Random disconnection USB3 and/or NVME HDD containing the Host (PVE 8.1.10)

Also, I found this in your 5/10 post:

Mar 29 07:21:10 pve kernel: usb: port power management may be unreliable

Look into the power saving stuff in your BIOS, and you may have to echo some stuff into /sys/bus to prevent the USB ports from getting powerdown "savings". From what I saw you have a crazy amount of usb ports

Mar 29 07:21:10 pve kernel: hub 1-0:1.0: 16 ports detected
Mar 29 07:21:10 pve kernel: hub 2-0:1.0: 10 ports detected
 
Thank you for your help, the HP micro server was purchased on Amazon Renewed and is guaranteed for another two months (yes, it's reconditioned) but personally, I really don't think the problem is hardware.

As for the PCIe/USB3 adapter, it's a mini PC, there is no second PCe port for data.

HP EliteDesk 800 G3 Desktop Mini Business PC
  1. 1 Turbo drive (M.2 PCIe) M.2 PCIe x1-2230 (for WLAN)
  2. 1 Turbo drive (M.2 PCIe) M.2 PCIe x4-2280 (for storage)

For the suggestion to upgrade to 2.5Gb, my NAS only has one 1GB Ethernet port and all these other USB ports are occupied and I'm not even sure it would accept a USB3/2.5GB adapter. This isn't a solution I'm going to pursue, but thanks for the suggestion.

Disabling power management is one of the first things I disabled in the BIOS during the initial install, but I'll double-check by connecting an external display, maybe I missed a little something else. Thank you for this reminder.

What I don't understand is that the hard drive is in use when it disconnects, if power management was enabled it should not disconnect the hard drive (Frigate reads and writes constantly).

Also, autosuspend is disabled by default in the kernel since 2.6, from what I understand, so it doesn't come from there (I don't use a HUB).

When in doubt, In order to completely disable LMP USB3 after reading this topic

https://askubuntu.com/questions/802712/how-to-disable-usb3-lpm-hardware-controlled-power-management

I just updated the kernel to version 6.5.13-5-pve.

Code: 
root@pve:~# pveversion
pve-manager/8.1.10/4b06efb5db453f29 (running kernel: 6.5.13-5-pve)

I also made these changes in GRUB

Code: 
nano /etc/default/grub
Replace
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
by
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on usbcore.quirks=0480:a200:k,18d1:9302,k"
update-grub
reboot

After:
Code: 
root@pve:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.5.13-5-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on

Before reboot:
Code: 
root@pve:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.5.13-5-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on usbcore.quirks=0480:a200:k,18d1:9302,k

I had already read this article and from what I understood to the contrary, this activates automatic deactivation which is disabled by default.

You have to set 0 to deactivate it but it doesn't work

Code: 
root@pve:~# echo "0" > "/sys/bus/usb/devices/2-3:1.0/power/autosuspend_delay_ms"
-bash: /sys/bus/usb/devices/2-3:1.0/power/autosuspend_delay_ms: Permission denied

Code: 
root@pve:~# cat /sys/bus/usb/devices/2-3:1.0/power/control
cat: '/sys/bus/usb/devices/2-3:1.0/power/control': No such file or directory

In the meantime, I just connected an external screen to control the BIOS, the power saving function was all disabled.
I took the opportunity to update the BIOS, you never know, it went from version v02.47 to v02.49.

I will now wait a few days to see how the system behaves before continuing to make any further modifications.
Thanks for your help.

After 4 days and 11 hours, I just had a disconnection / reconnection of the CORAL USB TPU (not the HDD), maybe this will happen in 2 days, to see...

In this case, the GOOGLE CORAL USB TPU reconnects automatically, so it is not a problem, but that will not be the case for the Hard Drive which will not automatically reconnect in reading writing...
