Migrating from RHV to ovirt
by Andrés Jiménez 06 May '19

06 May '19

Hi, all I do have a 5 hosts cluster with over 300 VMs in production with Red Hat Virtualization version 4.2.8 and I am willing to switch to a pure CentOS + oVirt 4.2 setup. Management is based in a RHVM hosted-engine in a dedicated iSCSI DataStore and our hosts are a mix of RHVH nodes (3) and CentOS with oVirt 4.2 repositories (2). I was wondering if I can just set up a new hosted-engine in a CentOS host and recover a backup of our current ovirt- engine (rhvm). Would that work straight away without affecting my running VMs?

Please Help, Ovirt Node Hosted Engine Deployment Problems 4.3.2
by Todd Barton 06 May '19

06 May '19

I've having to rebuild an environment that started back in the early 3.x days. A lot has changed and I'm attempting to use the Ovirt Node based setup to build a new environment, but I can't get through the hosted engine deployment process via the cockpit (I've done command line as well). I've tried static DHCP address and static IPs as well as confirmed I have resolvable host-names. This is a test environment so I can work through any issues in deployment. When the cockpit is displaying the waiting for host to come up task, the cockpit gets disconnected. It appears to a happen when the bridge network is setup. At that point, the deployment is messed up and I can't return to the cockpit. I've tried this with one or two nic/interfaces and tried every permutation of static and dynamic ip addresses. I've spent a week trying different setups and I've got to be doing something stupid. Attached is a screen capture of the resulting IP info after my latest try failing. I used two nics, one for the gluster and bridge network and the other for the ovirt cockpit access. I can't access cockpit on either ip address after the failure. I've attempted this setup as both a single host hyper-converged setup and a three host hyper-converged environment...same issue in both. Can someone please help me or give me some thoughts on what is wrong? Thanks! Todd Barton

Stale hosted engine node information harmful ?
by Andreas Elvers 02 May '19

02 May '19

I have 5 nodes (node01 to node05). Originally all those nodes were part of our default datacenter/cluster with a NFS storage domain for vmdisk, engine and iso-images. All five nodes were engine HA nodes. Later node01, node02 and node03 were re-installed to have engine HA removed. Then those nodes were removed from the default cluster. Eventually node01,02 and 03 were completely re-installed to host our new Ceph/Gluster based datecenter. The engine is still running on the old default Datacenter. Now I wish to move it over to our ceph/gluster datacenter. when I look at the current output of "hosted-engine --vm-status" I see: --== Host node01.infra.solutions.work (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node01.infra.solutions.work Host ID : 1 Engine status : unknown stale-data Score : 0 stopped : True Local maintenance : False crc32 : e437bff4 local_conf_timestamp : 155627 Host timestamp : 155877 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=155877 (Fri Aug 3 13:09:19 2018) host-id=1 score=0 vm_conf_refresh_time=155627 (Fri Aug 3 13:05:08 2018) conf_on_shared_storage=True maintenance=False state=AgentStopped stopped=True --== Host node02.infra.solutions.work (id: 2) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node02.infra.solutions.work Host ID : 2 Engine status : unknown stale-data Score : 0 stopped : True Local maintenance : False crc32 : 11185b04 local_conf_timestamp : 154757 Host timestamp : 154856 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=154856 (Fri Aug 3 13:22:19 2018) host-id=2 score=0 vm_conf_refresh_time=154757 (Fri Aug 3 13:20:40 2018) conf_on_shared_storage=True maintenance=False state=AgentStopped stopped=True --== Host node03.infra.solutions.work (id: 3) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : node03.infra.solutions.work Host ID : 3 Engine status : unknown stale-data Score : 0 stopped : False Local maintenance : True crc32 : 9595bed9 local_conf_timestamp : 14363 Host timestamp : 14362 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=14362 (Thu Aug 2 18:03:25 2018) host-id=3 score=0 vm_conf_refresh_time=14363 (Thu Aug 2 18:03:25 2018) conf_on_shared_storage=True maintenance=True state=LocalMaintenance stopped=False --== Host node04.infra.solutions.work (id: 4) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : node04.infra.solutions.work Host ID : 4 Engine status : {"health": "good", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : 245854b1 local_conf_timestamp : 317498 Host timestamp : 317498 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=317498 (Thu May 2 09:44:47 2019) host-id=4 score=3400 vm_conf_refresh_time=317498 (Thu May 2 09:44:47 2019) conf_on_shared_storage=True maintenance=False state=EngineUp stopped=False --== Host node05.infra.solutions.work (id: 5) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : node05.infra.solutions.work Host ID : 5 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 0711afa0 local_conf_timestamp : 318044 Host timestamp : 318044 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=318044 (Thu May 2 09:44:45 2019) host-id=5 score=3400 vm_conf_refresh_time=318044 (Thu May 2 09:44:45 2019) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False The old node01, node02 and node03 are still present. The new incarnations of node01, node02 and node03 will be the destination the the deployment of the new home of our engine to which I wish to restore the backup to. But I'm not sure, if (and how) the old date should be removed first.

