VM SSD passthrough error

Featured Replies

Hi all,

 

I have a 250GB SSD that I want passed through to my main 'gaming' VM as I'm feeling a bit of lag and slow speeds when using a vdisk on the cache drive. I looked at the thread here: https://lime-technology.com/forum/index.php?topic=48340.0 and attempted to add the entire hdd to the VM but I get the following error message:

 

Not a valid block device location '/dev/disk/by-id/Samsung_SSD_850_EVO_250GB_S21PNXAG664859P'

 

I'm specifying '/dev/disk/by-id/Samsung_SSD_850_EVO_250GB_S21PNXAG664859P' when creating a fresh VM under the Primary Vdisk location (Setting it to manual).

 

Any ideas what would be causing this error?

 

Thanks!

 

This is what my pass-through command looks like

/dev/disk/by-id/ata-Crucial_CT525MX300SSD1_163313AAD0A9

 

Also edit your VM templet and make sure your Primary vDisk bus is set to SATA

Thank you! Fresh pair of eyes really helped. Added the missing -ata and now all working.

Does passing the device to the VM like this allow SSD TRIM to be performed from the guest?

The guest sees the disk as a physical drive so it passes everything to it.

Moved my 2 6TB Purple Drives from my physical Blue Iris server in a Windows 10 Software spanned disk into my unRaid box. Followed this to the T. Showed up in the VM was even able to import the foreign raid. Didn't even lose my archive video footage. BRILLIANT!! Thanks for this post.

Can you passthrough a SATA disk connected to MB through sata-to-usb adapter? what would the above command look like then? cheers

From wast screen shot is see that this drive is mounted... and it is formatted with btrfs. So are you trying to passthru already mounted device and possible part of the array?

To attach drive to vm it has to be unassigned  and not used by unraid for anything.

It is unassigned. I already convert vdisk.img to physic disk:
