M.2 stored VM share - how to bypass parity

[tuxbass]

Hi,

finally finished my build and got the unRAID licence.

Drive layout is follwing:

 

- 3x HDD (one of which is a parity drive);

- 1x SSD for cache

- 1x M.2 (on PCIe lane) for VMs

 

Is there any way to isolate the latter from the array, or at least the parity calculation, not to bottleneck the M2 performance?

I see there is an option to bypass cache, but don't see any option for bypassing parity.

 

Would the "Included disk(s):" (and related exclusion option) work for this?

You're going to have to mount it outside the array. See Unassigned Devices plugin.

To whomever might have the same question - there's no need to have your vm stored in the array. Simply mount the drive however you please, and that'll be just fine.