oVirt 4.3.3 - servers cannot be reached
by Wood Peter 02 May '19

02 May '19

Hi, I setup AD authentication and from command line all looks good. Unfortunately, on the Web UI users sometimes login successfully but most of the times the login screen just hangs and after 2-3 min. it displays "Unable to log in because servers cannot be reached. Try again later." In engine.log I see this: 2019-05-02 11:12:11,581-07 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-72) [] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User peter(a)ad.mycompany.com connecting from '10.12.29.48' failed to log in : 'Unable to log in because servers cannot be reached. Try again later.'. 2019-05-02 11:12:11,583-07 ERROR [org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default task-68) [] Cannot authenticate user 'peter(a)ad.mycompany.com' connecting from '10.12.29.48': Unable to log in because servers cannot be reached. Try again later. Even when my login attempt on the Web UI is hanging I can still successfully run the login test from shell: ovirt-engine-extensions-tool aaa login-user --profile=ad.mycompany.com --user-name=peter The above command never fails. That makes me wonder why am I getting the "servers cannot be reached" error? I assume the AD servers cannot be reached but from the command line it works perfect every time. Any idea what could be the problem or where to look for the error. Thank you, -- Peter

Prevent Gluster Volume being monitored by oVirt
by smirta＠gmx.net 02 May '19

02 May '19

Dear all We are running a oVirt GlusterFS hyperconverged setup with arbiter version 4.2.6.4-1.el7 here. It looks like we are affected by this bug https://bugzilla.redhat.com/show_bug.cgi?id=1614430 with one or more gluster volumes that are not storage domains of oVirt. Is there a way to exclude them from monitoring (vdsm-gluster) or to prevent being added to the engine's database? Thanks Simon

Re: Stale hosted engine node information harmful ?

In a Red Hat Solution , it is recommended to restart ovirt-ha-agent & ovirt-ha-broker. I usually set the global maintenance and wait 20s-30s . Then I just stop on all nodes ovirt-ha-agent.service & ovirt-ha-broker.service . Once everywhere is stopped, start the 2 services on all nodes and wait 4-5min. Last verify the status from each host, before removing global maintenance.

Re: All hosts non-operational after upgrading from 4.2 to 4.3

Are you able to access your iSCSI via the /rhev/data-center/mnt... mount point ? Best Regards, Strahil NikolovOn Apr 5, 2019 19:04, John Florian <jflorian(a)doubledog.org> wrote: > > I am in a severe pinch here. A while back I upgraded from 4.2.8 to 4.3.3 and only had one step remaining and that was to set the cluster compat level to 4.3 (from 4.2). When I tried this it gave the usual warning that each VM would have to be rebooted to complete, but then I got my first unusual piece when it then told me next that this could not be completed until each host was in maintenance mode. Quirky I thought, but I stopped all VMs and put both hosts into maintenance mode. I then set the cluster to 4.3. Things didn't want to become active again and I eventually noticed that I was being told the DC needed to be 4.3 as well. Don't remember that from before, but oh well that was easy. > > However, the DC and SD remains down. The hosts are non-op. I've powered everything off and started fresh but still wind up in the same state. Hosts will look like their active for a bit (green triangle) but then go non-op after about a minute. It appears that my iSCSI sessions are active/logged in.
