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 Marcel

Hi Sandro, It seems that with https://github.com/oVirt/ovirt-site/commit/f3286b2e1f2871978d054250556f1b4f… all refference to Gluster & Hyperconverged is removed from the website. Can you clarify the situation with Hyperconverged deployments ? Best Regards,Strahil Nikolov

This works since 4.4.6, but was broken in 4.3. You should upgrade to 4.4 at this point. > I guess I could present the LUN to a VM and run NFS from there as an alternative option. Yes NFS works for ISO on data domain in 4.3. Nir

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. I found similar issue from 2018 https://lists.ovirt.org/archives/list/users@ovirt.org/thread/FJ6KIEOXEEFFZS… 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)
