Backup prozess
by marcel d'heureuse
Moin,
We have in our Environment 12 servers managed by one self hosted engine. It is ovirt 4.3.9. We are Freizeit on that Version.
How did you make Backups? We use a github Script which generate via api a snapshot and Mount this disk into the vm where the backup Script is running. The backup Script Export this additional Hard disk to a storage and disconnect the disk and remove the snapshot.
This works on Linux vm fine if they have Medium load. If we try this with a Windows 10 vm or Windows Server vm or a Linux vm with high load or with a very big Hard drive this will not work. Disk can't Export and snapshot will not delete.
I have found winchin and bareos but I have not start to check this first I want to have some more possible options.
Thanks

This works since 4.4.6, but was broken in 4.3. You should upgrade to
4.4 at this point.

Yes NFS works for ISO on data domain in 4.3.

oVirt 4.3 - Fibre Channel Data Domain as ISO dump.
by Angus Clarke
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

ERROR (mailbox-spm) [storage.MailBox.SpmMailMonitor] mailbox 65 checksum failed, not clearing mailbox, clearing new mail
by Petr Kyselák
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)

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. I found similar issue from 2018 https://lists.ovirt.org/archives/list/users@ovirt.org/thread/FJ6KIEOXEEFF...
I am not sure how to determinate which mailbox I should try to "clean". 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)

Upgrade CentOS 7 oVirt host to CentOS 8 Stream from backup file - Python error
by Matyi Szabolcs
Hi Support,
The following is the problem.
I am trying to upgrade a CentOS 7 oVirt host to CentOS 8 Stream with oVirt-engine backup.
https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3
I perform the reset as follows:
hosted-engine --deploy --restore-from-file=/path/to/backup
When ansible-playbook is almost finished it gives the following error:
