Expanding volume on VMware


Recommended Posts


I'm running DSM 5.2-5644

When I build my xpenology vm years ago I allocated a single 2TB vmdk to the VM for my "volume1" volume.

When setting up with only 1 disk, DSM sets the Raid type to BASIC in the disk group.   It looks like a BASIC raid type is not expandable. 

I need to expand my volume1 but looks like I'm stuck.  I should have created 2x1TB vmdk's and setup as JBOD which is expandable. 


Anyone know how I can preserve all the data in my volume1 and expand?

This post is the closest I've found to solving the problem but I'm apprehensive to do anything without checking here first since I'm on vmware.


I have about 8TB of space available in my ESX datastore so I can easily copy my original VMDK, snapshot, etc to mitigate risk.


Appreciate any feedback.  Thanks
