Re: oVirt Open Source Backup solution?
by Strahil 14 May '19

Another option is to create a snapshot, backup the snapahot and merge the disks (delete the snapshot actually). Sadly that option doesn't work with Databases, as you might inyerrupt a transaction and leave the DB in inconsistent state.

I am having hard time installing OVIrt. Gluster deployment for the single node sometimes work, but host engine deployment never works. Any one has suggestion on which release of OVirt to use as a beginner.

Permission Problem for admin portal
by s.gay＠ovea.com 13 May '19

13 May '19

Hello, I'm using the lastest ovirt release. I would like to add a cluster permission for a user. This user should only see this cluster and not other information or other cluster I've create a new user in internal or external When the ClusterAdmin role is added in the permission tab of a cluster, the user can access the entire infrastructure through the user portal or administrator portal. It can modify other VMs, ... I checked the other cluster and the user does not appear in the permissions When I add the UserRole role to the cluster and remove the ClusterAdmin role, it sees only the VMs in the cluster in the user portal When the user creating a VM, he can see all the cluster in the drop-down window for cluster selection It's possible to add only a cluster permission for users ? Thanks

HostedEngine migration from ovirt1:/engine to gluster1:/engine (new ip)
by Strahil Nikolov 13 May '19

13 May '19

Hello Community, I have added new interfaces and bonded them in order to split storage from oVirt traffic and I have one last issue. In Storage -> Storage Domains , I have the "hosted_storage" domain that is pointing to the old "ovirt1.localdomain:/engine" instead of "gluster1:/engine". I have managed to reconfigure the ha agent to bring the new storage , but it seems the engine mounts the old gluster path and this causes problem with the ha agent . How can I edit the "hosted_storage" in a safe manner to point to "gluster1:/engine" and mount options of "backup-volfile-servers=gluster2:ovirt3". Should I edit the DB ? P.S.: My google skills did not show any results on this topic and thus I'm raising it to the mail list.Thanks in advance. Best Regards,Strahil Nikolov

Upgrade success story (4.3.0->4.3.3)
by Juhani Rautiainen 13 May '19

13 May '19

Hi! Just wanted to let you know that I succesfully upgrade our cluster to 4.3.3 (FC SAN based system and no Gluster). I postponed upgrade a lot because of the difficulties I had when upgrading from 4.2.8->4.3.0. This time Hosted Engine upgrade went without any problems. The first node also upgraded itself from admin UI without any problems. The second node was different story. I couldn't upgrade it because yum complained about missing packages. This was mysterious as I just had upgraded the other node. I bypassed this by taking ovirt-4.3 repos from other node since diffing files gave results that they differed. After that node upgraded from UI but went missing after reboot. Contacting it via ILO I found out that it had turned to DHCP again (which it never should do). Somehow settings in VDSM persistent settings were still wrong and pointing to DHCP (it has always been in fixed address). Fixed this by hand by using vdsm persistent settings from the running node. Now the node reboots reliably. Anyway thanks for all the good work oVirt people put in. Small problems here and there but it's getting better by the release. -Juhani

Node losing management network address?
by Juhani Rautiainen 13 May '19

13 May '19

Hi! I had weird occurence in my two node ovirt cluster today (I have HE). I noticed that one node had ovirtmgmt network unsynchronized. I tried to resynchronize it. This led the node being rebooted by HP ILO. After reboot the node came up with DHCP address. Tried to change it back by fixing ifcfg-ovirtmgmt to original static address. It reverter back to DHCP if I tried the resync the network. I decided to remove HE from the node in order to remove the node in order to be able to add it back. After I started HE removal, address popped back to static address. I did upgrade which was pending on node and after reboot it came back with DHCP address again. After this I removed the node from the cluster, added it back and now it seems to work. I'm just wondering how I prevent this from happening again? How this unsync situation happens for instance and why it decides that DHCP is the way to go? -Juhani

VMs import over slow 1gig interface instead of fast 10gig interface?
by Jacob Green 13 May '19

