Im running proxmox(Linux 6.5.13-6-pve) on a T8 Firebat Plus N100 Mini PC, I am currently having an issue with using qbitorrent to download files to my SSD(setup in a VG and added as a mountpoint in a LXC) which is connected via USB to Sata w/o power, after a certain amount of download usually around 50gb the disk the VG becomes completely unresponsive on the GUI and vgs refuses to run through the CLI. unplugging the drive and plugging it back in resetting the lxc and rescanning the vg picks it back up and it then continues to fail after a couple of minutes, ive tried a couple of different SSDs and a couple of USB to sata cables with the same issue each time, the error that comes up on journactl usually relates to I/O error followed by
"reset SuperSpeed USB device number 2 using xhci_hcd"
steps taken to fix
Swapped to different USB to Sata cable - ASM1153E currently
Tried plugging in via USB 2 cable - same error
Added: quirks --
sb 2-2: UAS is ignored for this device, using usb-storage instead
usb-storage 2-2:1.0: Quirks match for vid 174c pid 55aa: c00000
disabled- uas
Tried with a powered hub 3hub

attached the output of dmesg | grep -i usb
attached journactl of everything to do with usb disconnections

I guess you know that USB connected drives can be temperamental in ANY server system, that's why they are not recommended.

You might be better off setting up the USB drive as a networked share and then bind mounting the share into the LXC, that way the LXC doesn't have to deal with any dropouts or errors due to the USB interface / connected drive.

I setup a similar system with an OMV VM managing my 4 USB drives and sharing them on the network, then the qbittorrent (or any other app) never has a problem writing, the only time I get errors is with a drive which I know is temperamental (it was removed from a NAS for showing the same errors).
