oVirt 4.2 Upgrade
by KSNull Zero 13 May '18

13 May '18

Hello! Let's assume that we have 2 clusters in a shared Datacenter running version 4.1. Is it possible to have one cluster running v4.2 and another one running v4.1 in the same Datacenter (what version will it be, by the way ?) during transitioning to oVirt 4.2 ? Thank you.

Is PostgreSQL 9.5 required now as of oVirt 4.2?
by Lacey Powers 13 May '18

13 May '18

Hi All, I have a setup of oVirt on 4.1 that has been working brilliantly for over a year, serving the production workloads at my dayjob without complaint. Originally, I had set it up with a custom PostgreSQL version, 9.6, from the PGDG repositories, since the suggested 9.2 was already quite old, and it allowed me to keep consistent versions of PostgreSQL across all the infrastructure I have. Now that I am trying to upgrade to oVirt 4.2, when I run engine-setup per the directions in the release notes documentation, engine-setup insists on PostgreSQL 9.5 from Software Collections, comparing the postgresql versions and then aborting. I don't see a way to tell it that I have a different running version of PostgreSQL that's greater than 9.5 already. Does this mean that no other versions than 9.5 are supported, and I need to downgrade and use the Software Collections version exclusively? Or is there a custom setting that I am missing that will enable me to continue using the 9.6 install I already have. Thank you for your time. Best, Lacey

Hosted Engine dependency issue

Hello, I am new to Ovirt (and linux) , I successfully installed a working hosted engine twice but am now running into a dependency issue. I keep getting the below message: Error: Package: cockpit-storaged-160-1.el7.centos.noarch (extras) Requires: storaged-iscsi >= 2.1.1 Available: storaged-iscsi-2.5.2-2.el7.x86_64 (ovirt-4.2-centos-ovirt42) storaged-iscsi = 2.5.2-2.el7 Available: storaged-iscsi-2.5.2-4.el7.x86_64 (extras) storaged-iscsi = 2.5.2-4.el7 Error: Package: cockpit-storaged-160-1.el7.centos.noarch (extras) Requires: storaged >= 2.1.1 Available: storaged-2.5.2-2.el7.x86_64 (ovirt-4.2-centos-ovirt42) storaged = 2.5.2-2.el7 Available: storaged-2.5.2-4.el7.x86_64 (extras) storaged = 2.5.2-4.el7 Error: Package: cockpit-storaged-160-1.el7.centos.noarch (extras) Requires: storaged-lvm2 >= 2.1.1 Available: storaged-lvm2-2.5.2-2.el7.x86_64 (ovirt-4.2-centos-ovirt42) storaged-lvm2 = 2.5.2-2.el7 Available: storaged-lvm2-2.5.2-4.el7.x86_64 (extras) storaged-lvm2 = 2.5.2-4.el7 I wiped the machine and tried again with no luck.

ONN v4.2.3 Hosted Engine Deployment - Auto addition of Gluster Hosts
by glenn.farmer＠netfortris.com 12 May '18

12 May '18

The new Ovirt Node installation script in v4.2.3 automatically adds the gluster hosts after initial hosted engine setup. This caused major problems as I had used different FQDNs on a different VLAN to initially setup my gluster nodes [to isolate storage traffic] - but then put them onto the "ovirtmgmt" network. Because they were gluster nodes - I could not remove them from the ovirtmgmt network to re-install on the proper management VLAN. I recommend removing the auto-installation of the other gluster nodes - or at least provide an option to decline the automatic addition of the other nodes.

Does the dependency for the various storaged packages need to be updated to instead require udisks2?

gluster dispersed volume provisioning
by josip＠section7.eu 11 May '18

11 May '18

Hi, have a quick question regarding ovirt UI and provisioning of gluster volumes. I've found an old thread - https://lists.ovirt.org/pipermail/users/2015-February/064602.html - where it's said that creating dispersed volumes is not supported but that it will be in the next release. Is there any update on when will it be supported? Thanks
