Description Pranith Kumar K 2019-09-04 09:15:43 UTC

Description of problem:
When update-size-version fails on a file, application may not know that the file is in bad state even when it does fsync.

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


How reproducible:
Not easy to reproduce. An unaligned write operation should succeed partially and at the time of update-size-version all the bricks should be down. When the next write happens on that stripe it can lead to bad read-modify-write.

Steps to Reproduce:
1.
2.
3.

Actual results:


Expected results:
