GetGlusterLocalLogicalVolumeListVDSCommand execution failed: null
by Marco Lorenzo Crociani 30 Oct '18

30 Oct '18

Hi, I'm updating ovirt to 4.2.6.4-1.el7 Engine is updated Compute nodes are updated Storage nodes are not yet updated because ovirt 4.2.6.4-1.el7 depends on gluster 3.12 while now I have gluster 3.10. Compatibility Versions: Compute datacenter 4.2 Storage 4.1 (because I don't have yet updated the storage cluster) so Data Centers is still 4.1 I was about to upgrade the storage nodes when I noticed that /var/log/ovirt-engine/engine.log is flooded with errors like: 2018-10-25 19:36:17,164+02 ERROR [org.ovirt.engine.core.vdsbroker.gluster.GetGlusterLocalLogicalVolumeListVDSCommand] (DefaultQuartzScheduler2) [55e89794] Command 'GetGlusterLocalLogicalVolumeListVDSCommand(HostName = s23, VdsIdVDSCommandParametersBase:{hostId='84a33357-1d04-44db-b0e3-4638ebc39d6c'})' execution failed: null 6 errors (one for each storage server) every 6 seconds. How could I fix them? Can I continue to upgrade the storage nodes? Best regards, -- Marco Crociani

User Authorization error when adding iSCSI storage
by Tryfon Farmakakis 30 Oct '18

30 Oct '18

Hello. I am using oVirt 4.2.6.4. I have added successfully one Centos 7.5 host. I am trying to create a new Storage Domain to add a local storage device on the host which has an iSCSI target configured on top. Everything seems to proceed fine, iSCSI target is discovered by oVirt and LUN is added and then when I click the OK button the operation fails and shows a user authentication error message which doesn't make any sense since I am logged-in in oVirt as an administrator. Here are the relevant lines from the ovirt engine log file. Any help appreciated: 2018-10-30 06:26:32,492-04 WARN [org.ovirt.engine.core.bll.storage.domain.AddSANStorageDomainCommand] (default task-13) [da237443-21e0-4777-a0d4-3c6ecf6c63bd] Validation of action 'AddSANStorageDomain' failed for user admin@internal-authz.

Reasons: VAR__TYPE__STORAGE__DOMAIN,VAR__ACTION__ATTACH,USER_NOT_AUTHORIZED_TO_PERFORM_ACTION A few extra minor issues that manifest after clicking OK is that I get a warning that the underlying device does not support discard after delete, even though I had that unchecked in the previous dialogue window and then I get a warning that the LUN exists already (doesn't make sense since the new Storage Domain was never created). Moreover the iSCSI initiator that oVirt created on my host is still there and I have to tear it down manually.

Ovirt - Bonded NICs - using as tagged and untagged at the same time
by pslawrence＠comcast.net 30 Oct '18

30 Oct '18

Hello, I have searched and have not found an answer with respects to Ovirt and VLAN tagging. I'm hoping someone will be able to assist. I am using two 10GB interfaces bonded 802.3ad for our second interface. I have created several interfaces that are tagged with specific VLANs and 1 interface called 20GBBond that is untagged. The issue we are experiencing is when I assign a vlan to an interface I can no longer assign it to the 20GBBond on a VM. For example, ETH1 is tagged with VLAN70 is tagged and assigned to VM1. 20GBBond untagged interface is assigned to VM2 and within the VM i create the tagged sub interface eth1.70. Once I create the single ETH1 VLAN70 interface on VM1, I can no longer use the sub interface eth1.70 created on VM2. Is there a way to get around this if it is a limitation.

Here it is at the time of the restart : https://gist.github.com/fsoyer/8d6952e85623a12f09317652aa4babd7 (hope that you can display this gists) First question : there is all the days those message "delta_renew long write time". What does this mean ? Even if I suspect some storage problem, I don't see latency on it (configuration described bellow). Second question : what append that force some VMs (not all, and not and the sams host !) to restart ? Where and what must I search for ? Thanks Configuration 2 DELL R620 as ovirt hosts (4.2.8-2) with hosted-engine, also members of a gluster 3.12.13-1 cluster with an arbiter (1 DELL R310, non-ovirt). The DATAs and ENGINE storages are on gluster volumes. Around 11am, I do not see any specific messages in glusterd.log or glfsheal-*.log. Gluster is on a separate network (2*1G bond mode 4=aggegation) than ovirmgmt (2*1G bond mode 1=failover). -- Regards, Frank

Hi, I have recently installed ovirt version 4.2.6 in my infrastructure with 3 hosts and Fiber Channel SAN. I have also integrated the engine with Active Directory using ovirt-engine-extensions-aaa-ldap using the recommended procedure and the integration went through without any error. However, when I try to login to Administration / User Portal I receive error "server_error: Cannot resolve principle 'user(a)example.com' Can someone help to get over this issue? -- Thanks & regards, Anantha Raghava Do not print this e-mail unless required.

ETL service and winter hour
by fsoyer 29 Oct '18

29 Oct '18

Hi all, Maybe it has already been posted, but I think I've discoverd a little bug. This night I had this messages : 28 oct. 2018 03:00:00 ETL service aggregation to hourly tables has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:40:27 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:33:42 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:27:42 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:22:27 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:16:37 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:11:06 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:05:06 ETL service sampling has encountered an error. Please consult the service log for more details. 28 oct. 2018 02:00:06 ETL service sampling has encountered an error. Please consult the service log for more details 28 oct. 2018 02:00:00 ETL service aggregation to hourly tables has encountered an error. Please consult the service log for more details.and, coincidence, here in France we have change to winter hour at... 2AM :) So regarding this post: https://access.redhat.com/solutions/3338001 speaking about a time problem, I've supposed that this is related ! No ? access.redhat says that the cause was not yet determined, but maybe it can be interesting to propose this cause ? But the bug is actually closed. Question : does this repair all alone (as there is no more messages after 3AM) or may I applied the solution with postgres updates (I must say that I'm not very enthousiast for that...) ? Regards, -- Frank

Involuntary emergency upgrade from 4.1 to 4.2
by djohnson＠maxistechnology.com 28 Oct '18

28 Oct '18

I'm looking for a hand in recovering my ovirt cluster from a hardware failure. The hard drive on my cluster controller failed, and I would like to recover from backup. The problem is, the cluster was 4.1, which is less than a year old, but was nevertheless removed from the active repositories back in May. 4.2 will not recover from 4.1 backups. The storage domains are all intact (I think), and the hosts are still running (unmanaged). I've tried to manually restore the engine from backups, but either the upgrade is reinitializing or I am missing something. I am unable to see the existing storage domains from the newly built controller, and am at a loss. Any ideas?
