3 node cluster. Gluster for shared storage. CentOS8 Updated to CentOS 8 Streams :P -> https://bugzilla.redhat.com/show_bug.cgi?id=1911910 After several weeks .. I am really in need of direction to get this fixed. I saw several postings about oVirt package issues but not found a fix.

VG issue / Non Operational
by Christian Reiss 18 Jan '21

18 Jan '21

Hey folks, quick (I hope) question: On my 3-node cluster I am swapping out all the SSDs with fewer but higher capacity ones. So I took one node down (maintenance, stop), then removed all SSDs, set up a new RAID, set up lvm and gluster, let it resync. Gluster health status shows no unsynced entries. Uppon going from maintenance to online from ovirt management It goes into non-operational status, vdsm log on the node shows: 2021-01-17 11:13:29,051+0100 INFO (jsonrpc/6) [api.host] START getAllVmStats() from=::1,48580 (api:48) 2021-01-17 11:13:29,051+0100 INFO (jsonrpc/6) [api.host] FINISH getAllVmStats return={'status': {'message': 'Done', 'code': 0}, 'statsList': (suppressed)} from=::1,48580 (api:54) 2021-01-17 11:13:29,052+0100 INFO (jsonrpc/6) [jsonrpc.JsonRpcServer] RPC call Host.getAllVmStats succeeded in 0.00 seconds (__init__:312) 2021-01-17 11:13:30,420+0100 WARN (monitor/4a62cdb) [storage.LVM] Reloading VGs failed (vgs=[u'4a62cdb4-b314-4c7f-804e-8e7275518a7f'] rc=5 out=[] err=[' Volume group "4a62cdb4-b314-4c7f-804e-8e7275518a7f" not found', ' Cannot process volume group 4a62cdb4-b314-4c7f-804e-8e7275518a7f']) (lvm:470) 2021-01-17 11:13:30,424+0100 ERROR (monitor/4a62cdb) [storage.Monitor] Setting up monitor for 4a62cdb4-b314-4c7f-804e-8e7275518a7f failed (monitor:330) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 327, in _setupLoop self._setupMonitor() File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 349, in _setupMonitor self._produceDomain() File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 159, in wrapper value = meth(self, *a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 367, in _produceDomain self.domain = sdCache.produce(self.sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 110, in produce domain.getRealDomain() File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 51, in getRealDomain return self._cache._realProduce(self._sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 134, in _realProduce domain = self._findDomain(sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 151, in _findDomain return findMethod(sdUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/sdc.py", line 176, in _findUnfetchedDomain raise se.StorageDomainDoesNotExist(sdUUID) I assume due to the changed LVM UUID it fails, right? Can I someone fix/change the UUID and get the node back up again? It does not seem to be a major issue, to be honest. I can see the gluster mount (what ovirt mounts when it onlines a node) already, and gluster is happy too. Any help is appreciated! -Chris. -- with kind regards, mit freundlichen Gruessen, Christian Reiss

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

Q: Node SW Install from oVirt Engine UI Failed
by Andrei Verovski 18 Jan '21

18 Jan '21

Hi, I installed fresh CentOS Stream on HP ProLiant and now trying to install Node SW from oVirt Engine WEB UI. Software installation failed but no comprehensive description displayed in WEB UI. Where I can find detailed logs what’s going wrong? On node "sudo dnf repolist —all” lists required repos, with unnecessary disabled. Thanks in advance.

About Translation

18 Jan '21

Hello, I'm Reyhan! I am a third-grade physics engineering student in Turkey, I also worked as a part-time system administration in the university's IT Head Office until last month. (Now I'm more into DevOps). Back in there, I was responsible for understanding how we can apply oVirt to our IT Office, so I was scrolling through the documentations. I've decided to contribute, oVirt could be the project I used the most, since I'm not a bug-fixer, at least I can help with the translation. I'm a native Turkish speaker, so I thought it would go well. I wish you the best, Best regards. Reyhan Gülçetin.

how to install hosted-engine without internet connection ?
by tommy 18 Jan '21

18 Jan '21

Hi,every one! My env cannot access internet, but during the hosted-engine installation, It needs to run yum install to update system. I have made a yum source mirror local, but there is a step ( after create engine vm, the vm runs yum update using default repo configure ) it failed to connect yum source. How can I configure yum source to local yum server before the vm run update ? Thanks.

This time I setup a bridge BR0 and disable EM1 (the first Ethernet interface on the host), and then created Bond0 on-top of BR0. Both Bond0 and EM2 (the second Ethernet interface on the host) were up. And then I tried again using Ovirt-Cockpit wizard, with the Engine VM set on BR0, and the deployment of Engine VM simply failed.

Disaster Recovery using Ansible roles
by Henry lol 17 Jan '21

17 Jan '21

Hi, I have 2 questions about Disaster Recovery with Ansible. 1) regarding Ansible failover, AFAIK, a mapping file must be generated before running failover. then, should I periodically generate a new mapping file to reflect the latest structure of the environment? 2) I guess Ansible failover uses OVF_STOREs to restore the environment and OVF_STOREs in storage domains are updated every 1 min as default. then, how to recover the changes made in the meantime?

Hyperconverged Ceph + Managed Block Storage
by Shantur Rathore 16 Jan '21

16 Jan '21

Hi all, I am planning my new oVirt cluster on Apple hosts. These hosts can only have one disk which I plan to partition and use for hyper converged setup. As this is my first oVirt cluster I need help in understanding a few bits. 1. Is Hyper converged setup possible with Ceph using cinderlib? 2. Can this hyper converged setup be on oVirt Node Next hosts or only Centos? 3. Can I install cinderlib on oVirt Node Next hosts? 4. Are there any pitfalls in such a setup? Thanks for your help Regards, Shantur
