Hyper-V Server Replication Question

[abillybob]

Hello All

 

Hoping you can help.

 

So we have two Hyper-V Servers some servers are hosted on one and other servers are hosted on another. But they replicate between each other for redundancy. Recently our Hyper-V A Server crashed for no known reason... event viewer won't tell me anything. So I started the Virtual Server running on it to run on Hyper-V B instead as a temporary measure. I couldn't take it down at this point so had to leave it on and as it's a terminal server people where working on it throughout the day. I then obviously wanted to replicate back to the old Hyper-V A server so that work wouldn't be lost but when I selected reverse replication it wanted to backup nearly 2TB of data which in turn we have now lost all space from the physical hard drive on Hyper-V A. I just presumed this would only sync over the changed files back to Hyper-V A not the whole server again.

 

So now I'm stuck and I'm confused where to go from here, I need to somehow remove all the backup files to create the room back on Hyper-V A and then find another way to copy over the changes and start it up on the Hyper-V A server?

 

Any ideas on how to go about this, I've been lucky in the past and haven't had a Hyper-V server have a problem before so haven't dealt with this before now!

 

Thanks

Alex

The replica server wouldn't know what data has changed in an unplanned failover.

You might have to either manually remove the data from the primary but that sounds really dodgy. Or try to make Hyper-V B the primary host for this VM then set up replication for it again, it sounds like it's primary for some other VMs already? Either way afterwards it sounds like your setup needs assessing and storage requirements analysed.
