Hey folks,
I used for a long time 4.2.1, 4.2.2, 4.2.3 but after these I used for a few months Ubuntu. Well… Ubuntu is not a solution for what I need so I came back to Qubes, 4.2.4 this time.
I have a problem though. I want to put some of my backup on an AppVM called Vault but I have problems in attaching the external SSD. The manifestation was different but now I got only 1 error.
I am using the top-right icon ti attach/detach devices (I have separate sys-usb).
- First manifestation was to actually not attaching anything even though the device was looking attached to the desired AppVM.
- Second manifestation now is that I get a notification saying:
error: qubesException - Device attach failed: Failed to add inotify watch for /run/udev: No space left on device.
Below are the lines from logs that appear after I try to attach the device.

How do you attach external thumb drives? Now I see that in the USB icon (top-right) the storage devices appear on another section called “Data (Block)) Devices”. Where shall I try to add the device, from this section or the below section?
