oVirt Node 4.1.1 Hosted Engine Deployment Fibre Channel No LUNS found
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

I've an external RAID subsystem connect to the host by SAS cable (SFF-8644). I follow the instructions of the RAID card manufacture. Include the driver during host installation. And I can see the created RAID volumes (LUNs) available in "Installation Destination". Although I choose to install the engine in host local disk. The installation success and I proceed to hosted engine deployment by Cockpit. And now I stuck at part 4 Storage. I believe "Storage Type" select "Fibre Channel" is correct even I'm not using fibre cable. As NFS and iSCSI are utilize network. I confirm there are 2 RAID volume (LUN0 & LUN1) created in the external RAID subsystem. Why oVirt cannot discover them. What could be wrong :(

Hosted Engine Deployment stuck at 3. Prepare VM
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

oVirt Node version is 4.4.1. This version can successful deploy before. But after I compile the RAID driver. It now stuck at Prepare VM. The last message is "[ INFO ] TASK [ovirt.hosted_engine_setup : Install ovirt-engine-appliance rpm]" According to the instructions from RAID controller manufacture. I'd install the "kernel-headers-xxx.rpm" and "kernel-devel-xxx.rpm" which extracted from official CentOS 8.2.2004 ISO. Also include a bunch of packages for compile driver (e.g. gcc, make, zlib-devel, etc.) I think those packages ruined the deployment. But I still want to know it actually stuck at which part and the reason. Is there any way to check the deployment log?

ovirt4.4 and ldap auth with starttls
by Jiří Sléžka 11 Aug '20

11 Aug '20

Hello, better start new thread... it looks like tls1.0 is not supported anymore in ovirt-engine-extension-aaa-ldap I just migrated engine from 4.3 to 4.4 and cannot use my ldap profile because server_error: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(The server selected protocol version TLS10 is not accepted by client preferences [TLS12]), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb but when I try to force tls 1.0 by setting ... pool.default.ssl.startTLS = true pool.default.ssl.startTLSProtocol = TLSv1 ... I got server_error: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(No appropriate protocol (protocol is disabled or cipher suites are inappropriate)), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb I can't switch to something better on server side, is it possible to allow weak ciphers/protocols on client side? Thanks in advance, Jiri

migrating standalone engine to selfhosted and upgrade from 4.3 to 4.4 in one step
by Jiří Sléžka 11 Aug '20

11 Aug '20

Hello, I have 4 host cluster managed with standalone engine in version 4.3 and I would like to migrate this standalone engine to 4.4 as hosted engine. I have two new hosts which I would like to use as base for new HE cluster. (new hosts are Intel based, old ones are AMD Opteron based - new cluster will have 4.4 compatibility, old one have to stay at 4.2 compatibility level). I red this https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_… but the question is: Can I migrate and upgrade in one step? Have anybody did that already? If it is not possible what is a suggested approach? Thanks for help Jiri

It is possible to export a vm bigger as 5 TB?

We have a vm with many virtual drives and need to backup as ova file. Since this demands a lot of space I had mounted an nfs directory in the host but get next message after try to export ova: Error whle executing action: Cannot export VM.

The mount persmission is as follow: drwxr-xr-x. 3 vdsm kvm 50 Jul 3 11:47 /mnt/shared2 Any idea how can export this vm?

OVA export creates empty and unusable images
by thomas＠hoberg.net 10 Aug '20

10 Aug '20

I've tested this now in three distinct farms with CentOS7.8 and the latest oVirt 4.3 release: OVA export files only contain an XML header and then lots of zeros where the disk images should be. Where an 'ls -l <vmname>.ova' shows a file about the size of the disk, 'du -h <vmname>.ova' shows mere kilobytes, 'strings <vmname>.ova' dumps the XML and then nothing but repeating zeros until the end of the file. Exporting existing VMs from a CentOS/RHEL 7 farm and importing them after a rebuild on CentOS/RHEL 8 would seem like a safe migration strategy, except when OVA export isn't working. Please treat with priority!

oVirt Hyperconverged question
by Benedetto Vassallo 10 Aug '20

10 Aug '20

Hi all, I am planning to build a 3 nodes hyperconverged system with oVirt, but I have a question. After having the system up and running with 3 nodes (compute and storage), if I need some extra compute power can I add some other "compute" (with no storage) nodes as glusterfs clients to enhance the total compute power of the cluster and using the actual storage? Thank you and Best Regards. -- Benedetto Vassallo Responsabile U.O.
