Running Windows Hyper-V Server 2012 core on two machines. Attempting for the first time to backup one VM from each Hyper-V Server to the other.
HV1 has a 1.5 Tb fixed VHDX that was approximately 1/4 used. I initially attempted to start replication from HV1 to HV2 across the WAN, but realized that was going to take too long. So I put HV1 and HV2 on the same LAN and restarted replication.
I also tried to replicate from HV2 to HV1 a 4 Tb fixed VHDX. There was about 1.5 Tb used of the 4 Tb VHDX.
The VMs on both Hyper-V Servers have been shut down. The files look like they copied from one Hyper-V Server to the other, but my HV1 has been showing "Merge in Progress" for over a week. HV2 seems to have completed whatever it needed
to do within 1-2 days. There is an AVHDX file on HV1, but it is not obvious to me that is changing in size at all (either growing larger or smaller - as I assume should occur as part of the merge).
On HV1 the status shows "Merge in Progress" with several periods, which cycle between 1 and 5, but there is no other progress indicator. I was expecting something to say X% completed? It looks like something is going on. The HDD
indicator is on and I can hear a lot of disk activity on HV1.
I have tried rebooting HV1 twice to see if something was stuck, but that didn't seem to make any difference. Shortly after the reboot both VMs on HV1 were back to "Merge in Progress" status.
When I look at the DIR output on either Hyper-V Server I see some slight changes in the amount of the HDD used, but not nearly as much as I would think given the amount of disk activity.
Given both Hyper-V Servers are on the same LAN right now my intention was to wait for the merge to complete before returning HV1 to its home and restarting replication across the WAN.
But this has been running for over a week. Copying the whole VHDX shouldn't take more than a few hours, so I don't understand why a merge is taking so long.
Any ideas as to why this doesn't seem to be making any progress?
P.S. Both Hyper-V Servers have a RAID hardware controller. HV1 is running RAID5. HV2 has a better controller and is running RAID6.
