4.3.x upgrade and issues with OVN
by Charles Weber 22 Apr '19

22 Apr '19

Hi everyone, We have had a pair of Ovirt clusters at work, starting with the 3.x. I replaced last year with 4.x cluster on new machines. 4.2 worked great, but when I upgraded to 4.3.2 and now .3 I immediately ran into host networking issues resulting in hung or unable totally to migrate VMs. Configuration notes: 1. I use commercial star.x.x.x SSL cert on engine installed per Ovirt.org instructions 2. I have 2 untagged NICs assigned to ovirtmgmt and Public, both on the same IP range network. I also have another set of VLANs tagged on various NICs. 1 cluster uses HP blades with lots of NICs, the other uses supermicro 1Us with only 2 NICs. 3. I upgraded both engines and hosts to 4.3.2 from 4.2.8. I started seeing hung migrations cleared by restarting vdsm. 4. All computers involved run current CentOS 7.6 5. Both clusters use iscsi on dedicated tagged storage VLAN, seems fine. 6. I upgraded 1 engine and 1 host to 4.3.3 and things got worse. I have not updated any hosts or the second engine since. 7. The 4 hosts on the 4.3.3 engine now have out of sync error that refuses to clear for my Public network. 8. 2 OV 4.3.2 nodes had the following errors with 2 ovn ports. Here is example, perhaps related to the genev_sys_6081 error. ovn-d6eaa1-0: attempting to add tunnel port with same config as port 'ovn-f0f789-0' (::->137.187.160.13 ovn-877214-0: attempting to add tunnel port with same config as port 'ovn-483528-0' 9. I deleted and uninstalled all ovirt related rpms on one node, then did clean node install using latest 4.3 release. Same errors. 10. I downloaded latest node iso, installed on same host, upgraded to to 4.3.3.1 node and joined cluster. The node installation has no errors and can migrate to my other hosts. All networks are in sync. The migration hangs. Restarting VDSMD clears the hung migration. 11. None of the other hosts can migrate VMs to the new node. Here are excerpts from 3.2 node on 3.3 engine log file.

Hi Michael, I know how you feel abiut VDO. I wass in the same boat until I starrted using systemd's mount units.Since then I do not have any issues. For now try the following: Boot 1 host via rescue dvd , chroot into the system and install the vdo and kvdo packages (maybe reinstall is more correct) . Once then, try to run the vdo service (still in chroot) and try to make it work. Then, just rebuild the initramfs (dracut -f -k kernel-version) and reboot. Check if your VDO, bricks and Gluster are operational again. If yes, do the other nodes. Once done - run 'gluster volume heal my-volume full' (replace my-volume with actual name). This will force gluster to sync all bricks. P.S.: Now, I'm using gluster snapshot for recovery between engine upgrades (HostedEngine is stopped while makking the snapahot).

Issues post-upgrade from 4.2.8 to 4.3.2
by Vrgotic, Marko 21 Apr '19

21 Apr '19

Dear oVirt team, We have 3 Hosts HA Cluster with SHE engine. Storage is NetApp. Recently we have executed an upgrade from 4.2.8 to 4.3.2. Since then we are seeing strange behavior when trying to put Hosts to Maintenance or manually Migrate VMs between Hosts. The most repeated WARN/ERROR I am observing is following: The UI is constantly throwing an exception when trying to put HA host to maintenance or increase the SPM level. The repeated log line from engine.log I see, with regards or failing to migrate all hosts is: 2019-04-18 13:05:30,760Z WARN [org.ovirt.engine.core.bll.MigrateVmCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-83) [63d33dd1] Validation of action 'MigrateVm' failed for user SYSTEM.

VM Snapshots not erasable and not bootable
by Jonathan Baecker 21 Apr '19

21 Apr '19

Hello, I make automatically backups of my VMs and last night there was making some new one. But somehow ovirt could not delete the snapshots anymore, in the log it show that it tried the hole day to delete them but they had to wait until the merge command was done. In the evening the host was totally crashed and started again. Now I can not delete the snapshots manually and I can also not start the VMs anymore. In the web interface I get the message: VM timetrack is down with error. Exit message: Bad volume specification {'address': {'bus': '0', 'controller': '0', 'type': 'drive', 'target': '0', 'unit': '0'}, 'serial': 'fd3b80fd-49ad-44ac-9efd-1328300582cd', 'index': 0, 'iface': 'scsi', 'apparentsize': '1572864', 'specParams': {}, 'cache': 'none', 'imageID': 'fd3b80fd-49ad-44ac-9efd-1328300582cd', 'truesize': '229888', 'type': 'disk', 'domainID': '9c3f06cf-7475-448e-819b-f4f52fa7d782', 'reqsize': '0', 'format': 'cow', 'poolID': '59ef3a18-002f-02d1-0220-000000000124', 'device': 'disk', 'path': '/rhev/data-center/59ef3a18-002f-02d1-0220-000000000124/9c3f06cf-7475-448e-819b-f4f52fa7d782/images/fd3b80fd-49ad-44ac-9efd-1328300582cd/47c0f42e-8bda-4e3f-8337-870899238788', 'propagateErrors': 'off', 'name': 'sda', 'bootOrder': '1', 'volumeID': '47c0f42e-8bda-4e3f-8337-870899238788', 'diskType': 'file', 'alias': 'ua-fd3b80fd-49ad-44ac-9efd-1328300582cd', 'discard': False}. When I check the path permission is correct and there are also files in it. Is there any ways to fix that? Or to prevent this issue in the future? In the attachment I send also the engine.log Regards Jonathan

Re: Ovirt gluster arbiter within hosted VM

With GlusterD2 , you can use thin arbiter - which can be deployed in the cloud. Do not try to setup regular arbiter far away from the data bicks or yoir performance will be awful.

As long as the VM is not hosted by those 2 hyperconverged nodes - there should be no problem. Another option is a small machine with a single SSD. I'm using Lenovo Tiny M-series as an arbiter.

Replica 3 distribute-replicated - data placement and fault tolerance
by Leo David 20 Apr '19

20 Apr '19

Hello Everyone, I did some fio performance tests on a particular vm and I have noticed things that I do not understand regarding how data is placed along the bricks. I am sure this is a lack of knowledge, but I would really appreciate any help in understanding this, I did a bit of research on the internet, but just could't find something relevant. I have one replica 3 distributed-replicated arbitrated volume, across 18 bricks ( 9 nodes, 2 jbods per node ). The volume was created as: node1 - brick1, node-2, brick1,.....node9-brick1, node1 - brick2, node-2, brick2,.....node9-brick2 As far as i've understood, under the hood there are sets of 3 times replicated data ( subvolumes ) which are assigned to the first 3 bricks, next set of replicated data to the next set of 3 bricks, and so on.. Now, I have this testing vm runign one node one. When I've started the fio test, i've noticed incresed gluster traffic from node 1 to node2,4 and 5 So I assumed that the vm disk is data resides on a subvolume allocated to bricks from these hosts. Then I have migrated the vm on node 2, and did the same test. Now the increased treffic is generated from node2 to node1, 4, and 5.. What I do not understand is: - why gluster client ( ovirt host ) is sending data to 3 bricks if the volume is arbitrated - shouldn't it send only to 2 of them ? - why are there 4 brick implicated in this subvolume - what would it be the fault tolerance level in this setup ,ie: how many hosts can I take down and still having the volume serving IO requests; can they be random ? I am sorry for my lack of knowledge, I am just trying to understand what is happening so I can deploy a decent proper setup of an hci environment. Thank you, Leo -- Best regards, Leo David
