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

vm operation after host fence
by Kapetanakis Giannis 06 Sep '18

06 Sep '18

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.

OVN and impact of missing connectivity with OVN Provider/Central
by Gianluca Cecchi 05 Sep '18

05 Sep '18

Hello, I have VM1 and VM2 with their vnics on OVN. They are running on the same host. Suppose this host (and so its OVN Controller) looses connectivity with the OVN Provider (that in my case runs on oVirt engine, that is an external server). Is it correct/expected that VM1 looses connectivity with VM2 until fixed? So, in other words, is the OVN Provider a sort of single point of failure (eg if I restart enigine in my case)? Thanks, Gianluca
