No, I have it mounted for over a year.

Manage to fix it.

first remove the plugin and the mount is gone.

install the remote mount after works.

The problem remains.

The drive dont show in the remote mount plugin but is still there.

Using the findmnt

Code

├─/srv/5a85c508-d37e-4cca-a955-405888a77fd5                  systemd-1                autofs     rw,relatime,fd=56,pgrp=1,timeout=10,minproto=5,maxproto=5,direct,pipe_ino=16996

I cant umount , manually

sudo umount --force /srv/5a85c508-d37e-4cca-a955-405888a77fd5

umount: /srv/5a85c508-d37e-4cca-a955-405888a77fd5: target is busy.

I m using docker and a container points to this drive.
