Creating Thin-provisioned disks on a gluster volume
by Dmitry Filonov 08 May '19

08 May '19

Hi - We want to migrate our aging oVirt cluster to a new one and decided to go for the hyperconverged setup with Gluster and hosted engine. Got 3 new machines, set everything up, did a test VM migration and were almost ready to do final migration of our VMs when I notice one really weird thing. When migrating VMs from NFS storage onto Gluster they stay thin provisioned. But if I try creating new disk image from the oVirt GUI - I get preallocated volume. No matter if I select "thin provision" or "Preallocated" I always get preallocated volume created. The engine.log says - 2019-05-07 17:14:20,562-04 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.CreateImageVDSCommand] (default task-20) [bbd94792-2f86-44eb-9334-807dd44d0742] START, CreateImageVDSCommand( CreateImageVDSCommandParameters:{storagePoolId='43550c2c-7100-11e9-9b45-00163e4babb7', ignoreFailoverLimit='false', storageDomainId='1de2f7ac-ee52-43fb-89ac-f86b62f73b9a', imageGroupId='86c5c5e9-6533-4caf-a5a5-401556a5059a', imageSizeInBytes='21474836480', volumeFormat='RAW', newImageId='470b8035-9380-408d-a644-96e8d74c4e8e',* imageType='Preallocated', *newImageDescription='{"DiskAlias":"test","DiskDescription":""}', imageInitialSizeInBytes='0'}), log id: 228ddfd5 Is there any tweak I didn't notice to make things actually what it suppose to be doing? oVirt 4.3.3.5-1.el7 glusterfs 5.5-1.el7 CentOS Linux release 7.6.1810 Thank you! -- Dmitry Filonov Linux Administrator SBGrid Core | Harvard Medical School 250 Longwood Ave, SGM-114 Boston, MA 02115

Hosted engine restore went very wrong
by Andreas Elvers 07 May '19

07 May '19

I really feel like an idiot. I tried to move our hosted engine from our Default datacenter to our Ceph Datacenter. I ran intro problems which were correctly addressed. see: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/ZFCLFWRN6XR6KM… It was in case a race condition. I was able to bring back the engine to our Default Cluster. And then I tried to do the move again to our Ceph Datacenter. I got the error "The target Data Center does not contain the Virtual Disk" twice yesterday. Because it was late, I decided to do it in the next morning. I did a new backup from the engine. Copied it over to the new node of the Ceph Datacenter and started the hosted-engine --deploy. But I FORGET TO SHUTDOWN the other engine! Oh man. The deploy script errored out with: [ ERROR ] fatal: [localhost]: FAILED! => {"censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result", "changed": false} [ ERROR ] fatal: [localhost -> engine.infra.solutions.work]: FAILED! => {"changed": false, "msg": "There was a failure deploying the engine on the local engine VM. The system may not be provisioned accord Then I realised something was different this time. I shutdown and undefined the Local Engine. The node is now in a degraded state. Is it possible to start the deployment again on a degraded node? I started the old engine again, but I'm not able to reach the login page. Any Idea what to do next?

I have 4.3.3 on engine and hosts in 4.3.3 with plain CentOS, updated from 4.3.2 on 2/5. Since the day after, 3/5, I get the event Check for available updates on host ov200 was completed successfully with message 'found updates for packages ovirt-host'. and also the icon at side of host in web admin gui. But: [root@ov200 ~]# yum update Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager, : vdsmupgrade This system is not registered with an entitlement server.

silent install failing in 4.3.3.5-1 due to question on fqdn of host
by Brian Kircher 07 May '19

Anyone happen to know if I can get the following into an answer file for a silent deployment? It’s asking to confirm or change from the fqdn of the host doing the HE install. Default is fine, but I have to connect in to the screen to answer this before it will continue. Default hostname changed to generic in below log. Forward and reverse are both working via dns.

