I think the files are differing in size because of the sparse file healing issue. Could you raise a bug with steps to re-create this issue where after healing size of the file is increasing?

| Roman,
|      The file went into split-brain. I think we should do these tests
| with 3.5.2. Where monitoring the heals is easier. Let me also come up
| with a document about how to do this testing you are trying to do.
|
| Humble/Niels,
|      Do we have debs available for 3.5.2? In 3.5.1 there was packaging
| issue where /usr/bin/glfsheal is not packaged along with the deb. I
| think that should be fixed now as well?
|
Pranith,

The 3.5.2 packages for debian is not available yet. We are co-ordinating internally to get it processed.
I will update the list once its available.
