VM paused then killed with "device vda reported I/O error"
by fsoyer 31 Oct '18

31 Oct '18

Hi, related (or maybe not) with my problem "VMs unexpectidly restarted", I have one VM (only one) which was paused then killed this morning (1:01AM). This is the second time (first time about 15 days ago), only this one (it is on a domain with 5 others VMs, and it is not the most used of them. And it was at night, without any particular treatment at this time). The others VMs on the same storage were not impacted at all. And it is not on the same storage domain as the other VM of "VMs unexpectidly restarted"... At the same time, gluster seems to have seen absolutly nothing. Is there really a storage issue ?? Here are some revelant logs /var/log/messages of the node vdsm.log engine.log glusterd.log data01-brick.log For recall, this is a 3 nodes 4.2.3 cluster, on Gluster 3.12.13 (2+arbiter). Any idea where or what I must search for ? Thanks -- Cordialement, Frank

SR-IOV / No free VF (pci=assign-busses issue ?)
by jeanbaptiste＠nfrance.com 31 Oct '18

31 Oct '18

Hello, I'm facing an issue since days regarding SR-IOV. On a specific configuration, I'm unable to start VM with a VF. Tyan S5510 + Intel E3 1220 (vt-x and vt-d enabled). I've enable 63 VF (intel X520-DA2). Engine interface show me : Enabled virtual function: 63 Free Virtual function: 63 I've create a Network + vNIC profile (Passthrough enabled) I have the same issue if I force mapping "Allowed Networks / All networks / Specific networks" or not (on host setup network) When I try to start VM Engine error message is: Failed to run VM test due to a failed validation: [Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host sriov-hp1.admin-lan.nfrance.com did not satisfy internal filter Network because there are no free virtual functions which are suitable for virtual nic(s) nic1. A virtual function is considered as suitable if the VF's configuration of its physical function contains the virtual nic's network/network label.] (User: admin@internal-authz). Problem seem not be related to host. VF are visible into ip l on my host. Unfortunately, I have no representative error log on side host or engine log (expect error above on engine log) For information, kernel parameters on host are: intel_iommu=on pci=assign-busses. pci=assign-busses is mandatory on this motherboard otherwise VF cannot be created. Do you have idea ?

oVirt: 4.2.6.2-1 I'm Moving hosted engine from one storage domain to another by backing up and restoring the engine. New VM provisioned in new storage domain, I get as far as trying to restore the backup: but am getting this DbJustRestored Error: engine-backup --mode=restore --file=engine.backup --log=engine-restore.log --provision-db --provision-dwh-db --restore-permissions Preparing to restore: - Unpacking file 'engine.backup' Restoring: - Files Provisioning PostgreSQL users/databases: - user 'engine', database 'engine' - user 'ovirt_engine_history', database 'ovirt_engine_history' Restoring: - Engine database 'engine' - Cleaning up temporary tables in engine database 'engine' FATAL: Failed checking DbJustRestored restore log attached, any suggestions ?

Re: Storage domain mount error: Lustre file system(Posix compliant FS)

Um... Does the gluster included in version 4.2.7 improve small file I/O performance? If that 's the case, I will test you as you say. Finally, I want to ask one more time. How can I use lustre? 보내는사람 : Yaniv Kaul <ykaul(a)redhat.com> 받는사람 : '김형근'<okok102928(a)fusiondata.co.kr> 참조 : Ovirt Users <users(a)ovirt.org> 보낸 날짜 : 2018-10-29 16:57:57 제목 : Re: [ovirt-users] Storage domain mount error: Lustre file system(Posix compliant FS) On Thu, Oct 25, 2018 at 7:25 AM <okok102928(a)fusiondata.co.kr> wrote: Hi.

I am testing Lustre File System in Ovirt or RH(E)V environment. (The reason is simple: glusterfs and nfs have limit of performance, SAN Storage and excellent Software Defined Storage are quite expensive.) Please re-test Gluster with latest 4.2.7, where we have improved performance nicely specifically for Gluster based storage. Testing for file system performance was successful.

GetGlusterLocalLogicalVolumeListVDSCommand execution failed: null
by Marco Lorenzo Crociani 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__ADD,ACTION_TYPE_FAILED_DISCARD_AFTER_DELETE_NOT_SUPPORTED_BY_UNDERLYING_STORAGE,$storageDomainName VicinityStorageDomain 2018-10-30 06:26:32,713-04 INFO [org.ovirt.engine.core.bll.storage.domain.AttachStorageDomainToPoolCommand] (default task-13) [772f360b-453c-407a-90ac-b28a3915e377] No permission found for user '0ad3bf0c-d5e1-11e8-afa0-005056af2f08' or one of the groups he is member of, when running action 'AttachStorageDomainToPool', Required permissions are: Action type: 'ADMIN' Action group: 'MANIPULATE_STORAGE_DOMAIN' Object type: 'Storage' Object ID: 'null'. 2018-10-30 06:26:32,713-04 WARN [org.ovirt.engine.core.bll.storage.domain.AttachStorageDomainToPoolCommand] (default task-13) [772f360b-453c-407a-90ac-b28a3915e377] Validation of action 'AttachStorageDomainToPool' 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.
