About to migrate to UnRAID - can I split an SSD?

[LemonLuddite]

Hi Folks,

 

From some googling I think this isn't possible but it'll impact how I architect things.

 

Unraid booting from USB

Pool of spinning rust

SSD partitioned in half, one passed through to a windows VM the other mounted in Unraid for a plex metadata store

 

If I can't then moving Plex from Unraid into the Windows guest will work but is probably slightly less performant. 

 

Cheers,

Lemon.

Correction of terminology: "array" of spinning rust.

Pool can refer to the cache pool so using pool interchangeably can be confusing.

 

SSD does not need to be partitioned like that. Just put the SSD in the cache pool and put a vdisk for the Windows VM and the plex db (and docker image) on the cache pool. It essentially achieves the same thing (just set the vdisk to be half the size of the SSD if you want to use up to half the SSD for the Windows VM). The pro of using vdisk is that it is thinly provisioned.

 

You can mount the SSD as unassigned device (there's a plugin for that), format it with 2 partitions (warning: command line) and set things up manually (warning: manually!) and achieve what you are after. However, the performance benefits you will get (or not get) is minute compared to the complexity.

Excelllllent. That's pretty much everything squared away so. Just waiting for a new disk shelf and I can start the long task of migrating all the data. 
 

Cheers for your help.
