Description Sebastian Thomae 2014-04-08 14:52:37 UTC 
Description of problem:
Two Peers (one 32bit one 64) have a brick each and form a volume
When i mount this volume on a 64bit host everything works fine.
When i mount it on a 32bit host everything works fine until i add a lot of files.

When i have added a lot (several million) files in directories to this volume i cannot browse the share from the 32bit client any more.




Version-Release number of selected component (if applicable):
All Hosts have version 3.4.2 installed

How reproducible:
sometimes it needs a restart of the client (glusterd) to show this behaviour

Steps to Reproduce:
ls -al /path/to/mounted/volume

Actual results:
ls: cannot access /path/to/mounted/volume: Input/output error

Expected results:
list of files shown

Additional info:
There are several bugs with this or similar behaviour since 2009 and all but one were closed without an explanation why this happens

changed mount type
Comment 4 Sebastian Thomae 2014-04-08 15:18:58 UTC 
if i delete most of the files from a 64bit machine the volume gets accessible again
Comment 5 Sebastian Thomae 2014-04-09 06:34:00 UTC 
any directory with only a few files in it works fine while directories with many files in it show IO errors on the same Volume

Rebase of http://review.gluster.org/7278 to 3.4.2

Patch for testing against 3.4.2. The problem is related to READDIR(P) procedures and the patch contains major corrections for this.
Comment 7 Sebastian Thomae 2014-04-09 08:17:30 UTC 
this patch works for me
Comment 8 Niels de Vos 2014-04-09 11:44:11 UTC 
Marking as a duplicate of the 32-bit server and 64-bit client bug. The same patch seems to resolve this issue too. Please follow bug 1074023 for details on when a release contains the fix.
