qui-devices can become stale

[jpouellet]

Qubes OS version:

r4.0.2-rc1 / qubes-desktop-linux-manager-4.0.20-1.fc25.noarch

Affected component(s) or functionality:

qui-devices tray (qubes-manager)

Steps to reproduce the behavior:

1. Start a DispVM
2. Attach one or more devices
3. Somehow terminate the DispVM (either shutdown or killing)
4. Repeat

Expected or desired behavior:

The devices tray to show the same information as qvm-block

Actual behavior:

General notes:

I noticed this in a DispVM which probed an LVM pool with many (several hundred) devices.

I have consulted the following relevant documentation:

• https://www.qubes-os.org/doc/block-devices/
• https://www.qubes-os.org/doc/usb-devices/
• https://www.qubes-os.org/doc/device-handling/

I am aware of the following related, non-duplicate issues:

Seemingly similar state-desynchronization issues:

• Devices Widget: can't detach USB device #3525
• Device widget not showing attached devices.  #4878
• Device widget icons for block attached device inexplicably showing plus instead of eject icon (current-testing). #4849

are you using the current-testing repo? ( https://www.qubes-os.org/doc/software-update-dom0/#testing-repositories )

[marmarta]

it should have been fixed in QubesOS/qubes-desktop-linux-manager@2056e1a and looks like it works on my side; if you still experience this issue while using current-testing repository, please reopen this issue.
