add gluster cluster to deployed cluster
by p.staniforth＠leedsbeckett.ac.uk 11 Sep '18

Hello People, I have a 3 node cluster this just has virt service deployed, how would I add gluster service to this. We have installed 2 extra disks in each node and they are running oVirt Node 4.2.5.1 After we have a gluster service running how easy would it be to migrate an existing engine to Self Hosted Engine? Thanks, Paul S.

Clean stuck VM from ovirt dashboard
by Alex K 10 Sep '18

10 Sep '18

Hi all, I have a failed clone of a VM which led to the clone being listed as a VM with state "Image locked", as if the clone is still continuing. No tasks are being shown and for sure the clone is not continuing. Also there are not disk images listed for this VM instance at the disks tab. How can i remove this fake VM from the GUI. There might be some steps I can do in the engine DB to make the engine forget about this VM. I a running ovirt 4.1.9. (I know not the latest, though this will be for some time until we prepare to move to 4.2.X) Thanx, Alex

hosted-engine --check-liveliness returns "Hosted Engine is not up!" for host other cluster
by omprakashp＠cdac.in 10 Sep '18

10 Sep '18

Hi , I am just getting started with Ovirt. I have setup 3 Ovirt-Nodes(all on physical host) and deployed self hosted engine with iscsi storage on one of the host. On engine ui, i have create two Clusters(C1, C2) and Engine is running in C1. While executing "hosted-engine --check-liveliness" on hosts in C2 cluster, it says "Hosted Engine is not up!". Is this an issue? Or this means i have to deploy hosted engine in C2 cluster too.

Moving all disks to new storage domain
by Simon Vincent 10 Sep '18

10 Sep '18

I need to decommission an old SAN so I have connected a new one into ovirt as a new storage domain. I would like to use a python script to move all disks/snapshots/everything over to the new storage domain but I am having some problems. I am trying to search for all VMs using a particular storage domain but this is not working how I would like. The code I am using is: vms = vms_service.list(search='Storage=team-data') However this is returning VMs which are using storage domains 'team-data' and 'team-data2'. Is this a bug or is there another way to return vms from just 'team-data'? My script so far is: connection = sdk.Connection( url=ovaddress, username=username, password=password, insecure=True ) system_service = connection.system_service() vms_service = system_service.vms_service() disks_service = connection.system_service().disks_service() vms = vms_service.list(search='Storage=team-data') sds_service = connection.system_service().storage_domains_service() dest_sd = sds_service.list(search='name=team-data2') if len(dest_sd)!=1: exit() dest_sd=dest_sd[0] for vm in vms: print (vm.name) vm_service = vms_service.vm_service(vm.id) disk_attachments = vm_service.disk_attachments_service().list() for disk_attachment in disk_attachments: disk = connection.follow_link(disk_attachment.disk) print (" disk: " + disk.name) disk_service = disks_service.disk_service(disk.id) disk_service.move(storage_domain=dest_sd) while True: print("Waiting for movement to complete ...") time.sleep(10) disk = disk_service.get() if disk.status == types.DiskStatus.OK: break connection.close()

Hi Sahina, https://ovirt.org/develop/release-management/features/gluster/gluster-geo-r… Unfortunately, there isn't info on how to set this up. Can you share with us any tips or info needed to do geo-rep between 2 sites? I also read an article that says geo-rep between 3 sites is possible? Thanks, Femi

Hi, Last night we have an incident of a failed host. Engine issued a fence but did not restart the vms running on that node on other operational hosts. I'd like to know if this is normal or I can tune it somehow. Here are some relevant logs from engine: 2018-09-05 03:00:51,496+03 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (EE-ManagedThreadFactory-engine-Thread-827644) [] Host 'v3' is not responding.
