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

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?

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

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.

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.
