Issues with resizing Gluster Volumes with sharding and lookup-optimize enabled

by Strahil Nikolov

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/glu... @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

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

by Michal Skrivanek

Hi Thomas, > On 4. 11. 2021, at 0:40, Thomas Simmons <twsnnva(a)gmail.com> wrote: > > Hello Michal, > Yes was running official RHEL 8.4 on my hosts and have also tried with Rocky. 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.

I am running into the issue on one of the inital steps (yum/dnf install cockpit-ovirt-dashboard vdsm-gluster ovirt-host). After some digging, I found that the version of libvirt that it's looking for (libvirt >= 7.6.0-2) is not in the CentOS 8 Advanced Virt repo, but is only in the CentOS Stream Advanced Virt repo. > > > > You can see here that libvirt 7.0.0-14.1 is the latest available in the CentOS 8 Advanced Virt repo: > > > > http://mirror.centos.org/centos/8/virt/x86_64/advanced-virtualization/Pac... <http://mirror.centos.org/centos/8/virt/x86_64/advanced-virtualization/Pac...> > > > > However, the newer libvirt 7.6.0-2 is available in the 8-stream repo: > > > > http://mirror.centos.org/centos/8-stream/virt/x86_64/advancedvirt-common/... <http://mirror.centos.org/centos/8-stream/virt/x86_64/advancedvirt-common/...> > > > > I don't know if there will be any ramifications down the road (I'm hoping there will not be since Stream tracks just behind the next EL point release), however I was able to get past the error by adding the 8-stream Advanced Virt repo to my systems by creating the repo file below. It would be nice if a developer could respond and advise if this is a "safe" solution, or if this is a known problem that they expect to address? > > Hi, > qemu/libvirt packages are now being pushed to Stream, CentOS is supposedly EOL in 2 months. 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/advan... <https://buildlogs.centos.org/centos/8-stream/virt/$basearch/advancedvirt-...> > > 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/FNK5TJW7RWG... <https://lists.ovirt.org/archives/list/users@ovirt.org/message/FNK5TJW7RWG...> >

add users to group

by Nathanaël Blanchet

Hello, The only way I found to add users to group is : ovirt-aaa-jdbc-tool group-manage useradd /|group-name|/ --user=/|username|/ I didn't find any way to do such a thing neither with the webui, neither with ansible module ovirt_group or ovirt_user.

export to export domain concurrency

by Gianluca Cecchi

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

by ivohccarvalho＠gmail.com

Hello all. We use vprotect to make snapshot backups of our vm's. This VM, let's call it OVIRTVM, has it's disks created as thin. A full snapshot is created daily on sunday and the daily ones are incremental.

is disk reduce command while VM is active after snapshot deletion save?

by christian.peater＠gmx.de

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

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>
