Exchange DAG fails because of sector size does not match

Hi,

My dag on exchange 2010 sp3 fails because

"The log copier was unable to continue processing for database 'mb03-data01\TITAN-EX-A-MB03' because an error occured on the target server: Continuous replication - block mode has been terminated. Error: the log file sector size does not match the current volume's sector size (-546) [HResult: 0x80131500]. The copier will automatically retry after a short delay."

I got two servers running windows 2008 R2 on hyper-v 3.

The VHD files on the servers are dynamic .vhdx disks.

If i look with "fsutil fsinfo ntfsinfo" on the disks for the loggfiles i got different result, on the "sending" DAG member i got
Bytes Per Sector  :               512
Bytes Per Physical Sector :       <Not Supported>
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024

And on the reciving
Bytes Per Sector  :               512
Bytes Per Physical Sector :       4096
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024


Does anyone know what is causing this differance or a workaround for it?

Hello, thanks for your assisting help! It was the storage drivers that had to be updated on the servers, i ran the VM integration disk and upgraded the drivers and now it works :)
Your help has saved me hundreds of hours of internet surfing.
