First of all, thank you very much for this fantastic product, Proxmox.
Everything is running smoothly for me except for one thing that I don't know how to fix.
The problem is as follows:
I have installed openmediavault 8 in a Debian VM. This is running normally without any problems. I regularly back up the data to an external USB hard drive. This is recognized, mounted, backed up, etc. as normal.
Then I unmount the hard drive, which also works as normal.
When I then disconnect the hard drive from the USB port, the VM simply stops and I have to start it manually again.
In the VM, I find the following entry in the syslog:
After that, there are only entries from booting later.
I can't find any references to this problem in Proxmox either:
After that, there are no entries except for other VMs.
The problem does not always appear on each disconnect. From 10 disconnects, it happens 3 time. And it also happens with different USB hdds (I change them weekly by rotating the hdds).
Does anyone know of a way to get closer to solving this problem?
