ok just a small update on the issue. I have just finished updating the firmware on the i226-v card from version 2.23 to version 2.25 in the hopes that it will fix the issues of very slow performance. The update went successful and all 4 ports reports the firmware version is now 2.25 but...

great guide meyergru. Will keep it in mind. Thanks.

Yes try stay away from realtek too since (at least) some models they do not have great support under Linux and they start having issues when push to their limits. Chears Phanos

Hi leannaki, glad that I see you find a solution to your issue. However disabling IOMMU in Proxmox/Virtual environment is not the best idea since disabling IOMMU it will introduce a number of limitations including the ability to pass-though pci devices to VMs in the future.

Hi leonnaki, I have replaced the i226-v card with an old 82576NS Gigabit Network card that I had home. This card has only two network ports (1Gbit each) but since my ISP is only 1GB and I really only need two network ports at the moment it suffices for now. After replacing the i226-v and even...

I am running latest proxmox 9 VE (latest updates) on a i7-8700T cpu, 16GB ram and 1TB nvme hard drive. I have install in the proxmox machine a quad 2.5 GB i226-v network adapter for using it in a opnsense vm but I am unable to get any performance from that card. I have tried both pci...

I will have that in mind for future. thanks!!

For anyone that will come here having the same issue I am reporting that I was able to fix the issue by replacing the crucial ssd with a Samsung 870 evo 1TB ssd. I know this hard disk is way better than the original ssd that I had (and I would probably would have gone away with a simpler less...

I have install more than 5-6 proxmox installs over the years like this and it was okish until now. and now maybe the issue is elsewhere but I will keep what you say in mind. If I install proxmox directly from the proxmox iso do I have the same packages available (to install later) that I get...

I have been running proxmox for many years now and this is how I make it on my first machine so I keep on installing it like this. First installing Debian and then proxmox. Do you think I loose something like this?

will test to make sure

Will do @leesteken thanks. I have already order a temporary drive (tlc nand) to test and if everything is find I will invest in an enterprise level drive. QLC is really bad but I did not realize that it could be so bad..

@leesteken I have not run memory test yet but please note that every time I try to write something big to disk this happens. It seems that the issue is consistent to disk write and only after a write have been initiate for a few seconds the issue starts to occurred. Otherwise the VMs run for...

Hi @leesteken, no errors on hosts at all. Host is only being slowed down and then recovers after a while. Only the VMs are affected. Some need only reboot, some need to be restored from backup since they are getting so corrupted that can not even boot afterwards. But this only happens when I try...

ok @_gabriel thank you for the help. Will wait for the new drive to test and report back.

Hi @_gabriel , disk is not full, is brand new, only around 120 GB out of 500GB is written. I mean using the proxmox build in backup/restore feature. I backup my VMs on a network storage and then use this backup image to restore them on the new proxmox host. Both host run latest Proxmox 8.xx...

Thanks @_gabriel I will try to get a new drive and try again again but I am not 100% sure the ssd is the real culprit here. What if I get a faster disk drive and simply put more VMs on my host? Will the problem re-appear? If the proxmox host would give any kind of error I would say it is 100%...

Thanks but are they really that bad? I had run proxmox on mechanical drives in the past and never had issued with it. I also run it on my old machine on slower SSDs (without dram less also but other brands) and had no issues either. How can an ssd produced such errors when under some stress. I...

Hi I have upgrade my old proxmox server (an atom C2550 cpu) to an intel Xeon CPU. Specifically I have a now 1) Supermicro X11SSM-F motherboard, 2) Intel xeon E3-2145L v5 CPU 3) 64 GB ram 4) 512 SSD disk (CT500BX500SSD1) -- I know this disk is dramless and it is not fast but I am not sure if...
