Description Saurabh 2015-05-22 10:52:16 UTC

Description of problem:
Even though the operation like rmdir is successfully deleting the directory in consideration the gfapi.log gets updated by logs such as 
"remote operation failed: Stale file handle"

This is a spurious log, doesn't seem to be giving any meaning to any one.

Version-Release number of selected component (if applicable):
glusterfs-3.7.0-2.el6rhs.x86_64
nfs-ganesha-2.2.0-0.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. create a volume of type 6x2, start it
2. bring up nfs-ganesha, after completing the pre-requisites
3. mount the volume with vers=4 or vers=3
4. create a dir and rmdir the same dir

Actual results:
step4 is successful
but gfapi.log reports

^C


Expected results:
logs should be meaning ful, it should match the operation that it is doing, present logs give a wrong impression of the system

Comment 2 Niels de Vos 2015-06-05 12:27:31 UTC

Need to investigate if logging at Warning is suitable, maybe this should be marked as Debug instead.

Ganesha does remove first, and then stats the file-handle to update the attributes (like hard-link count). The stale file handle is expected in this case.

I am don't see the ESTALE logs with the similar test
