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


glusterfs-server-3.8.1-0.4.git56fcf39.el7rhgs.x86_64
nfs-ganesha-gluster-2.4-0.dev.26.el7rhgs.x86_64
pacemaker-libs-1.1.13-10.el7.x86_64
pcs-0.9.143-15.el7.x86_64


How reproducible:
-----------------

2/2

Steps to Reproduce:
-------------------

1. Run smallfile creates : python /small-files/smallfile/smallfile_cli.py --operation create --threads 8  --file-size 64 --files 10000 --top /gluster-mount --host-set "`echo $CLIENT | tr ' ' ','`"
 
2. Run smallfile ls : python /small-files/smallfile/smallfile_cli.py --operation ls-l--threads 8  --file-size 64 --files 10000 --top /gluster-mount --host-set "`echo $CLIENT | tr ' ' ','`"

3. Try ls -R manually as well from mount point.

Actual results:
--------------

"stale File Handle" on a couple of files/dirs :

ls: cannot open directory ./file_srcdir/gqac006.sbu.lab.eng.bos.redhat.com/thrd_00/d_004/d_004: Stale file handle

</snip>

Expected results:

Comment 5 Niels de Vos 2016-09-12 05:39:48 UTC

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

Comment 6 Niels de Vos 2017-11-07 10:40:08 UTC

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.
