I'm still unsure what you mean?
Maby that i should wait to migrate, until the VM "Has no errors"?
And yes, I'm not migrating until I get the migration process to work. :)
Hi again.
I removed the version of Virtio and installed the one you suggested. + i changed the SCSI controller to Virtio Single SCSI.
What i end up with, it a "Inaccessable boot device".
Then it boots in automatic repair mode.
Hey, thanks a lot for reporting this!
I have managed to reproduce the issue. As you mentioned, v8 does not seem to have this problem, but v9 does.
A build of the latest Git repositories also has this problem, so it has not yet been patched...

Hi, new here and didn't find this thread before posting my own. ( https://forum.proxmox.com/threads/lets-talk-deduplication-and-immutability.182803/ )

Maybe the the IO-Wait gets so high that corosync drops out or the Watchdog gets triggered?
You could try to set a bandwidth limit in the backup job or a fleecing storage?
Hello,
Thank you for your response. Is the version now available?
Thanks again, @j.theisen, for the quick diagnosis you provided via the ticket.
I won’t hide the fact that I had to switch to prioritizing the entire VLAN via TC and disable the...
Thanks, this is very useful. As we developed for clouds until now, we did not need a local lab. It is difficult to build one since we do not own a datacenter but I would like to rent some lab where I can test and debug our integration with...
Thank you for your insights!
That's a very good point regarding the possibility that the I/O error could be occurring at the QEMU layer rather than in the FC, multipath, or LVM stack.
I also agree that moving the backup window to Saturday would...

Thank you for your suggestion!
That's a good point. I'll check with our backup team to see whether it's possible to move one of the affected VMs to a different backup day so we can observe whether the issue still occurs. I'll gather more...
