Issues with resizing Gluster Volumes with sharding and lookup-optimize enabled
by Strahil Nikolov 08 Nov '21

08 Nov '21

Hello All, I recently found a RH solution regards issues with resizing Gluster volumes with lookup-optimize enabled and I think it's worth sharing:https://access.redhat.com/solutions/5896761https://github.com/glust… @Sandro,Do you think it's worth checking and disabling that Gluster option on oVirt upgrade ? It might affect older setups that might still have it enabled. Best Regards,Strahil Nikolov

Deploy Hosted Engine with PowerFlex (formerly ScaleIO) storage
by twseagulls.kmj＠gmail.com 04 Nov '21

04 Nov '21

Hi This is the first time I have posted a question on here. I am attempting to deploy a Self Hosted Engine with RHV 4.4.8, RHEL 8.4 using a PowerFlex (ScaleIO) volume. I have done this several times in the past with oVirt 4.3.x and 4.4.? but for some reason on this occasion I am hitting a problem. I think I might know what it is but I don't know how to fix it. The deployment appears to go fine up until the point where the question is asked about which storage device I want the HE copied to, I select Fibre Channel but unfortunately this fails and does not find any suitable devices - I know that PowerFlex is not technically FC but the devices are recognised by multipathd and have always worked previously (I was instrumental in getting the udev rules changed in the PowerFlex 3.6 version to ensure the devices could be recognised by multipathd, whereas previously it had required a udev rules edit). The device I am trying to use is this: # multipath -v2 -l 1abc8aad74a6630f-c4c045df00000000 dm-2 ##,## size=120G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- #:#:#:# scinia 252:0 active undef running I can see in the log that the device is being partially discovered but it seems that a 'vendor_id' is wanted and this is something that udev does not report for a PowerFlex device. 2021-11-02 07:07:10,057+0000 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:112 TASK [ovirt.ovirt.hosted_engine_setup : Get Fibre Channel LUNs] 2021-11-02 07:07:10,960+0000 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:112 ok: [localhost] 2021-11-02 07:07:11,261+0000 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:106 PLAY RECAP [localhost] : ok: 5 changed: 0 unreachable: 0 skipped: 0 failed: 0 2021-11-02 07:07:11,362+0000 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:223 ansible-playbook rc: 0 2021-11-02 07:07:11,362+0000 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:230 ansible-playbook stdout: 2021-11-02 07:07:11,362+0000 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:233 ansible-playbook stderr: 2021-11-02 07:07:11,362+0000 DEBUG otopi.plugins.gr_he_ansiblesetup.core.storage_domain storage_domain._query_fc_lunid:379 {'otopi_fc_devices': {'changed': False, 'ovirt_host_storages': [{'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8ee e-60c8314b7e13/storage/19eadf533875920f-46da4fac00000000', 'id': '19eadf533875920f-46da4fac00000000', 