Adding user to internalz with webadmin?
by Juhani Rautiainen 26 Feb '19

Hi! How do you add users to internalz with webadmin? I mean there is add a button in Administration->Users which opens 'Add Users and Groups'-window . Windows has 'Add'- and 'Add and close'- buttons in the bottom. Just can't figure out how they work. Pushing either of those Add-buttons just closes the window. -Juhani

Tracking down high writes in GlusterFS volume
by Jayme 26 Feb '19

26 Feb '19

Running an oVirt 4.3 HCI 3-way replica cluster with SSD backed storage. I've noticed that my SSD writes (smart Total_LBAs_Written) are quite high on one particular drive. Specifically I've noticed one volume is much much higher total bytes written than others (despite using less overall space). My volume is writing over 1TB of data per day (by my manual calculation, and with glusterfs profiling) and wearing my SSDs quickly, how can I best determine which VM or process is at fault here? There are 5 low use VMs using the volume in question. I'm attempting to track iostats on each of the vm's individually but so far I'm not seeing anything obvious that would account for 1TB of writes per day that the gluster volume is reporting.

Add compute nodes offline

Hi, when I add compute nodes, I do not intend to add compute nodes to the engine controller without connecting to the external network: An error has occurred during installation of Host node5.test.com: Failed to execute stage 'Environment customization': Cannot retrieve metalink for repository: Please verify its path and try again. Do I need to manually download some offline packages in this case?

Windows service applications migrated to the ovirt platform

Hi，I now have a physical machine on which I want to migrate Windows applications to the ovirt management platform. May I ask if virt-p2v can be used for migration? Does ovirt itself have a migration tool to use?

Python-SDK4- Issue following links

Hi I am trying to write some code to update the names of existing vnicprofiles in ovirt-4.2. The problem I am having is trying to follow the links to the vnicprofiles.

Unrecognized message received error when ISO domain is put in Maintenance
by Wood Peter 26 Feb '19

26 Feb '19

Hi all, We are running oVirt 4.1.1 on engine and nodes. The ISO storage domain is NFS. Everything has been working great for years. Now I need to move the ISO and Export domains to a different storage server. When I put the ISO domain in maintenance the Master domain and the Export domain start flipping active-non active. The Events tab in the Web UI shows this message scrolling every 30 sec. or so: "Datacenter is being initialized. Please wait for initialization to complete" ... but it never completes. It also starts cycling the SPM assignment from one node to another. As soon as I activate back the ISO domain everything calms down and no more errors are recorded in the logs. In engine.log I see this "Unrecognized message received" error: 2019-02-25 19:45:20,467-08 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] Unable to process messages Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler6) [76363b98] EVENT_ID: IRS_BROKER_COMMAND_FAILURE(10,803), Correlation ID: null, Call Stack: null, Custom E vent ID: -1, Message: VDSM command GetStoragePoolInfoVDS failed: Unrecognized message received 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] ERROR, org.ovirt.engine.core.vdsbroker.irsbroker.GetStoragePoolInfoVDSCommand, exception: VDSGenericExce ption: VDSNetworkException: Unrecognized message received , log id: 1635c439 2019-02-25 19:45:20,481-08 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (DefaultQuartzScheduler6) [76363b98] Exception: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException: VDSGenericException: VDSNetwor kException: Unrecognized message received In vdsm.log on the nodes I see this: 2019-02-25 19:45:29,817-0800 ERROR (upgrade/b5b7a10) [storage.StoragePool] Unhandled exception (utils:371) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 368, in wrapper return f(*a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/concurrent.py", line 180, in run return func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 79, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 232, in _upgradePoolDomain self._finalizePoolUpgradeIfNeeded() File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 77, in wrapper raise SecureError("Secured object is not in safe state") SecureError: Secured object is not in safe state And I believe that after that error it moves the SPM to another host, gets the same error and continues moving it to the next host and so on. I really need to move the ISO and Export domains to a different storage server. Any idea what is causing this or how to fix it? Appreciate any help. Thanks, -- Peter

/boot partition of oVirt node missing after reboot
by andy.law＠hactlsolutions.com 26 Feb '19

26 Feb '19

I've installed oVirt Node 4.2 on one of my servers. Recently I've upgraded the kernel version to 3.10.0-957.5.1.el7.x86_64. After such update, I've rebooted the server to take effect and then the /boot partition cannot be recognized. The server then enters emergency mode and I've tried to run the command blkid but I cannot find the uuid of /boot and /boot/efi.

Stuck completing last step of 4.3 upgrade
by Jayme 25 Feb '19

25 Feb '19

Environment setup: 3 Host HCI GlusterFS setup. Identical hosts, Dell R720s w/ Intel E5-2690 CPUs 1 default data center (4.2 compat) 1 default cluster (4.2 compat) Situation: I recently upgraded my three node HCI cluster from Ovirt 4.2 to 4.3. I did so by first updating the engine to 4.3 then upgrading each ovirt-node host to 4.3 and rebooting. Currently engine and all hosts are running 4.3 and all is working fine. To complete the upgrade I need to update cluster compatibility to 4.3 and then data centre to 4.3. This is where I am stuck. The CPU type on cluster is "Intel SandyBridge IBRS Family". This option is no longer available if I select 4.3 compatibility. Any other option chosen such as SandyBridge IBRS SSBD will not allow me to switch to 4.3 as all hosts must be in maintenance mode (which is not possible w/ self hosted engine). I saw another post about this where someone else followed steps to create a second cluster on 4.3 with new CPU type then move one host to it, start engine on it then perform other steps to eventually get to 4.3 compatibility. I tried to add a 4.3 cluster with gluster service and put one of my hosts in to maintenance mode but could not move it to the new cluster, it gave me an error about the host having gluster service. If I try to import gluster config in cluster add UI it fails in engine log with "SERVER_ALREADY_EXISTS_IN_ANOTHER_CLUSTER" My question is, what is the proper procedure for me to complete upgrading my three node HCI environment to 4.3 cluster compatibility along with changing CPU type? Do I really need to create a second cluster and move host(s) to it? If so how can I move an existing host with running gluster service to a new cluster? Thanks in advance!
