Update oVirt Node to 4.5.4 fails do to disk full (with urandom)
by Sven Jansen
Hi,
i try to update my oVirt Nodes from 4.5.3 to 4.5.4 but it always fails on my hosts. Watching the rpm install process i see that the rpm is building the boot image/bank and /var/tmp filling up quickly. Looking deeper into this folders i see that there is a dracut folder created by the update process that contains a urandom file with the size of all available space in /var/tmp.
[root@ovnode01 dev]# df -h

For me it looks like that imgbase (or whatever build this images) copies /dev/urandom into the new image, as expected this is not possible. Anyone know an workaround for this issue?

HostedEngine: Unable to add virtual disk
by ziyi Liu
I want to add a disk to HostedEngine, and the following error occurs when adding a disk in the web ui
HostedEngine:
Unable to add virtual disk. The engine is not managing this virtual machine.
Does HostedEngine need to use vdms to add disks?
Is it the following operation
1. Set managed engine maintenance mode to global
2. Close HostedEngine
3. Extend the disk vdsm-client Volume extendSize
4. start vm
5. Use fdisk to partition and expand

If the latest outage was not long ago, you could still find some
preliminary and useful information inside /var/log/ovirt-engine/engine.log
of the engine
In general, for all oVirt related log files you can refer to this url:
https://www.ovirt.org/documentation/administration_guide/#chap-Log_Files
some of them are also rotated

How to delete/detach a disk from online VM ?
by morgan cox
Hello.
Is it possible to remove a (unmounted, unused) disk from a VM when online?
I tried via the UI and I get 'Error while executing action: Cannot remove Virtual Disk. At least one of the VMs is not down.'
I know you can with standard KVM/Libvirt/virt-manager - is there any way I can remove a disk from a VM whilst it is online in Ovirt ?
Thanks

I can't enable cinderlib
by fsayd＠derecho.uncu.edu.ar
Hello:
I am trying to deploy a 4.5 cluster with 3 hosts that also provides Ceph
storage. I am running the engine in a standalone host (No hosted
engine).
I followed the steps to enable cinderlib
(https://access.redhat.com/solutions/5605141) but the managed domain
option doesn't show in the add storage domain dialog.
I don't know what I am doing wrong
Do I need to add a primary storage domain (iSCSI, NFS, etc) in order to
add a Ceph domain??
* engine: 4.5.4-1.el8

Gluster Geo-Replication session not visible in oVirt Manager UI
by simon＠justconnect.ie
I have previously created Gluster geo-replicated sessions from the command line on 4.4.5. These sessions appear in the 'Geo-Replication' Tab of the Gluster Volume on the Master.
I've just built 2 new oVirt clusters 4.5.3.2 and configured a geo-replicated session. The session doesn't appear in the WebUI but appears to be working when checked from the command line.
Any ideas anyone please?
Regards
Simon
