ovirt-engine-webadmin-portal-debuginfo

Hello, I've run into a situation where I'm getting an uncaught exception error and it seems like the log entries are obfuscated and one needs to install the ovirt-engine-weba-portal-debuginfo rpm to decipher whats really going on. I've installed this package and restarted the ovirt-engine but I'm still not getting useful info in the ui.log. Any ideas what how I can resolve this? # rpm -qa|grep ovirt.*debuginfo ovirt-engine-userportal-debuginfo-4.0.5.5-1.el7.centos.noarch ovirt-engine-webadmin-portal-debuginfo-4.0.5.5-1.el7.centos.noarch This is an example of the log entry when attempting to create a vm using a template that contains a disk. 2017-02-06 14:42:15,538 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-67) [] Permutation name: 587E534EAE351BE2F229E0B865EFB2D3 2017-02-06 14:42:15,539 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-67) [] Uncaught exception: com.google.gwt.core.client.JavaScriptException: (TypeError) __gwt$exception: <skipped>: Cannot read property 'f' of undefined at org.ovirt.engine.ui.uicommonweb.models.storage.DisksAllocationModel.$updateImageToDestinationDomainMap(DisksAllocationModel.java:307) at org.ovirt.engine.ui.uicommonweb.models.storage.DisksAllocationModel.$getImageToDestinationDomainMap(DisksAllocationModel.java:133) at org.ovirt.engine.ui.uicommonweb.models.userportal.UserPortalListModel.$postVmNameUniqueCheck(UserPortalListModel.java:975) at org.ovirt.engine.ui.uicommonweb.models.userportal.UserPortalListModel$10.onSuccess(UserPortalListModel.java:921) at org.ovirt.engine.ui.frontend.Frontend$2.$onSuccess(Frontend.java:238) [frontend.jar:] at org.ovirt.engine.ui.frontend.Frontend$2.onSuccess(Frontend.java:238) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.OperationProcessor$2.$onSuccess(OperationProcessor.java:139) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.OperationProcessor$2.onSuccess(OperationProcessor.java:139) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$3$1.$onSuccess(GWTRPCCommunicationProvider.java:160) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$3$1.onSuccess(GWTRPCCommunicationProvider.java:160) [frontend.jar:] at com.google.gwt.rpc.client.impl.RpcCallbackAdapter.onResponseReceived(RpcCallbackAdapter.java:72) [gwt-servlet.jar:] at com.google.gwt.http.client.Request.$fireOnResponseReceived(Request.java:237) [gwt-servlet.jar:] at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:409) [gwt-servlet.jar:] at Unknown.eval(userportal-0.js@65) at com.google.gwt.core.client.impl.Impl.apply(Impl.java:296) [gwt-servlet.jar:] at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:335) [gwt-servlet.jar:] at Unknown.eval(userportal-0.js@54) Is this as clear as the ui.log will get? -- Best regards, Edward Clay Systems Administrator UK2 Group - US Operations Phone: 1-800-222-2165 FAX: 435-755-3449 E-mail: edward.clay(a)uk2group.com Believe in Better Hosting http://www.westhost.com

06 Feb '17

Hi everyone, In a couple of minutes I will reboot the server hosting all of our mailing lists (including this one) to install software updates. It should come up quickly, but if you have any problems sending to oVirt lists please try again after a few minutes. I will announce you as soon as the reboot is complete. Regards, Evgheni Dereveanchin

Restoring Hosted-Engine from a stale backup
by Doug Ingham 06 Feb '17

06 Feb '17

Hi all, One of our engines has had a DB failure* & it seems there was an unnoticed problem in its backup routine, meaning the last backup I've got is a couple of weeks old. Luckily, VDSM has kept the underlying VMs running without any interruptions, so my objective is to get the HE back online & get the hosts & VMs back under its control with minimal downtime. So, my questions are the following... 1. What problems can I expect to have with VMs added/modified since the last backup? 2. As it's only the DB that's been affected, can I skip redeploying the Engine & jump straight to restoring the DB & rerunning engine-setup? 3. The original docs I read didn't mention that it's best to leave a host in maintenance mode before running the engine backup, so my plan is to install a new temporary host on a separate server, re-add the old hosts & then once everything's back up, remove the temporary host. Are there any faults in this plan? 4. When it comes to deleting the old HE VM, the docs point to a paywalled guide on redhat.com...? CentOS 7 oVirt 4.0.4 Gluster 3.8 * Apparently a write somehow cleared fsync, despite not actually having been written to disk?! No idea how that happened... Many thanks, -- Doug

