currently running one physical server with 4 VMs on a host running hyper-v. we have 4TB total raid array of space but our main VM with 2TB is almost full and i would like to increase the space. i thought i could allocate more space to that VM or slap in more drives, create a volume, and merge. but apparently that is not doable because it is a VM using VHD? (i am still kinda new to this)

if this really is the case, can someone briefly explain why. and if so, how do i fix this and add more space with least amount of downtime while retaining the current data.
 
ah ok yeah i have read a bit more since i posted.

i am assuming this conversion will retain all the data but will require some significant downtime?

*edit*
uh, But VHDX disk format technology is not supported in Windows Server 2008 R2
 
2TB is the limit on 08 R2 without passing through a physical disk, there's a reason hyper-v pre WS2012 was generally reviled in the VM community. Unless you need specific features of full server 2008 R2 on bare metal, why not just upgrade to Hyper-V Server 2012, as it fixes the 2TB and many other issues and limitations.

Click to expand...

So I could upgrade just the host to hyper-v 2012? We have another issue i haven't mentioned. our main server is running small business server 2011 and we are rapidly approaching the 75 user limit (filled about 20 positions in 3 months) and it doesn't look like its slowing down. maybe its time to upgrade everything.

*edit*
i see 2012 hyper-v is free standalone but our host runs backup exec and couple other random tasks.
