Mount --bind /home/user

qn00r3 · May 31, 2024, 5:36am

Hello, I use external SSD as home directory:

user@qube:/$ sudo mount --bind /media/user/JD72YEBV106YEBS/user /home/user

Before shutting down the virtual machine, I unmount the directory:

user@qube:/$ sudo umount /home/user
umount: /home/user: target is busy.

Let me add some information:


user@qube:/$ fuser -vm /home/user

Question: Is there a way to successfully unmount a directory?
I would appreciate any advice or suggestions. Thank you.

Hi

Ideally, you should let the system handle the un-mounting during the shutdown process, wheter it’s in a qube or in dom0.

qn00r3 · May 31, 2024, 9:23am

Yes, I understand. Any ideas on how to make this happen forcibly?

solene · May 31, 2024, 11:21am

You would have to kill all processes of the user user, this requires to log into the qube as root.

unman · May 31, 2024, 12:46pm

You cant do this by logging in using qvm-run -u root, which you may be
used to.
You will have to use qvm-console-dispvm to login, then pkill -u user
should kill all processes, (and probably leave your qube in an unstable
state).

I never presume to speak for the Qubes team.
When I comment in the Forum I speak for myself.

qn00r3 · May 31, 2024, 4:51pm

I tried to do pkill -u user, the virtual machine becomes unstable.
The point of mounting the user directory on the USB Device is to avoid leaving traces in some virtual machines.
It is not possible to use disposable items in this case, because some applications leave logs that are needed later, for example, the history of correspondence.
The only option I see is to mount not the entire /home/user directory, but only some directories to which certain applications write logs, for example:

~/.var/app
~/.local/share/flatpak
~/.electrum

Perhaps someone can recommend an alternative option knowing the essence of my task ?

solene · May 31, 2024, 5:08pm

What I don’t understand is why you want to manually unmount the USB device before stopping the qube, instead of letting the qube shutdown sequence do it correctly for you.

qn00r3 · May 31, 2024, 7:20pm

Before shutting down the virtual machine, I need to do three things:

Unmount the home directory: umount /home/user
Unmount all VeraCrypt volumes: veracrypt --text --dismount
Disconnect USB from the virtual machine (I don’t know how to do this at the moment): umount USB Device from qube

I am creating a service (Systemd Unit) that runs a script to perform all three steps before shutting down the virtual machine:

[Unit]
Description=Before System Reboot or Poweroff
After=qubes-qrexec-agent.service

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/true
ExecStop=/rw/config/reboot-poweroff-script
Restart=on-failure
RestartSec=13s

[Install]
WantedBy=multi-user.target reboot.target poweroff.target

But the problem is that how can all three points be executed if an error occurs when manually starting the first point:
umount: /home/user: target is busy.

Or am I missing something and these are different things? I mean, I will introduce manual unmounting and by means of Systemd Unit.
