<div>Hi ,</div><div><br></div><div>Im running gluster 3.1.4 .</div><div><br></div><div>[glusterfs 3.1.4 built on May 5 2011 06:52:24</div><div>Repository revision: v3.1.4]</div><div><br></div><div>Assumed test scenario: [Might not be correct but the test python script gives a definite repro]</div>
<div> 1. create few files , write few thousands of lines of data in these files.</div>
<div> 2. now create another file in the same dir and Rename or move the new file with the old file name.</div><div> 3. Try these for few number of files.</div><div> 4 After few iterations opening these files with any application will give "Permission denied."</div>
<div><br></div><div>In my test i was using python apis - os.rename and file open apis.</div><div>This is very easy to reproduce with the attached python script </div>
<div><br></div><div><b>Note</b>: before running the script create the required directories mentioned in the script as well as create each input directories with atleast 1500 files.</div><div><br></div><div>The issue seems to be related to DHT. When I delete the link files with sticky bit ------T from the backend after the application returns "permission denied", the file becomes accessible.</div>
