I've got an UnRAID host with a VM running ( two actually ), and i'm running the 6.9 Beta 25 build with it's epic multi cache disk setup. What i'd like to do is have the OS vdisk on one drive, and the photoshop scratch disk on a different drive.  Problem is Photoshop won't let me make a mapped drive the scratch disk.  So... i was thinking that maybe i could make a second vdisk, (which lives on a different ssd) and map that in the xml.  

 

Question is, can i create a blank vdisk... from the command line? Is that the best way to do this in UnRAID?  ( Very open to alternative solutions too 🙂 )

 

Oh and PS... i'd really rather not grow the primary vdisk.  I like keeping them small so the they are easy to backup. Also, i'd like to get the OS and Scratch on two separate SSD's.

Details about why i don't just grow the disk

On the VM configuration screen click on the + beside the primary vdisk to expose the 2nd vdisk settings.

Interesting.  So i was over thinking this.  I'll give that a shot, thanks.

Ok, yeah that worked like a charm.  Glad i asked, I was half way down the road to reading up on the dd command for creating these from the command line in linux.  Didn't look that hard, but it was much nicer to be able to create it from the GUI.
