Q: oVirt and NFS / GlusterFS High-Availability File Sync Algorithm
by Andrei V 22 Dec '17

22 Dec '17

Hi, I would like to ask how (almost) high-availability file sync algorithm works with very simple setup: 2-node (1 main and another backup) + engine on separate PC; each node - Xeon server with RAID L5 for data domain. With GlusterFS copy of each VM disk(s) is being stored on each node data domain and kept up-to-date by GlusterFS sync process automatically. How this works if data domains are on NFS data domains / volumes ? My current setup is really simple, and don't need to be complicated any further. 1st (main) node runs all the time, 2nd (backup) activated only if 1st suffer for example a hardware failure. Anyway, both data domains linked to 2 nodes must be kept fully synced. Right now I finished setup only of 1st node (with CentOS 7, not oVirt node appliance which wipes out all custom software changes upon upgrade). Node data domain runs on GlusterFS. Upon finishing setup of 2nd node (with GlusterFS) they will be joined as Replica 2, and all VMs will be marked as highly available. Since during normal operation all VM disks are being active only on one node, and synced to 2nd (backup), I hope to avoid GlusterFS split brain issue. Please correct me if I'm wrong here. Quite possible I don't entirely understand all underlying algorithms. Thanks in advance Andrei

missing vm in vm portal in statefull pool
by Роман Черкалин 21 Dec '17

21 Dec '17

Hi all, On ovirt 4.2 I make two pools 10 and 20 VMs, 1 vm for each user, and when overall number of vm more than 15 or so, on user login and start, VM has assigned but never appears in vm portal, if try to start again this message will be displayed: "START_POOL failed [Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., Cannot attach VM to VM-Pool. VM-Pool is already attached to a User., User is already attached to maximum number of VMs from this VM-Pool.]". Say if create one pool with 20 VM all happen again. Maybe I'm missing something? With regards, Roman Cherkalin

Virtualized server & oVirt Node on different subnets
by andreil1 19 Dec '17

19 Dec '17

Hi, I have oVirt node running on internal network, address range 192.168.0.x, and need to install virtualized server on DMZ zone 192.168.1.x. Server has several NICs. DMZ NIC will be connected directly to router with firewall. What is the best solution ? 1) Undefine one NIC on CentOS host / node, and assign IP on virtualized server in passthrough mode. 2) Create 2nd oVirtmgmt bridge and link it to NIC on DMZ (if thats possible at all). Thanks in advance. Andrei

Host has not default route
by Roberto Nunin 19 Dec '17

19 Dec '17

Hi all I'm doing further tests deploying from scratch, with the same hardware, one Gluster based hyperconverged LAB. I'm deploying ovirt-node'ng with ISO image: ovirt-node-ng-installer-ovirt-4.2-pre-2017121416. All the process works fine, no more hangs when HE deploy is at the end. Hosts 2 and 3 now can be imported (insted to be added). Storage main domain is added and HE storage automatically imported. One issue: Host 2 and 3 show me: Host has no default route In Host> General tab. Moreover I'm not able to migrate HE, even if the hosted-engine --vm-status looks good, like in the attachment. Could the issue of "Host has no default route" blocking migrations ? Hosts are online, all of three. How to work around the "Host has no default route" message ? I've seen a bug, 1477589, but no solution, till now. Any hints ? -- Roberto Nunin

Ovirt with Hosted Engine and 4 Hosts
by Gabriel Stein 19 Dec '17

19 Dec '17

Hi all, I know, that oVirt with Hosted Engine requires a replica 3 glusterfs volume, but I'm using 4 nodes and I would like to know if is possible to add it to the glusterfs engine volume. Or should I always use 3, 5 and 7 hosts with hosted-engine? What I'm doing: gluster volume add-brick engine server1:/gluster/engine/brick1 server2:/gluster/engine/brick1 server3:/gluster/engine/brick1 server4:/gluster/engine/brick1 Error: volume add-brick: failed: Incorrect number of bricks supplied 4 with count 3 If I'm using replica 3 will not be possible, but how can I upgrade it? Adding 2 more nodes and upgrade to replica 5? Thanks in Advance! Best Regards Gabriel Stein Gabriel Stein ------------------------------ Gabriel Ferraz Stein Tel.: +49 (0) 170 2881531

