HA Broker corrupting iSCSI Lockspace
by mblecha＠techmerx.com 14 Sep '24

14 Sep '24

I'm not sure how it happened, but a few hours ago, the lockspace for the hosted engine became corrupted. sanlock reports a -223 error. CentOS 8 Stream, Ceph iSCSI backend (Reef at 18.2.4) using tcmu-runner. I managed to format the lockspace, after shutting down the HA Agents and Brokers on all HA Engine nodes, but as soon as I start up the HA Agent on any node, the lockspace becomes corrupted again, and sanlock starts returning the -223 error message again. I see no relevant other errors in what I can find so far. Any suggestions on where to investigate next? I have an entire cluster than cannot start/stop/migrate VMS as the entire DataCenter is marked Non Operational.

Moving hosted engine to iscsi storage domain
by Devin A. Bougie 13 Sep '24

13 Sep '24

Hello, We are attempting to move a hosted engine from an NFS to an iSCSI storage domain, following the normal backup / restore procedure. With a little intervention in the new hosted engine VM, everything seems to be working with the new engine and the process gets to the point of trying to create the new iSCSI hosted_storage domain. At this point, it fails with "Storage domain cannot be reached. Please ensure it is accessible from the host(s).” The host itself does see the storage, and everything looks fine using iscsiadm and multipath commands. However, if I look at the new hosted_storage domain in the new engine, it’s stuck “unattached” and the “hosted-engine --deploy --restore-from-file …” command loops at the "Please specify the storage you would like to use” step. Please see below for an excerpt of the output and logs, and let me know what additional information I can provide. Many thanks, Devin Here’s the output from the “hosted-engine --deploy --restore-from-file …” command. ——— [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : iSCSI login] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get iSCSI LUNs] [ INFO ] ok: [localhost] The following luns have been found on the requested target: [1] mpathm 1024.0GiB IFT DS 3000 Series status: free, paths: 8 active Please select the destination LUN (1) [1]: [ INFO ] iSCSI discard after delete is disabled [ INFO ] Creating Storage Domain [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Execute just a specific set of steps] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Force facts gathering] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for the storage interface to be up] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Check local VM dir stat] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Enforce local VM dir existence] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Obtain SSO token using username/password credentials] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch host facts] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch cluster ID] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch cluster facts] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch Datacenter facts] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch Datacenter ID] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch Datacenter name] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch cluster name] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fetch cluster version] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Enforce cluster major version] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Enforce cluster minor version] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set storage_format] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Add NFS storage domain] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Add glusterfs storage domain] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Add iSCSI storage domain] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Add Fibre Channel storage domain] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get storage domain details] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Find the appliance OVF] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get ovf data] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get disk size from ovf data] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get required size] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Remove unsuitable storage domain] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Check storage domain free space] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Activate storage domain] [ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed".

ovirt hosts unassigned
by dragons＠namecheap.com 11 Sep '24

11 Sep '24

Hello, we have found ovirt hosts in unassigned states after renewing certificates for oVirt engine via engine-setup --offline. The first launch ended with an error. We had an immutable attribute on the file /etc/pki/ovirt-engine/keys/engine_id_rsa After which we removed the attribute and launched again engine-setup --offline. In the events for each host we see the following errors: VDSM ov3.example.com command Get Host Capabilities failed: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target Is there any way to return the host to normal without losing data?

Hi Marcos, thank you so much for your feedback and clarification. I've recognized you are a big player in the Oracle Universe; we are currently migrating from Oracle VM Server to Oracle Linux Virtualization Manager. the target was to include also some other Servers from VMware Hypervisor.

Dear All, In our Ovirt Engine Infrastructure, recently we have received an alert for one of our "Storage Domain" The alert is as mentioned below---- =================================== Storage domains with IDs [fb34e5b7-e850-4d66-ab47-3011d2000338] could not be synchronized. To synchronize them, please move them to maintenance and then activate. ========================================================== What is the consequence of this alert, if we ignore this what can happen to the infra, are we going to face any issue with the VMs, currently this infra is under production

Hosted Engine Boot Failure Recovery Guidance
by Clint Boggio 05 Sep '24

05 Sep '24

Good Day oVirt Community I've experienced a condition whereby the HE on my three-node cluster will not boot. Connecting to the hosted-engine console reveals that the hosted engine is in the "grub rescue" prompt. I don't really know how to rescue the engine from that level of failure but if anybody can give me a quick set of steps to maybe cover that engine I'd appreciate it and certainly give it my best try. If it's easier to re-deploy the engine and leverage a backup file in the process I have such a backup file created yesterday readily available. I would need a link to a process for decommissioning the dead machine, and re-deploying the replacement HE from the backup file. Any help would be greatly appreciated.
