VM on external USB3 device

Post by altharos » Sat Feb 03, 2018 10:19 am

Hi,
I Had a Windows 2016 image on a usb3 hard drive and i wanted to move it to a USB3.1 SSD but now virtualization station can no longer shows external devices when choosing a location for the VM.

I am using a TS-453+
firmware 4.3.4.0435 Build 20171230
Virtualization station is on version 3.1.7 (2018-01-23)

Any idea why they would remove being able to store on a USB device? and is there a way to enable it again.

Thanks

Is this still the case, that you cannot store a VM onto a USB storage device?

I'm guessing that maybe it's because of the risks associated with having critical data like that on non-redundant and external storage?

Maybe they realized that some things crash badly if that media is unintentionally disconnected?

For a more educated answer you need to ask Qnap.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!

A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.

All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

I wrote a ticket a few weeks ago to QNAP and in the end they told me that there were problems when using external drives for a VM, so they stopped it.
On my TS-453A I am using a VM on an external SSD since I bought it in May 2016 and I had no problems using it. It still works. I can not create new ones, but this one is running.

Another user of the German speaking QNAP Forum got the message from QNAP that he should make a feature request that VM on external disk should be allowed!
So please, write also a feature request to QNAP!

Has anyone found a solution for this? This has rendered my setup useless i hate having VM's run on the standard storage because they run dog slow because im using WD reds its also noisy very fustrating ive been using this for years. Cant believe they have just dropped functionality, how about warn people not to put critical VM's on volatile storage

One option if you have the slots available would be to remove the SSD drive from the USB shell and install it internally in the QNAP. That would allow you to work around that limitation.

I have figured out the solution to bypass the virtualization station's limitation about usb drive.

You just need to create a link from your usb SSD to your main pool.



Code: Select all

ln -s  /share/external/DEV3303_1 /share/Public/usbSsd


In this case, your SSD becomes a folder under Public. Then virtualization station will find that folder and run VM in it.

But because Qnap only enable UASP on its own USB expansion closure, your USB SSD cannot have UASP. The speed is limited due to that. My speed test shows about 250MB/s. It is a TS-253Be.

Also Qnap does not support TRIM on the third party USB closure. So your SSD's performance after using a while is also impacted.

When i do this it accepts the command, and creates the link but the share isnt accessible on the qnap

Once its mapped how do you move the VM, i added it via ssh and can see the link

usbSsd -> /share/external/DEV3303_1

but i cant cd into it and the qnap cant see it