'host': {'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8eee-60c8314b7e13', 'id': '80308d4a-ef91-40fd-8eee-60c8314b7e13'}, 'logical_unit s': [{'discard_max_size': 1048576, 'discard_zeroes_data': False, 'id': '19eadf533875920f-46da4fac00000000', 'lun_mapping': 0, 'paths': 1, 'size': 111669149696, 'status': 'free'}], 'type': 'fcp'}], 'invocation': {'module_args': {'host': 'pfxhci 14.hci.spoc', 'fcp': {'lun_id': -1}, 'fetch_nested': False, 'nested_attributes': [], 'follows': [], 'iscsi': None}}, '_ansible_no_log': False}, 'ansible-playbook_rc': 0} 2021-11-02 07:07:11,362+0000 DEBUG otopi.plugins.gr_he_ansiblesetup.core.storage_domain storage_domain._select_lun:398 [{'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8eee-60c8314b7e13/storage/19eadf533875920f-46da4fac00000000', 'id': '1 9eadf533875920f-46da4fac00000000', 'host': {'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8eee-60c8314b7e13', 'id': '80308d4a-ef91-40fd-8eee-60c8314b7e13'}, 'logical_units': [{'discard_max_size': 1048576, 'discard_zeroes_data': False, 'i d': '19eadf533875920f-46da4fac00000000', 'lun_mapping': 0, 'paths': 1, 'size': 111669149696, 'status': 'free'}], 'type': 'fcp'}] 2021-11-02 07:07:11,362+0000 DEBUG otopi.plugins.gr_he_ansiblesetup.core.storage_domain storage_domain._select_lun:407 [{'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8eee-60c8314b7e13/storage/19eadf533875920f-46da4fac00000000', 'id': '1 9eadf533875920f-46da4fac00000000', 'host': {'href': '/ovirt-engine/api/hosts/80308d4a-ef91-40fd-8eee-60c8314b7e13', 'id': '80308d4a-ef91-40fd-8eee-60c8314b7e13'}, 'logical_units': [{'discard_max_size': 1048576, 'discard_zeroes_data': False, 'i d': '19eadf533875920f-46da4fac00000000', 'lun_mapping': 0, 'paths': 1, 'size': 111669149696, 'status': 'free'}], 'type': 'fcp'}] 2021-11-02 07:07:11,362+0000 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-ansiblesetup/core/storage_domain.py", line 738, in _closeup lun = self._query_fc_lunid() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-ansiblesetup/core/storage_domain.py", line 395, in _query_fc_lunid return self._select_lun(available_luns) File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-ansiblesetup/core/storage_domain.py", line 418, in _select_lun 'vendorID': entry['logical_units'][0]['vendor_id'], KeyError: 'vendor_id' 2021-11-02 07:07:11,364+0000 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Closing up': 'vendor_id' 2021-11-02 07:07:11,364+0000 DEBUG otopi.context context.dumpEnvironment:765 ENVIRONMENT DUMP - BEGIN 2021-11-02 07:07:11,364+0000 DEBUG otopi.context context.dumpEnvironment:775 ENV BASE/error=bool:'True' 2021-11-02 07:07:11,365+0000 DEBUG otopi.context context.dumpEnvironment:775 ENV BASE/exceptionInfo=list:'[(<class 'KeyError'>, KeyError('vendor_id',), <traceback object at 0x7ff0f4e6da88>)]' 2021-11-02 07:07:11,365+0000 DEBUG otopi.context context.dumpEnvironment:775 ENV QUESTION/1/OVEHOSTED_STORAGE_DOMAIN_TYPE=str:'fc' Is there any way I can edit something to prevent this vendor_id being required?

Re: Issue upgrading VDSM in 4.4.9

Unfortunately I've already started running into broken dependencies when using the CentOS Stream Advanced Virtualization repos with RHEL. Since oVirt is now targeting Stream and packages are being pushed there, are RHEL and other EL8 clones not going to be supported by oVirt? Thank you. They are, and will be, supported, but it's lagging a bit behind Stream. The exact lag depends on how far are we from the next minor version. 4.4.9 will work on 8.5, there will be RHEL 8.5 and RHEL clones 8.5 soon, but there's not going to be CentOS 8.5, considering there's <2 months until CentOS EOL. So..for oVirt 4.4.9 you can say it's supported only on Stream. And It will be supported very soon on RHEL/clone. That said it will be probably a bit shaky once Stream 9 gets more traction. We will try to move to it whenever it starts working. And for that time until RHEL 9 releases there might be again some issues with RHELs.

Currently there's not much of a difference and if packages are installed happily then it likely works just fine, but with the upcoming RHEL 8.5 release it is unlikely CentOS would be updated to 8.5, so I'm afraid CentOS based systems won't last for too long. It would be best to move to Stream entirely, or use ovirt-node (as a snapshot of packages that work), or move to RHEL or RHEL clones. > > Thanks, > michal > > > > > # /etc/yum/repos.d/ovirt-4.4-stream-advanced-virt.repo > > [ovirt-centos-stream-advanced-virtualization] > > name=Advanced Virtualization CentOS Stream testing packages for $basearch > > baseurl=https://buildlogs.centos.org/centos/8-stream/virt/$basearch/advance… <https://buildlogs.centos.org/centos/8-stream/virt/$basearch/advancedvirt-co…> > > enabled=1 > > gpgcheck=0 > > module_hotfixes=1 > > _______________________________________________ > > Users mailing list -- users(a)ovirt.org <mailto:users@ovirt.org> > > To unsubscribe send an email to users-leave(a)ovirt.org <mailto:users-leave@ovirt.org> > > Privacy Statement: https://www.ovirt.org/privacy-policy.html <https://www.ovirt.org/privacy-policy.html> > > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ <https://www.ovirt.org/community/about/community-guidelines/> > > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/FNK5TJW7RWGUI… <https://lists.ovirt.org/archives/list/users@ovirt.org/message/FNK5TJW7RWGUI…> >

export to export domain concurrency

Hello, the export to export domain task is managed asynchronously. Does it support concurrency, so that I can export more VMs at the same time to the same export domain? If not by default, is there a parameter to enable it? The need would be on 4.4.7/4.4.8 based environments Thanks, Gianluca

Failed to delete snapshot

is disk reduce command while VM is active after snapshot deletion save?
by christian.peater＠gmx.de 03 Nov '21

03 Nov '21

When creating a snapshot, the volume gets two lv extents (2GB) . But after deleting the snapshot, the extents are kept and with every Snapshot creation the volume size increases. This is really annoying, especially when using snapshot for nightly backup. we are using oVirt 4.3.10 and we can't upgrade to 4.4 I have read that to shrink the volume the disk reduce command is what helps here, but the rest api documentation says, that this is only applicable while vm is not running. crazy as i am, i have called the reduce command while the vm was running, and it seemed to work. the volume has shrunk and the vm didn't crash. But is it save to do so? and why isn't the reduce command is called after deletion of a snapshot?

Importing default Grafana dashboards?
by Chris Adams 03 Nov '21

03 Nov '21

I upgraded a cluster to 4.4 (so really, reinstalled the engine with a backup and reinstalled all the hosts). I see the Monitoring Portal link to Grafana, but when I log in, there are no dashboards. Did I miss a step to import the default dashboard set? Is there a quick-and-easy way to do that? I've only barely poked at Grafana before, so not really sure what to do. -- Chris Adams <cma(a)cmadams.net>

Hi Tommy, You can apply the patches by changing the relevant files in engine and dwh and run 'engine-setup' or 'engine-setup --offline' . Steps: 1. connect to your engine machine 2. vi /usr/share/ovirt-engine/dbscripts/create_dwh_views.sql : add the new line as described in the patch: https://gerrit.ovirt.org/#/c/ovirt-engine/+/114565/4/packaging/dbscripts/cr… . 3. connect to your dwh machine (if the engine and dwh are on the same machine then all files are in the same machine) 4. create or edit the files in the patch: https://gerrit.ovirt.org/#/c/ovirt-dwh/+/114568/, note that for you files named 4_4 should be named 4_3 You can find the file's location with this command: find / -name *create_views_4_3.sql* 5. run engine-setup, or engine-setup --offline Let me know how it goes!

question about engine deployment success rate
by Henning Sprang 02 Nov '21

02 Nov '21

Hello, I've just inherited a project where we need to bring a prototype of a small Ovirt system (single node or 3 node hyperconverged, with glusterFS on the same machine, a bunch of different VM's ) running in an industrial machine into serial production. This means, we want to build a new 1 or 3 node Ovirt system each day up until 3 times a day. In my tests so far, the failure rate of the Ovirt engine deployment (via the included scripts as well as the web UI) turns out to be pretty high - it's between 40-60%, meaning until we have a running system, we would have to try the installation and/or final engine deployment about 2-4 times until we are successful. So far I could not identify clear error messages that let me tell how to fix the problem. Before going into details of the errors I would like to ask if people deeper into Ovirt would consider this a somewhat normal success rate, or if this indicates we are doing something generally wrong and we should definitely spend a few more hours or maybe days into finding sources of problems. More info about the system and errors * OVirt 4.3.9 (because the prototype was made and verified with that version - would be interesting to know, too, if it's strongly considered to upgrade for more stable installation/deployment) * The errors that appear are changing between the deployment process seeming not to be able to transfer the "LocalHostedEngine" VM to the glusterFS storage to become a "HostedEngine", and the other seems to be when the engine is already up and running, but never being really connected to the Ovirt system, continuously restarting, and also showing XFS filesystem errors in it's dmesg output. Any hints on our chances on getting this solved or requests for more information about the error are welcome - thanks in advance. Henning