Q: oVirt Node Update Wiped my Updates
by Andrei V 19 Dec '17

19 Dec '17

Hi ! I have updated today oVirt node 4.1 via yum, installed from oVirt DVD. Update was a minor version change. Now all software I had installed, including mc, Samba, etc. have been lost. Looks like oVirt node is being updated with whole system 600MB image, not just with rpms (please correct if I'm wrong here). Keeping my manually installed software is crucial, since it has UPS and hardware RAID monitor. Can anyone suggest if this is normal behavior or a single glitch ? So far I found only this instruction for node installation: https://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/ And it uses pre-made DVD ISO, not manual install with RHEL/CentOS DVD and RPMs from yum repository. Thanks in advance for any suggestion(s). Andrei

Self-Hosted engine 4.1.7 unavailable from the outside of the host
by Matteo Capuano 18 Dec '17

18 Dec '17

Hi everyone, my name’s Matteo and I’m a new oVirt user. I’m trying to install the gluster hyperconverged solution in a lab environment following the How-To wrote by Jason Brooks: https://ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-st… Sadly, I cannot understand how to configure the network on the self-hosted engine and I’m unable to make it available from outside the host. As written in the HowTo I created three hosts (ovirt-note 4.1.7) each one with two nics, one for gluster and one for management, the network is a static LAN with FQDN resolvable (also reverse) by a local DNS. Here the details: Gateway: 172.16.1.1 DNS: 172.16.1.12 Host1: 172.16.1.210 (management) – 172.16.2.210 (gluster) Host2: 172.16.1.220 (management) – 172.16.2.220 (gluster) Host3: 172.16.1.230 (management) – 172.16.2.230 (gluster) Engine: 172.16.1.200 When installing the engine I choose to brigde the management’s nic (172.16.1.210) of host1 but, once the installation is completed, I'm unable to reach the engine from the LAN where the hosts are connected. The engine (172.16.1.200) can ping only host1 (172.16.1.210) and only host1 can ping the engine. As far as my network knowledge goes, to make the engine available from the outside of host1 I would need to use a third nic or to use some device to associate the ip and MAC address of the engine’s nic. I’ve looked around over the internet for a solution but every how-to I’ve found follows the same steps of Jason’s. I’ve also already asked for help to Jason. Anyone could help me to solve this issue? Thank you Matteo

How can I get those values, without monitoring all VMs directly? oVirt Version we use: 4.1.1.8-1.el7.centos BR Florian

Option to put host into maintenance after installation of new host
by Florian Schmid 18 Dec '17

18 Dec '17

Hi, would it be possible for future releases to add an option to the add new host tab to put the host in maintenance after installation instead of activating it. The same would be for reinstall. I have the problem now, that all hosts after installation will be activated, but network is not configured yet. Therefore host will be in non operational state and will be rebooted immediately. The only solution I have now is to configure power management after the host has all networks configured. I want to have all my networks as required, because otherwise someone will forget to add all of them and then you have other issues. BR Florian

Reassign ovirtmgmt to a new bond with ansible
by Luca 'remix_tj' Lorenzetto 18 Dec '17

