A data integrity checksum error occured. Data in the file stream is corrupt

I am running Windows Server 2012, with two drives in a storage pool (mirrored). I have created a volume on top of this storage space, formatted as ReFS.

In the event logs, I am getting a ton of errors with Event ID 155, Source DataIntegrityScan with the message:

File data scrub operation filed. File name: E:\filepath; range offset 0xA20000; range length: 0xC0000 bytes; repaired: 0x0 bytes; note repaired: 0xC0000 bytes; status: A data integrity checksum error occurred. Data in the file stream is corrupt.

In Disk Manager the drives show as healthy, and when I try to scan the volume for errors I get the message:

"You don't need to check this drive The ReFS file system does not need to be checked".

Questions:

  • I thought ReFS protected against corrupted data. Why am I getting a message that my files are corrupted?
  • How can I troubleshoot/solve this problem?
