How reproducible:
Always

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create a file on a tiered that is large enough to ensure that the file takes some time to be migrated.
2. While the file is being promoted/demoted, write some data to the file from a FUSE mount point.
3. Check that the data written in step 2 is present once the promotion/demotion is complete

Actual results:
The data written to the file is missing

Expected results:
The data written to the file should be present.
