@broth-itk I appreciate the note. Please flag any issues you find on GitHub, or improve and make a pull request.

no, there isn't. but keep in mind that almost all repositories are append-only, so each snapshot only takes the space for modified indices + added packages.
Since we have confirmed that no issues occur with the LSI 9500-16i Tri-Mode HBA, I believe testing with the SAS3808 (LSI 9500-16i) or SAS3816 (LSI 9500-8i) operating in IT mode would not be meaningful.
* I use the LSI 9500-16i and LSI 9400-16i...
Meh. Another example why these "bullshit as a service"-providers are actually not that helpful. Depending on your usecase, regulations and operating systems stop might actually be more safe. Both variants have their own up- and downsides. It...

What speeds do you expect?
I think that 3GB/s per second is already pretty fast.
What is your target speed you aim at?
Is the current speed a problem? Or are you just surprised that you can't reach line speed and suspect an issue with your setup...
All of them work they just have different impact on the downtime of said service:

Basically stop mode gives the highest consistency but will introduce a downtime for making the...
@nadirian , great! Congratulations! :)
A snapshot preserves only the difference between the state in the moment of creating it and the current state.
It is useless if you lose the VM/CT.
Contrary, backups are self-sufficient (of course the...
Hi ! Yes , you're right! Silly of me. I got confused about the size of the backup seemed "same as size of the VM".
So how do i make a proper backup? I get "Snapshot, Suspend and Stop" as alternatives when i want to "backup" a machine. :)
AFIK you can easely test this. Just start two backups at the same time. Then run it again. Now it should be 100% dublicates and you are only benchmarking SHA256
That is exactly my guess.
3,6GBit/s is pretty far away from your goal of 10GBit/s...
Imho you don't get much that way because at some point the kernel 6.17 won't get this updates anymore. So imho pinning proxmox-default-kernel gives a kind of wrong security feel. But to be honest in the end it boils down to personal preference...
When VMs are getting backed up with Proxmox VE native backup methods, VMs will continue to fully run during the backup.
3rd party vendors can utilize the public backup API. Then things work the same. If they use a custom implementation under the...

Thought I would document this down in case anyone has tried to do this but again had no luck getting answers.
TLDR: Use a VM for anything GPU/pass through related.
The reason I was digging into this first was because I wanted to run a LLM on my...
So we've tried to reproduce it on a test system provided to us, but couldn't so far.
Could you detail your setups, the workload and any steps necessary to trigger this?
Second test was on the PBS.
Not sure if I can follow.
I would even argue that the culprit is both CPUs.
The first clear bottleneck seems to be TLS.
I gave you 4 parts of TLS.
We can rule out 1.
According to you, we can also rule out 2.
For 3...
i repeat, dont use the test-repo for production.
developers state its only for testing-purposes and not for production-use as evidenced by my screenshot from their own wiki.
you ignoring this is purely on you and on noone else.
you could have run...