Re: Best arquitecture for 2 location
by Strahil 07 May '19

07 May '19

You may use gluster with geo-replucation, but that doesn't support gluster updates from remote to local side, so the second location is your DR site and nothing else should be running. Maybe Simone/Sahina can clarify the ovirt part of the setup. Best Regards, Strahil NikolovOn May 6, 2019 18:15, raul.caballero.girol(a)gmail.com wrote: > > Hi everybody, > > I have 2 location separate geographically. I want to deploy an ovirt installation. Evary location has 3 host with a storage system. What is the best arquitecture for this scenario?. My problem is that I don know how to recover the manager if its storage is down. With a backup/recover? How I remove the old manager when I recover the storage? > > Cheers > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/O2TACPYDX3OYK…

replaced ovirt certs, now i'm locked out with unable to find valid certification path
by michael＠wanderingmad.com 07 May '19

07 May '19

I followed the guide here to replace the self-signed certs with 3rd party certs, and now i'm getting this error on signin: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target do i need to have the .p12 in place also? I extracted the .key and .cer from the existing PFX, and copied them to all the places in the article, renaming the .cer to .pem as neded and I always get that error. Yes, I did copy to the java directory and ran the program to update the trust store, and I can list out the trust store and see it listed. Has there been a recent change in how it handles certs? I tried it with the blank password for the certstore, with "changeit" and also changing the password to "123456" and none work.

Problem with restoring engine
by Andreas Elvers 06 May '19

06 May '19

Hello today I tried to migrate the hosted engine from our Default Datacenter (NFS) to our Ceph Datacenter. The deployment worked with the automatic "hosted-engine --deploy --restore-from-file=backup/file_name" command. Perfect. Only thing is: I messed up with the cluster name. The name should be Luise01 but I entered Luise1. Duh... Now I want to bring the engine back to the Default Datacenter. Easy thing. Just repeat the same steps again. 1. Enable global ha maintenenace 2. Stop and disable the engine 3. create the engine backup 4 ... continue with all the steps from chapter 13.1.8 RHEV Docs 4.3 Beta. Everything looked great. The ansible playbook was running, then asking for the storage domain. I entered the NFS path. It got registered, but then the ansible playbook errors out with [ INFO ] TASK [ovirt.hosted_engine_setup : Add VM] [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Cannot attach Virtual Disk. The target Data Center does not contain the Virtual Disk.]". HTTP response code is 409. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Cannot attach Virtual Disk. The target Data Center does not contain the Virtual Disk.]\". HTTP response code is 409."} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook [ INFO ] Stage: Clean up [ INFO ] Cleaning temporary resources I see that there is a bug report on https://bugzilla.redhat.com/show_bug.cgi?id=1649424 Any idea how to get around this error ? Additionally I now have a HostedEngineLocal (shut off) on that node... How do I remove it? engine-cleanup ? Have to get some sleep. best regards.

NonResponsive Host and unknown VMs
by Alexis Grillon 06 May '19

06 May '19

Hello, Context : (probably) After a failed deletion of snapshot during a backup (it had been somes times since i got this problem), one of my host has gone Nonresponsive, and with him, all the VMs who was stored on it or run on it. Instead of removing the problem snapshot (usually it does the trick). I did reboot the host (and without maintenance, it wasn't available) On the Host log, it seems there's nothing wrong, on the Engine log, there's mostly a "ERROR [org.ovirt.engine.core.dal.dbbroker. auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-10) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM xxx command Get Host Capabilities failed: Message timeout which can be caused by communication issues", without further informations. One last thing, it seems gluster is working well but the command "gluster volume status" goes timeout (nothing from log seems wrong) Of course, the host ping from the engine, and the engine ping from the host. You'll find on the bottom of the mail more informations about the setup. Here are a few questions if someone can help : - Should i open a bug on that (looks a lot like https://bugzilla.redhat.com/show_bug.cgi?id=1404082 but i can't do all the test of this bug) ? - Should i be worried about the gluster timeout (the engine is on it) / should i move the gluster point of the unresponsive host on another, and remove the unresponsive host from the pool to fix that ? - i guess that if i fix the unresponsivness of the host, it'll fix the vm (that one is an easy one i hope !) - Once i will have found why the host is unresponsive, and if i can't fix it (have to reinstall it by example), how can i remove the host and the affected vms from the cluster (nearly everything is unavailable on them, maintenance for storage and host are unavailable) ? Any help will be greatly appreciated, thank you. Informations about the setup : ovirt 4.2.8.2 Gluster has been created on system before the installation of ovirt (but is well working this way). Mostly, storage of VMs are made with NFS mount on host, not on a gluster exception made for the engine. The unresponsive host is the arbiter brick of the gluster volumes. I can wipe the unresponsive host, but the cluster is a production cluster, i can't shutdown everything :) ---- Cordialement, Alexis Grillon Pôle Humanités Numériques, Outils, Méthodes et Analyse de Données.