13 May '19

Ok, so I want to try and more thoroughly explain my situation. I want to better understand what is happening, and if there is a way to force import over the faster connection. Today I have two Ovirt environments, one on 4.1 and one on 4.2, on the new environment we have migrated to new VLANs for Management and Data. The export domain is a NFS domain hosted on a Trunas device that has an ip address of X.X.12.100. Our host has multiple Ethernet connections, one Bonded 20Gigabit interface. That is where we have the ovirtmgmt profile. And a secondary 1 Gigabit interface that we call our VLAN12 profile or server VLAN. *The problem.... *When importing a VM from the export domain, the import is happening over the 1Gigabit interface on the VLAN12 profile. Instead of the 20gigabit Bonded interface on VLAN 100. *My understanding.... *So I probably just misunderstand how this works, but here is what I thought should happen, in the *Setup Host Network* screen for this host I have the ovirtmgmt on VLAN100 with the bonded 20Gigabit interface performing the following. "*Management, Display, Migration, VM and Default Route*." Then I have the secondary 1 Gigabit interface just doing "*VM*" on VLAN12. What I thought should happen is that anything Migration related "*/Includes importing from export domain?/*" should happen on the Migration interface, which in my case is the ovritmgmt interface on VLAN100. I have also confirmed that I can ping from the VLAN100 ovirtmgmt interface to the storage on VLAN12. So there is connectivity from that interface to the storage. What I am trying to figure out is there a way to force it to do imports over the 20Gigabit interface that resides on VLAN100 instead of the slower VLAN12 interface, that is just there for general VM connectivity. Thank you for any advice or guidance on this matter. -- Jacob Green Systems Admin American Alloy Steel

Re: OvfUpdateIntervalInMinutes restored to original value too early?
by Andreas Elvers 12 May '19

12 May '19

I suppose the /var/log/ovirt-hosted-engine-setup/engine-logs-2019-05-10T16:16:14Z/ovirt-engine/engine.log is the bootstrap engine log. It is attached. The bootstrap engine looks quite ok when glancing through the dashboard, datacenter, storage domains,… Although there are two old hosted storage domains.

Upgrade engine to 4.3.3 or setup a new engine
by Magnus Isaksson 12 May '19

12 May '19

Hello all I'm having trouble upgrading my engine to 4.3.3 from 4.2.8 The upgrade goes well, no errors but webgui wont load, it just says "waiting for engine" I have tried to set up a new machine with engine and import the DB from the old(after upgrade) still the same problem. So after quite a few tries i gave up and set up a fresh new engine 4.3.3 But can i move/migrate the hosts with running VM:s in to the new engine? In vmware vcenter it is just to add the host and all VM:s and stuff comes over, but im guessing from what ive read that it is not that simple with ovirt. Or how should i solve this? //Magnus

HostedEngine cleaned up
by Sakhi Hadebe 12 May '19

12 May '19

Hi, We have a situation where the HostedEngine was cleaned up and the VMs are no longer running. Looking at the logs we can see the drive files as: 2019-03-26T07:42:46.915838Z qemu-kvm: -drive file=/rhev/data-center/mnt/glusterSD/glustermount.goku:_vmstore/9f8ef3f6-53f2-4b02-8a6b-e171b000b420/images/b2b872cd-b468-4f14-ae20-555ed823e84b/76ed4113-51b6-44fd-a3cd-3bd64bf93685,format=qcow2,if=none,id=drive-ua-b2b872cd-b468-4f14-ae20-555ed823e84b,serial=b2b872cd-b468-4f14-ae20-555ed823e84b,werror=stop,rerror=stop,cache=none,aio=native: 'serial' is deprecated, please use the corresponding option of '-device' instead I assume this is the disk was writing to before it went down. Trying to list the file gives an error and the file is not there; ls -l /rhev/data-center/mnt/glusterSD/glustermount.goku:_vmstore/9f8ef3f6-53f2-4b02-8a6b-e171b000b420/images/b2b872cd-b468-4f14-ae20-555ed823e84b/76ed4113-51b6-44fd-a3cd-3bd64bf93685 Is there a way we can recover the VM's disk images ? NOTE: No HostedEngine backups -- Regards, Sakhi Hadebe
