@jan010 Sorry for not following up, but yes, I did actually track down my issue. It's likely not your issue, but for some reason my network interface in `/etc/network/interfaces` had an additional `:254` or `:255` (I can't quite remember) tagged on to the end of the vlan. I'm not sure how and...

I'm also experiencing this with the same hardware: `Broadcom NetXtreme II BCM5716` For me the issue happened when upgrading from Kernel 6.2 to 6.5.

@showiproute Thanks for this We were wondering if such a configuration was possible but did not investigate it further when we found the m.2 to the u.2 adapter.

We have recently realized (as many others on this forum eventually realize) that our consumer grade SSDs just aren't cutting it when it comes to everyday IOPS performance: Terrible random write IOPS below 20 using the proxmox zfs benchmark tests System load spikes when running all our VMs...

I just wanted to follow up on this since i was able to pinpoint the issue to slow sync writes and iops on my samsung qvo 870 drives (as was predicted by others earlier in this and other posts). I'm still not sure why the load averages started increasing significantly a few months ago, but if I...

@spleenftw could you report what `pveperf` shows? For me my `Fsyncs` is consistently under 20 (even slower than my old rust disks).

Thanks for following up. If you haven't come across this, it may be worth a try for you: https://www.reddit.com/r/Proxmox/comments/dufmli/terrible_disk_write_speed_on_zfs_mirrored_ssds/ Unfortunately I didn't have any bios options to enable/disable the write cache on the controller on my system.

That is probably the case. The thing that I don't understand is why the large change in performance on the SSD machines. The average load went from 1-2 up to 7-8. Even light workloads now seem to cause high load. File transfers from the vms often drop to just a few MB/s (under 10MB/s) without...

@Dunuin No. We have 3 nodes. Two with SSDs that are showing the issue and the other is a 10k HDD not displaying the issue.

@spleenftw Have you made any other progress on this? We are seeing a very similar situation on two of our cluster nodes. High I/O Wait and system Load. It doesn't seem to matter which VMs are running on those nodes, the more VMs the higher the load, but the load is MUCH higher than it was about...

Yes I'm still using this setup with a few very minor tweaks. Let me save you some hassle and paste my notes here :) ``` Disk Setup Wipe Disk A disk can be wiped in the proxmox (not proxmox backup server) GUI, by simply navigating to: node > Disks > Select Disk > Wipe Disk. Alternatively, the...

@dcsapak Friendly reminder: Were you able to find out if the patches were applied (or if they will be applied soon)? As of 7.4-16 it looks like the tar option is still removed when selecting any files/directories.

@dcsapak Do you know if tar downloads are still planned? I'm still seeing what @hmalzahn was seeing (the tar option initially appears but is gone when selecting individual files/folders) The tar download option will be a great improvement since the zip downloads don't handle simlinks. This has...

@timdonovan and @batrovich I haven’t tested it but there’s a chance this same solution could work for you. You would want to find the path of the disk that is used for the vm and run the same command with that path.

To follow up on this one more time, i discovered that the backup wasn't working because `.chunks` was missing from the dataset. It appears that the '.chunks' was removed when mounting the zfs pool onto the /backups directory. To fix this, I allowed proxmox to create a dataset when creating the...

@noel. To shed some more light on this, my datastore is mapped to /backups. I'm not sure if it's supported, but I mount an external drive to /backups using zpool import backups (The 'backups' zpool was created using the pbs web UI and was given a mountpoint like: zfs set mountpoint=/backups...

I'm also seeing this same issue. In the past i was able to at least get the backups to work by using the root pbs user, but now i get the same `Permission denied (os error 13)` error when trying to run any backups. I've also tried creating a separate user on the pbs machine and giving it...

@hanse Maybe update to PVE 7.2 This is what i'm talking about:

If you don't want to install the extra drivers, you can try to use an IDE SATA Drive instead of the VirtIO. Also for networking you can use the E1000 type instead of VirtIO. Once you have Windows up and running, then you can log in and install the VirtIO drivers easily by downloading them with a...

@vklabs Did you ever find a solution? I'm experiencing the same issue. I can SSH into the VM without any issues and the Proxmox logo shows in the console when rebooting the VM, but after displaying "Connected (encrypted) to QEMU (nextcloud)" it goes to a blank/black screen. I do see the...
