N/A > E: anton.louw(a)voxtelecom.co.za > A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg > www.vox.co.za > > > > > > > > > Disclaimer > > The contents of this email are confidential to the sender and the intended recipient.

Migrate engine from one storage domain to another

Hi All, What would be the easiest way to migrate my hosted engine disk from one storage domain, to another? I see that I can click on the disk, and select move, but for some reason I feel nervous about it :) Thanks

Client separation on bridge level
by Hendrik Peyerl 16 Mar '20

16 Mar '20

Hello everyone, is there a way to seperate the traffic between VMs on the same bridge on one oVirt-node with built-in tools from ovirt? We have VMs using the same bridge which should never be able to talk to each other. We are currently using ebtables for that, but its not working very good anymore now that we upgraded to 4.3 with firewalld. Any suggestions would be greatly appreciated. Best regards, Hendrik

Ansible playbook timeout
by Barrett Richardson 15 Mar '20

15 Mar '20

Version 4.2.8.2-1.0.9.el7 Per the info near the bottom of /usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.conf I should be able to create this file, /etc/ovirt-engine/engine.conf.d/99-ansible-playbook-timeout.conf and place in the file these contents, ANSIBLE_PLAYBOOK_EXEC_DEFAULT_TIMEOUT=150 and extend the playbook timeout. It doesn't work, still times out after 30 minutes. Any suggested workarounds?

strange error when editing multiple disks
by Gianluca Cecchi 15 Mar '20

15 Mar '20

I'm noticing this on 4.3.8 and I don't have understood exactly the raising condition, if UI based or what At first I thought it was the bootable flag, but it is not, apparently vm1 powered on with two disks I select the VM then Disks subtab select line of second disk --> edit --> OK All goes well Then, remaining in the same Disks subtab window I select the line of the first disk --> Edit --> OK And now I get the error window: " Error while executing action: vm1: - Cannot edit Virtual Disk. At least one of the VMs is not down. " ? Then I go and select another powered on VM, vm2, with only one disk, the one with bootable flag, and I'm able to edit it successfully. Then I come back and select vm1 and Disks subtab, select again the first line of the boot disk --> Edit --> OK and I'm able to edit with success..... but eg if I want to modify both alias and description fields I have to do one at a time, otherwise if in the same window I try to modify both and then press OK I still get the error message above. Can anyone verify/test? I was able to reproduce on bot oVirt 4.3.8 and RHV 4.3.8 Gianluca

Re: upgrade from 4.38 to 4.39
by eevans＠digitaldatatechs.com 14 Mar '20

Since the upgrade, for some reason I get this message when checking for upgrade on one host: Failed to check for available updates on host kvm01 with message 'Failed to run check-update of host 'kvm01.digitaldatatechs.com'. Error: fatal: [kvm01.digitaldatatechs.com] FAILED! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).", "unreachable": true} I can ssh into the server from the ovirt server and re-copied the ssh keys and authorized keys but the problem persists. I am still unable to manually migrate but auto load balance seems to be working again. I am attaching the engine log for your review. Thank you so much for your help.
