USB disk files directory disappears.

RouterOS Beginner Basics
1

Hi, I have a problem with my USB disk. After some uptime of Mikrotik, all directories from the USB disk disappear.
I have connected two USB devices:

  • Huawei E3276s-150
  • Samsung T7

They are connected via Unitek Y-3089 USB 3.0 hub powered by an additional power supply (5V, 2.5A):

Below are some details:

/system/routerboard print

serial-number: **ELIDED**
firmware-type: 70x0
factory-firmware: 7.5
current-firmware: 7.5
upgrade-firmware: 7.10.2

Disks when the files directory is empty (usb1 is a Huawei LTE stick, usb3 Samsung T7 disk):

After reboot everything comes back to normal for a while:

As you may have noticed, I have several containers that like to explode when they lose access to usb3.

I will be grateful for any help.

any solution?

I have the same problem. After 24-72 hours of working fine, the USB flash device just disappears. There are no error logs, or, for that matter, no logs at all. The only indication of the problem is that the container that was running off that USB drive no longer works.
I reboot the device, and the USB stick is there again, and works as if nothing happened. Until it disappears, again. I’ve tried with different USB sticks, and they all eventually got disconnected.

Any suggestions how to debug the issue? Is there a way to get to the linux kernel logs? That may give a clue regarding what’s going on. Right now I don’t even know what’s to blame – is that the issue with the USB stick? If so, what kind of issue? Does my RB5009 have an issue with its USB port?

Maybe after a while, the power supply stops, and you need to adjust some power-saving settings?

Check usb part what is being listed there as devices.
Does USB reset bring back the stick ?

If this persists, best to create supout.rif when it disappears again and create ticket with support.

You can also try another USB stick first. Not all brands are equal.

Do you have any issues with storage without USB hub in the way? I’ve got a single device connected to my RB5009’s USB port (ADATA UR340 32GB flash drive) and so far it’s rock stable. IMHO either RouterOS doesn’t like your particular drive for some reason or doesn’t like hub you’re using.
