Description Csaba Henk 2017-11-10 19:21:43 UTC

+++ This bug was initially created as a clone of Bug #1364740 +++

Description of problem:
- window-size option does not work when it is > 128KB
- trickling-writes is not configurable


Version-Release number of selected component (if applicable): 3.8


How reproducible: Always


Steps to Reproduce:
1. Write a 1MB file to a gluster mount and observe write sizes on the bricks.

Actual results: Write sizes are always buffered into 'page-size' (128KB) chunks rather than 'window-size' chunks.

Expected results: We expect the window-size to be respected and the writes buffered accordingly.

This bug is automatically being proposed for the current z-stream release of Red Hat Gluster Storage 3 by setting the release flag 'rhgs‑3.1.z' to '?'. 

If this bug should be proposed for a different release, please manually change the proposed release flag.

All 3.8.x bugs are now reported against version 3.8 (without .x). For more information, see http://www.gluster.org/pipermail/gluster-devel/2016-September/050859.html

--- Additional comment from Niels de Vos on 2017-11-07 05:37:11 EST ---

This bug is getting closed because the 3.8 version is marked End-Of-Life. There will be no further updates to this version. Please open a new bug against a version that still receives bugfixes if you are still facing this issue in a more current release.

The situation described in the original, EOL'd bug, Bug #1364740, still prevails, so we are cloning it for mainline.
