How to delete/detach a disk from online VM ?
by morgan cox 22 Mar '23

22 Mar '23

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 21 Mar '23

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 * hosts: Rocky Linux release 8.7 Thanks engine: 4.5.4-1.el8 hosts: Rocky Linux release 8.7

Gluster Geo-Replication session not visible in oVirt Manager UI
by simon＠justconnect.ie 20 Mar '23

20 Mar '23

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

4.5.2 Create Additional Gluster Logical Volumes fails
by simon＠justconnect.ie 20 Mar '23

Hi, In 4.4 adding additional gluster volumes was a simple ansible task (or via cockpit). With 4.5.2 I tried to add new volumes but the logic has changed/broken. Here's the error I am getting: TASK [gluster.infra/roles/backend_setup : Create volume groups] ******************************************************************************************************************************** failed: [bdtovirthcidmz02-strg.mydomain.com] (item={'key': 'gluster_vg_sda', 'value': [{'vgname': 'gluster_vg_sda', 'pvname': '/dev/sda'}]}) => {"ansible_loop_var": "item", "changed": true, "cmd": ["vgcreate", "--dataalignment", "2048K", "-s", "2048K", "gluster_vg_sda", "/dev/sda"], "delta": "0:00:00.010442", "end": "2022-11-10 13:11:16.717772", "item": {"key": "gluster_vg_sda", "value": [{"pvname": "/dev/sda", "vgname": "gluster_vg_sda"}]}, "msg": "non-zero return code", "rc": 3, "start": "2022-11-10 13:11:16.707330", "stderr": " Configuration setting \"filter\" invalid.

oVirt On Rocky 8.x - Upgrade To Rocky 9.1
by Matthew J Black 20 Mar '23

20 Mar '23

Hi All, Sorry if this was mentioned previously (I obviously missed it if it was) but can we upgrade an oVirt (latest version) Host/Cluster and/or the oVirt Engine VM from Rocky Linux (RHEL) v8.6/8.7 to v9.1 (yet), and if so, what is / where can I find the procedure to do this - ie is there anything "special" that needs to be done because of oVirt, or can we just do a "simple" v8.x +> v9.1 upgrade? Thanks in advance Cheers Dulux-Oz

ovirt and network outages
by Fedele Stabile 20 Mar '23

20 Mar '23

Hi, I would like to know if it is possible to configure oVirt so as not to be affected by internet connection loss. I have three ovirt hosts and together with the switch that connects them they are powered by a UPS. Currently, when I have an internet outage, the oVirt hosts get misaligned and the VMs shut down.