New Install. 3 node HCI using 4.4.8 ISO
by shane.krenz＠gmail.com 02 Nov '21

02 Nov '21

Hello everyone. First time posting. Sorry if this is already been spoken to... I didn't see anything with a quick search that I did. 3 nodes running dual E5-2600 series V4 CPUs with 256G memory in a Hybrid storage config. 2x 1.9TB SSDs and 6x 600G SAS spinners attached to a SAS/SATA HBA. 4x 1G ports. During initial boot from the 4.4.8. ISO oVirt installer I set static IPs, added DNS entries and copied ssh keys copied to each host. First issue with deploying the cluster was complaining about partitions found on sdb even though I reclaimed and deleted everything on all drives. Ended up zero'ing the drives and started over. Then sdb was on the filter list. So I edited the LVM.conf file. now I am stuck on "Gluster brick_t is invalid, must be a file or device" No idea what to do about that one. Also, I am not sure if its actually pulling in the 600G 10k drives into the mix at all. How would I confirm this? First 1.9TB SSD drive Is where I am installing the OS. Should I change this to some other drive or usb stick and have the 2x SSDs as cache and all spinners as capacity data? not sure how all that is supposed to work as I am not too familiar with Gluster. I know Nutanix and vSAN pretty well. I wanted to try oVirt. I am having a MUCH harder time with initial setup. I appreciate any help / suggestions on best practice for my hardware setup.

The Engine VM (/32) and this host (/32) will not be in the same IP subnet.
by notify.sina＠gmail.com 02 Nov '21

02 Nov '21

Hi list, 'The Engine VM (10.200.30.5/32) and this host (10.200.30.3/32) will not be in the same IP subnet.' This happens when I select a static IP address configuration for the engine. Ive been struggling with setting up ovirt-hosted-engine on CentOS 8 servers in the Equinix network, using hosted-engine --deploy. Why would the setup not want the engine and the host it's being setup on, not be in the same subnet? Can someone please help me understand what prerequisites I am missing?

I have been working on getting this up and running for about a week now and I am totally frustrated. I am not sure even where to begin.

The first failure was the filter error, so I edited the /etc/lvm/lvm.conf to comment out the filter line. Then without doing a clean up I reran the deployment and got the above error.

Engine VM FQDN will not validate.
by admin＠foundryserver.com 30 Oct '21

30 Oct '21

Hello, I am trying to install the Hosted engine using the wizard. I am NOT using the hyper converged. When I add the fqdn of vmengine1.domain.com I get the error. localhost is not a valid address. When I add the host fqdn in the advanced area it validates, if I put the vmengine1.domain.com in the the host section it validates. Facts: - I have the domain in dns, confirmed by dig to resolve to the public IP of the host. - I have the domain in hosts file confirmed by using ping and dig - I have generated a ssh key for the root user on the host and I have added it to the known hosts file. - I have logged into via ssh to all forms of addressing, so the known hosts file has been updated. localhost ecdsa-sha2-nistp256 AAAA host1 ecdsa-sha2-nistp256 AAAA host1.localhost ecdsa-sha2-nistp256 AAAA vmengine.localhost ecdsa-sha2-nistp256 AAAA host1.domain.com ecdsa-sha2-nistp256 AAAA vmengine1.domain.com ecdsa-sha2-nistp256 AAAA The reading suggests that the error doesn't mean what it says, but something about ssh not able to login to the host. I have been able to login to the host with ssh manually from the cli. Any help would be greatly appreciated. thanks Brad

by jorgevisentini＠gmail.com 28 Oct '21

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.
