[Gluster-users] A problem with gluster 3.3.0 and Sun Grid Engine

[Pranith Kumar Karampuri]

Manhong Dai,
   Thanks for the script. Could you give the volume configuration also so that we can re-create the problem in our setups.

Pranith.

Hi Avati, 


Thanks a lot! In my case, the application that tries to create a new file is not inside the folder. 


I write a simple bash scrip to demo this problem. 

#!/bin/bash 
FOLDER=/home/mengf_lab/daimh/temp/testdir 
for ((i=0; i<100; i++)) 
do 
echo "###$i###" 
ssh mengf-n1 "rm -r $FOLDER; mkdir $FOLDER" 
seq 10 |split -l 1 - $FOLDER/a. 
done 


And its output is 
###0### 
###1### 
split: /home/mengf_lab/daimh/temp/testdir/a.aa: No such file or directory 
###2### 
split: /home/mengf_lab/daimh/temp/testdir/a.aa: No such file or directory 
###3### 
###4### 


Best, 
Manhong

Hi, 


We got a huge problem on our sun grid engine cluster with glusterfs 3.3.0. Could somebody help me? 


Based on my understanding, if a folder is removed and recreated on other client node, a program that tries to create a new file under the folder fails very often. 





Is the directory deleted and recreated by another client/mount while the application which attempts to create the file stays cd'ed inside the directory? Can you try to confirm if this is the pattern?
