Gluster Questions
by Christian Reiss 15 Nov '19

15 Nov '19

Hey folks, Running a 3 node HCI cluster (in testing stages) I would love to hear your input. All nodes are exactly identical and have a local storage of 8tb in SSDs made out of a RAID6. Gluster was setup to match this (Raid6, cluster of 256k). There is the option of compression & dedup, coming from ZFS this is a memory hog and kind of insane. What are your thoughts on compression & dedup at this time? The effective size of the compressed drive is suggested 10-fold of the original sizes. Seems a big crazy high; any suggestions here? Thanks for your input! -Chris. -- Christian Reiss - email(a)christian-reiss.de /"\ ASCII Ribbon support(a)alpha-labs.net \ / Campaign X against HTML WEB alpha-labs.net / \ in eMails GPG Retrieval https://gpg.christian-reiss.de GPG ID ABCD43C5, 0x44E29126ABCD43C5 GPG fingerprint = 9549 F537 2596 86BA 733C A4ED 44E2 9126 ABCD 43C5 "It's better to reign in hell than to serve in heaven.", John Milton, Paradise lost.

External VM vdsbroker parsing error
by Marcus van Dam 14 Nov '19

14 Nov '19

Hi, I am running a two node oVirt cluster, based on the "High-Availability oVirt-Cluster with iSCSI-Storage" document published by Linbit. Although a older document, I am happy with the setup. With this setup, I notice a flood of failed VM imports in the engine logs. This setup is based on a separate Qemu VM running the oVirt-Engine. Which seems to be the origin of the error (posted below). Is there anything I can do to either ignore this instance and not fill the logs, or fix the import error? Thanks! - Marcus ---- %< ---- SNIP ---- %< ----- %< ---- SNIP ---- %< ----- 2019-11-14 14:50:27,155+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.FullListAdapter] (EE-ManagedThreadFactory-engineScheduled-Thread-38) [2e46652f] Failed during parsing configuration of VM 133789fc-b329-40b8-bac3-e3ff8c37b1f9 (<domain type='kvm' id='2'> <name>oVirtm</name> <uuid>133789fc-b329-40b8-bac3-e3ff8c37b1f9</uuid> <memory unit='KiB'>4194304</memory> <currentMemory unit='KiB'>4194304</currentMemory> <vcpu placement='static'>2</vcpu> <resource> <partition>/machine</partition> </resource> <os> <type arch='x86_64' machine='pc-i440fx-rhel7.6.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'> <timer name='kvmclock' present='yes'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <pm> <suspend-to-mem enabled='no'/> <suspend-to-disk enabled='no'/> </pm> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/drbd/by-res/kvm/0'/> <backingStore/> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/etc/ovirtm/seed.iso'/> <backingStore/> <target dev='hda' bus='ide'/> <readonly/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <controller type='usb' index='0' model='none'> <alias name='usb'/> </controller> <controller type='pci' index='0' model='pci-root'> <alias name='pci.0'/> </controller> <controller type='ide' index='0'> <alias name='ide'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <alias name='virtio-serial0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> <interface type='bridge'> <mac address='52:54:00:75:3c:7d'/> <source bridge='ovirtmgmt'/> <target dev='vnet1'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/4'/> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/4'> <source path='/dev/pts/4'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-2-oVirtm/org.qemu.guest_agent.0'/> <target type='virtio' name='org.qemu.guest_agent.0' state='connected'/> <alias name='channel0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <input type='mouse' bus='ps2'> <alias name='input0'/> </input> <input type='keyboard' bus='ps2'> <alias name='input1'/> </input> <video> <model type='vga' vram='16384' heads='1' primary='yes'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='none'/> <rng model='virtio'> <backend model='random'>/dev/urandom</backend> <alias name='rng0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </rng> </devices> <seclabel type='dynamic' model='selinux' relabel='yes'> <label>system_u:system_r:svirt_t:s0:c624,c838</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c624,c838</imagelabel> </seclabel> <seclabel type='dynamic' model='dac' relabel='yes'> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> </domain> ), error is: {}: java.lang.NullPointerException 2019-11-14 14:50:27,155+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.FullListAdapter] (EE-ManagedThreadFactory-engineScheduled-Thread-38) [2e46652f] Exception:: java.lang.NullPointerException

Do I need to use self hosted engine with a GlusterFs three node setup
by donagh.moran＠oracle.com 14 Nov '19

14 Nov '19

Every piece of documentation I read regarding the setup of Gluster seems to suggest using at least one of the the nodes to host the engine. Is this a requirement of can I use an engine that is deployed on a VM on another server in the same network? Any info would be much appreciated.

Gluster Network Issues....
by rob.downer＠orbitalsystems.co.uk 14 Nov '19

14 Nov '19

I have set up 3 SuperMicro's with Ovirt Node and all pretty sweet. FQDN set up for LAN and also after setup I have enabled a second NIC with FQDN for a Gluster network. The issue is the second ports seem to be unavailable for network access by ping or login.... if you login on root the system says that the ports are available for login on the bash shell after login and node check comes back fine. I have IPMI set up on the systems as well for access. am I missing something ? I realise Gluster should be on a seperate LAN and will put it on a 10BGe network but I'm just testing. I have the lastest stable build. Any help would be appreciated.

Hosted-Engine wizard disappeared after cockpit idle session timeout
by wodel youchi 14 Nov '19

14 Nov '19

Hi, I got this behavior once and I didn't tested again. I started the hosted-engine deployment using cockpit webui, the process went smoothly, the LocalHosttedEngine VM was created, at that time I left the console for sometime. When I get back the cockpit console was closed due to idle session timeout, I reconnect, and the hosted-engine wizard had disappeared and I didn't find a way to get it back, the only choice was to start the process again even if the console was showing that the host was registered with a hosted engine Manager, so I couldn't continue the deployment (the storage phase). I had to stop the LocalHosttedEngine VM, delete it's temporary disk, then restart the deployment again and this time I stick with cockpit webui to get it done. Regards.

engine manager VM not launching
by bepassionatenow＠gmail.com 14 Nov '19

14 Nov '19

Good evening/morning, I can't launch the Engine Manager after the initial install through Cockpit. It initially started fine but I could never login. Cockpit showed that the VM was not set to auto-restart. I don't see how to change that and the button to "run" won't work. Spinning box in the top right corner is causing issues (won't register properly). Any help would be greatly appreciated. Thanks! Daniel

Windows Server 2019 crash dxgkrnl.sys
by gregor 13 Nov '19

13 Nov '19

Hello, during the Installation of Windows Server 2019 after the first reboot the VM crashed and inside the ntbtlog.txt I found that dxgkrnl.sys can not be loaded. Environment: oVirt 4.3.6.7-1.el7 CPU: Intel-Westmere Memory: 4096MB Operation System VM config: Windows 2019 x64 HDD: VirtIO-SCSI VirtIO driver: virtio-win-0.1.171_servers_amd64.vfd Does anybody has an hint how to solve this problem and use Windows Server 2019? Besides: It's possible to install and use Windows Server 2019 in VirtualBox 6.*. We have to install it in the meantime there to have a alternative solution because it took now about two days to find a solution. We tried different settings for VGA and drivers IDE ... and many more. best regards gregor

oVirt change IP's & add new ISO share
by Jonathan Mathews 13 Nov '19

13 Nov '19

Good Day I have to change the IP addresses of the oVirt Engine, hosts and storage to a new IP range. Please, can you advise the best way to do this and if there is anything I would need to change in the database? I have also run into an issue where someone has removed the ISO share/data on the storage, so I am unable to remove, activate, detach or even add a new ISO share. Please, can you advise the best wat to resolve this? Please see the below engine logs: 2019-10-30 11:39:13,918 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.DetachStorageDomainVDSCommand] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] Failed in 'DetachStorageDomainVDS' method 2019-10-30 11:39:13,942 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VDSM command failed: Storage domain does not exist: (u'42b7d819-ce3a-4a18-a683-f4817c4bdb06',) 2019-10-30 11:39:13,943 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] IrsBroker::Failed::DetachStorageDomainVDS: IRSGenericException: IRSErrorException: Failed to DetachStorageDomainVDS, error = Storage domain does not exist: (u'42b7d819-ce3a-4a18-a683-f4817c4bdb06',), code = 358 2019-10-30 11:39:13,951 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.DetachStorageDomainVDSCommand] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] FINISH, DetachStorageDomainVDSCommand, log id: 5547e2df 2019-10-30 11:39:13,951 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.SPMGetAllTasksInfoVDSCommand] (org.ovirt.thread.pool-8-thread-38) [58f6cfb8] -- executeIrsBrokerCommand: Attempting on storage pool '5849b030-626e-47cb-ad90-3ce782d831b3' 2019-10-30 11:39:13,951 ERROR [org.ovirt.engine.core.bll.storage.DetachStorageDomainFromPoolCommand] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] Command 'org.ovirt.engine.core.bll.storage.DetachStorageDomainFromPoolCommand' failed: EngineException: org.ovirt.engine.core.vdsbroker.irsbroker.IRSErrorException: IRSGenericException: IRSErrorException: Failed to DetachStorageDomainVDS, error = Storage domain does not exist: (u'42b7d819-ce3a-4a18-a683-f4817c4bdb06',), code = 358 (Failed with error StorageDomainDoesNotExist and code 358) 2019-10-30 11:39:13,952 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.HSMGetAllTasksInfoVDSCommand] (org.ovirt.thread.pool-8-thread-38) [58f6cfb8] START, HSMGetAllTasksInfoVDSCommand(HostName = host01, VdsIdVDSCommandParametersBase:{runAsync='true', hostId='291a3a19-7467-4783-a6f7-2b2dd0de9ad3'}), log id: 6cc238fb 2019-10-30 11:39:13,952 INFO [org.ovirt.engine.core.bll.storage.DetachStorageDomainFromPoolCommand] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] Command [id=cec030b7-4a62-43a2-9ae8-de56a5d71ef8]: Compensating CHANGED_STATUS_ONLY of org.ovirt.engine.core.common.businessentities.StoragePoolIsoMap; snapshot: EntityStatusSnapshot:{id='StoragePoolIsoMapId:{storagePoolId='5849b030-626e-47cb-ad90-3ce782d831b3', storageId='42b7d819-ce3a-4a18-a683-f4817c4bdb06'}', status='Inactive'}. 2019-10-30 11:39:13,975 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-8-thread-27) [58f6cfb8] Correlation ID: 28ac658, Job ID: b31e0f44-2d82-47bf-90d9-f69e399d994f, Call Stack: null, Custom Event ID: -1, Message: Failed to detach Storage Domain iso to Data Center Default.
