Next Gluster Updates?
by Robert O'Kane 29 Aug '18

29 Aug '18

I had a bug request in Bugzilla for Gluster being killed due to a memory leak. The Gluster People say it is fixed in gluster-3.12.13 When will Ovirt have this update? I am getting tired of having to restart my hypervisors every week or so... I currently have ovirt-release42-4.2.5.1-1.el7.noarch and yum check-updates shows me no new gluster versions.....(still 3.12.11) Cheers, Robert O'Kane -- Robert O'Kane Systems Administrator Kunsthochschule für Medien Köln Peter-Welter-Platz 2 50676 Köln fon: +49(221)20189-223 fax: +49(221)20189-49223

Guide for setting up GlusterFS geo-replication?
by Jayme 29 Aug '18

29 Aug '18

Is there an updated guide for setting up GlusterFS geo-replication? What I am interested in is having another oVirt setup on a separate server with glusterFS volume replicated to it. If my primary cluster went down I would be able to start important VMs on the secondary oVirt build until I'm able to repair the main cluster. In oVirt 4.2.5 clicking geo-replication > new in the volume GUI produces no results. Nothing happens when I click it (using multiple browsers). And under storage domains clicking remote data-sync -> setup produces a popup but just has a loading icon in the middle and never completes loading. Why are neither of these two features working for me?

Turn Off Email Alerts
by Douglas Duckworth 28 Aug '18

28 Aug '18

Hi How do I turn off hosted engine alerts? We are in a testing phase so these are not needed. I have disabled postfix on all hosts as well as stopped the ovirt notification daemon on the hosted engine. I kept it running while putting /dev/null in /usr/share/ovirt-engine/services/ovirt-engine-notifier/ovirt-engine-notifier.conf for mail server. Yet I still get alerts for every thing done such as putting hosts in maintenance mode. Very confusing.

mask or disabled lldpad service
by Klaas Demter 28 Aug '18

28 Aug '18

Hi, I have a QLogic Corp. QLogic 2x1GE+2x10GE QL41162HMRJ CNA network card. This network card comes with it's own lldp implementation inside their management firmware. Running two lldp agents seems to create several issues (http://lists.us.dell.com/pipermail/linux-poweredge/2018-July/051860.html) The QLogic engineers said I need to disable lldpad in the operating system. This leads me here, what is lldp actually used for within ovirt? If it is actually needed how could I deal with a card that does not support lldpad but rather has it's own implementation? Greetings Klaas

VDO + HCI = failed reboots
by Donny Davis 28 Aug '18

28 Aug '18

I just spun up the latest and greatest ovirt has to offer, and I am building out an HCI cluster. The deployment went wonderfully. I had dns setup for everything, and it just worked. Great job team! I just wanted to add in something i noticed after rebooting the nodes. The gluster service, and volumes would not come back up after rebooting. I found that there needs to be an entry in the fstab for the gluster logical volumes to tell them to start the vdo service. So without this, the node will fail to boot if you are using vdo. inode64,noatime,nodiratime,discard,x-systemd.requires=vdo.service the defaults are this inode64,noatime,nodiratime Hopefully it helps someone else :) Cheers
