VM Windows Server2 008 R2 with a 3TB USB-Harddisk not working

[dope76]

Hi,

i have installed a Windows 2008 Server R2 VM.
Now i want connect a 3 TB USB-Harddisk. After the passthru with USB in the config file (usb0: host=****:****) is too slow but works, i decide to connect as a "real" Harddisk with "virtio1: /dev/sd*".

The problem is after i boot the VM and initialize the Harddisk the VM turns off. I see the Harddisk in theDisk Management utility. There is also no matter if mbr or gpt or one partition or more .

is there any other option i overlooked?

My Configfile:

virito0: harddisk:102/vm-102-disk-1.raw,format=raw,size=50G
virtio2: /dev/sdd (internal harddisk 3 TB no Problem)
virtio3: /dev/sde (external harddisk 2 TB no Problem)
virtio1: /dev/sdf (external harddisk 3 TB PROBLEM)

Thanks for your Answers

The USB drive is going to sleep, that is why you are not able to access it after a reboot.

I have the same problem and have yet to find a solution.

Hi,

i can access it after a reboot, but only with the entry:
usb0: host=****:****
and this option is very very very slow.

with the entry:

virito1: /dev/sdf
the VM (Windows Server 2008 R2, Windows 7, FreeNAS) crash.
with my other harddrive the VM have no problems

Are you sure that it is plugged into the USB 2.0 and not USB 1.1 port? That may explain the speed issues.

Hi,
i'm sure that the harddisc is plugged into the USB 2.0 port. i a nother forum they write passthrou in proxmox is only USB 1.1.
