I added some capacity to both virtual hard disks of the only 2012 R2 guest running on the 2012 R2 host. Disk capacity was added to the guest, and I expanded both drives on the guest. All seemed good.

Little while later I received a message that the replication was critical. The 1st event ID was 33680, which only said the replication failed. This was followed immediately by IDs 32086 and 32422.

32422 said:
Hyper-V Replica failed to apply the log file onto the VHD for virtual machine 'xxx-Svr1'. (Virtual machine ID 05EB0EC0-E24E-4F3E-9AB8-CC005C78634D). An out-of-bounds write was encountered on the Replica virtual machine. The primary server VHD might have been resized. Ensure that the disk sizes of the Primary and Replica virtual machines are the same.

Oh crap...didn't realize I had to also resize the disks on the replica, too! Sigh...

https://blogs.technet.microsoft.com/virtualization/2013/11/14/online-resize-of-virtual-disks-attached-to-replicating-virtual-machines/ said to resize the disks on the replica, then resume replication.

Did all that...to no avail!

Restarting the host and the replication servers didn't resolve the problem. Yikes!

What should I try next?

Thanks

Break and re-establish replication.  That's probably the simplest solution.

That's ultimately what I did.
