oVirt 4.3 - Fibre Channel Data Domain as ISO dump.
by Angus Clarke 14 Feb '22

14 Feb '22

Hello RE: oVirt 4.3 - Fibre Channel Data Domain as ISO dump. Thanks for letting me join the list. I added a fibre channel Data domain with a view to using it as an ISO dump however I cannot mount CDs to VMs with this error: "Error while executing action Change CD: Drive image file could not be found" A bit of reading suggests there is no way around this when using fibre channel data domains - is this the case? I guess I could present the LUN to a VM and run NFS from there as an alternative option. Thanks a lot Angus

RHGS and RHV closing down: could you please put that on the home page?

I just read this message: https://bugzilla.redhat.com/show_bug.cgi?id=2016359 I am shocked but not surprised. And very, very sad. But I believe this decision needs to be communicated more prominently, as people should not get aboard a project already axed.

Hi, I see a lot of errors in vdsm.log 2022-02-14 08:42:52,086+0100 ERROR (mailbox-spm) [storage.MailBox.SpmMailMonitor] mailbox 65 checksum failed, not clearing mailbox, clearing new mail (data=b'\xff\xff\xff\xff\ <lot of data> \x00\x00', checksum=<function checksum at 0x7f2454712b70>, expected=b'\xbfG\x00\x00') (mailbox:602) 2022-02-14 08:42:52,087+0100 ERROR (mailbox-spm) [storage.MailBox.SpmMailMonitor] mailbox 66 checksum failed, not clearing mailbox, clearing new mail (data=b'\x00\x00\x00\x00\ <lot of data> \xff\xff', checksum=<function checksum at 0x7f2454712b70>, expected=b'\x04\xf0\x0b\x00') (mailbox:602) We are running latest ovirt engine and hosts: Hosts: ovirt-node-ng-installer-4.4.10-2022020214.el8.iso engine: ovirt-engine-4.4.10.6-1.el8.noarch We have 3 hosts and 8 iSCSI domains.

Can anybody help me please? I observed the issue prior we upgraded to v4.4 (I hoped the upgrade will fix it, but it does not)

what are the steps to swap/upgrade/reboot my main storage domain with minimum downtime
by Pascal D 14 Feb '22

14 Feb '22

I need to upgrade my main domain storage (NFS) which hosts 100s of VMs and templates including the hosted engine. Can I put the data center in global maintenance, do a quick sync and swap of the domain storage and bring it back up without missing a beat?

Hi, I want to deploy ovirt-csi in the kubernetes cluster. But the guide only has how to deploy to openshift. How can I deploy the ovirt-csi in the kubernetes cluster? Is there any way to do that?

Fibre Channel storage issue
by Timothy J. Wielgos 10 Feb '22

10 Feb '22

Thanks everyone for helping me through the last issue I had. Once I changed bonding mode to 2, everything worked. However, now I have another issue. I'm trying to install this using fibre channel storage. I set up a new lun from my storage array, assigned it to my host, and configured multipathing. All looks good. Then, when I ran the install script, I got the following error: [ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Physical device initialization failed. Please check that the device is empty and accessible by the host.]". HTTP response code is 400.[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Physical device initialization failed. Please check that the device is empty and accessible by the host.]\". HTTP response code is 400."} Google says that's because the lun is dirty - maybe reused. I tried doing the suggested - I used dd to write all zeroes to the lun. I used wipefs on the lun. I deleted the lun from the array and created a new one. No matter what I did with that lun, it's still showing up with this error. I then created a second LUN. I mapped it to the host, and attempted to use that lun for storage - and it worked! There must be a dirty config somewhere on this thing that I need to clean up from that first lun. Anybody know what I might have to clean up on this host to clear out that old config?

OVIRT-Node Engine Deployment Failure due to no URLs in mirrorlist
by aellahib＠gmail.com 09 Feb '22

09 Feb '22

I am running OVIRT-Node and although I updated my mirror list and the hosts are fine. It seems my engine deployment (deploying hyperconverged gluster) is trying to use a different set of mirrors during Engine VM Prep. SO this is the error I see, should I be running a newer RPM on these nodes or something, I am not aware if there is a newer one I should be using for this. [ INFO ] TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package] [ ERROR ] fatal: [localhost -> 192.168.222.193]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'ovirt-4.4-centos-gluster8': Cannot prepare internal mirrorlist: No URLs in mirrorlist", "rc": 1, "results": []} [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Sync on engine machine] [ INFO ] changed: [localhost -> 192.168.222.193] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set destination directory path] [ INFO ] ok: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Create destination directory] [ INFO ] changed: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Find the local appliance image] [ INFO ] ok: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set local_vm_disk_path] [ INFO ] ok: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Give the vm time to flush dirty buffers] [ INFO ] ok: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Copy engine logs] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Notify the user about a failure] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "There was a failure deploying the engine on the local engine VM. The system may not be provisioned according to the playbook results: please check the logs for the issue, fix accordingly or re-deploy from scratch.\n"} It does let me click PrepareVM despite Deployment Failed -- but at that point /var/tmp is filled to more than 67% so it fails due to no space for engine install despite the good minimum requirements set lol

What replaces ISO domains how to re-use ISO files on multiple Data Centers?
by Brian Levinsen 08 Feb '22

08 Feb '22

Hello. I have been searching but not been able to find a solution. As far as I could find the Storage Domain Type ISO is deprecated. We have used this for hosting one central location for ISO images. Everywhere I found they say to use a Data Domain. But a Data Domain can not be attached to multiple Data Centers? So how do we in newer versions of ovirt share ISO files with multiple Data Centers? /Brian