Can you please describe it in detail? How many hosts do you have? What's the state of each in the engine? Do you have VMs that are ok? And if so, is it important to not stop them? In any case, if you have hosts that do not have VMs on them, and in whatever state, it's probably simplest to move them to maintenance, remove from the engine, reinstall the OS, then try to add them. If you try to add a host and it fails, please check/attach engine.log and host-deploy log. If you fail to activate a host, please check/attach engine.log.

jumbo frames inside vm best practices?
by Gianluca Cecchi 06 Feb '17

06 Feb '17

Hello, I'm testing an Oracle RAC with 2 Oracle Linux VMs inside a 4.0.6 environment. They run on two different hosts I would like to configure RAC intracluster communication with jumbo frames. At VM level network adapter is eth1 (mapped to a vlan 95 at oVirt hosts side) At oVirt side I configured a vm enabled vlan with mtu=9000 I verified that at hosts side I have vlan95: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 ether 00:1c:c4:ab:be:ba txqueuelen 1000 (Ethernet) RX packets 61706 bytes 3631426 (3.4 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3 bytes 258 (258.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 And able to do a ping -M do -s 8972 ip from each host to the other one In VMs I configure the same MTU=9000 in ifcfg-eth1 But actually inside VMs it works erratically: the same ping test is ok between the VMs but Oracle checks sometimes work and sometimes give error on communication. At initial cluster config, the second node fails to start the cluster. I tried 5-6 times and also tried then to set mtu=8000 inside the VMs, supposing some sort of inner overhead to consider (such as 2 times 28 bytes) but nothing. As soon as I set MTU=1500 at VM side, the cluster is able to form without any problem. I can survive without jumbo frames in this particular case, because this is only a test, but the question remains about eventual best practices to put in place if I want to use jumbo frames. One thing I see is that at VM side I see many drops when interface mtu was 9000, such as eth1 Link encap:Ethernet HWaddr 00:1A:4A:17:01:57 inet addr:192.168.10.32 Bcast:192.168.10.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:93046 errors:0 dropped:54964 overruns:0 frame:0 TX packets:26258 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:25726242 (24.5 MiB) TX bytes:33573207 (32.0 MiB) at host side I see drops at bond0 level only: [root@ovmsrv05 ~]# brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no vlan100 8000.001cc446ef73 no bond1.100 vlan65 8000.001cc446ef73 no bond1.65 vnet0 vnet1 vlan95 8000.001cc4abbeba no bond0.95 vnet2 bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST> mtu 9000 ether 00:1c:c4:ab:be:ba txqueuelen 1000 (Ethernet) RX packets 2855175 bytes 3126868334 (2.9 GiB) RX errors 0 dropped 11686 overruns 0 frame 0 TX packets 1012849 bytes 478702140 (456.5 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 bond0.95: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 ether 00:1c:c4:ab:be:ba txqueuelen 1000 (Ethernet) RX packets 100272 bytes 27125992 (25.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 42355 bytes 40833904 (38.9 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 vlan95: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 ether 00:1c:c4:ab:be:ba txqueuelen 1000 (Ethernet) RX packets 62576 bytes 3719175 (3.5 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3 bytes 258 (258.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 vnet2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 inet6 fe80::fc1a:4aff:fe17:157 prefixlen 64 scopeid 0x20<link> ether fe:1a:4a:17:01:57 txqueuelen 1000 (Ethernet) RX packets 21014 bytes 24139492 (23.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 85777 bytes 21089777 (20.1 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@ovmsrv05 ~]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: enp3s0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: enp3s0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:1c:c4:ab:be:ba Slave queue ID: 0 Slave Interface: enp5s0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:1c:c4:ab:be:bc Slave queue ID: 0 Any hint?