18 Dec '17

Hello, I'm trying to create a playbook for deployment of a new node in my ovirt deployment. I'm using the role ovirt-infra from ovirt-infra-roles 1.1.1. I'm creating a new bond and assigning ovirtmgmt to that bond: This is the value of the variable host_networks printed out by ansible: TASK [host_networks] ********************************************************************************************************************************* ok: [localhost] => { "host_networks": [ { "bond": { "interfaces": [ "enp2s0f0", "enp2s0f1" ], "mode": 1, "name": "bond0" }, "check": true, "name": "ovirt01.intranet.company.it", "networks": [ { "address": "10.5.40.197", "boot_protocol": "static", "gateway": "10.5.43.254", "name": "ovirtmgmt", "prefix": "255.255.252.0" } ], "save": true }, { "bond": { "interfaces": [ "enp2s0f2", "enp2s0f3" ], "mode": 1, "name": "bond1" }, "check": true, "name": "ovirt01.intranet.company.it", "networks": [ { "address": "10.5.160.47", "boot_protocol": "static", "name": "NFS", "netmask": "255.255.252.0" } ], "save": true } ] } When running the playbook i get: Error: Fault reason is "Operation Failed". Fault detail is "[Cannot setup Networks. Network ovirtmgmt is already attached via attachment 3315148d-f669-48b0-9c16-601faaea9ce5. A new attachment cannot be used for the same network, please reuse the existing one.]" How do i reuse the existing attachment? The other network (NFS) has been attached without issues. -- "E' assurdo impiegare gli uomini di intelligenza eccellente per fare calcoli che potrebbero essere affidati a chiunque se si usassero delle macchine" Gottfried Wilhelm von Leibnitz, Filosofo e Matematico (1646-1716) "Internet è la più grande biblioteca del mondo.

Another attempt to fully check deploy of ovirt-node-ng and hoste engine in my lab environment. Ovirt node image used: ovirt-node-ng-installer-ovirt-4.2-pre-2017121215.iso Three HPE Proliant BL680cG7, with local storage (Gluster). Full deploy from scratch, executed two times just to have confirmation. In both cases I had the same condition. Gluster deploy complete without issues. Hosted Engine do not complete, hangs at the end of the process, when HE VM is answering correctly. Imported two additional hosts (now that part works correctly) Added first data domain, ok Imported automatically the hosted-engine data domain Failed to import the Hosted Engine VM is the error that appear in the event log. Attached the HE deploy log and HE engine.log, where are reported all the attempts to import HE VM: 2017-12-14 01:43:38,733+01 ERROR [org.ovirt.engine.core.bll.HostedEngineImporter] (EE-ManagedThreadFactory-engine-Thread-259) [1193f931] Failed importing the Hosted Engine VM 2017-12-14 01:43:38,739+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-259) [1193f931] EVENT_ID: HOSTED_ENGINE_VM_IMPORT_FAILED(10,457), Failed importing the Hosted Engine VM 2017-12-14 01:43:53,703+01 ERROR [org.ovirt.engine.core.bll.HostedEngineImporter] (EE-ManagedThreadFactory-engine-Thread-266) [4d597e01] Failed importing the Hosted Engine VM 2017-12-14 01:44:08,812+01 ERROR [org.ovirt.engine.core.bll.HostedEngineImporter] (EE-ManagedThreadFactory-engine-Thread-273) [5cef57aa] Failed importing the Hosted Engine VM This is the screenshot of the "frozen" phase [image: Immagine incorporata 1] Any hint about find the reason about the failed import ?

about iscsi multipathing
by Nathanaël Blanchet 14 Dec '17

14 Dec '17

Hi all, It should be a good idea not to allow adding a new iscsi multipath profile when hosts don't have an IP address on the selected network... or make unvailable network that don't have IP address in the dialog. Currently, engine allows it without error while it is not effective on the hosts. Should be a RFE, shouldn't be? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Storage Migration issues
by Mark Steele 14 Dec '17

14 Dec '17

Hello, We have begun migrating VM boot disks from one Storage domain to another. Both the storage domains are NFS and both are V3. The Ovirt instance is oVirt Engine Version: 3.5.0.1-1.el6 I am shutting down the VM's prior to migration (not a live migration). When the disks complete their move, I start the VM back up on the original host. The hosts are all running either Ubuntu 14.04 LTS or 16.04 LTS I have experienced the following two issues: - when the VM's come back up, they are not mounting an external NFS mount that is defined in /etc/fstab. The mount can be reinstated manually and survives subsequent reboots - but every VM that has an external NFS mount has this issue after migration - VM's that have a docker instance running no longer respond to web requests on the web server ports that the docker instance is running. Any thoughts on why this would happen would be greatly appreciated.
