[Gluster-devel] Create directory error

[Ben Mok]

Hi All,

I got some error when create directories. If create several directories from
client A and then delete the directories from client B. The error message
will be showed as below when the same directories are created again from
client A, and the return value is 1.  

mkdir: cannot create directory `/pgfsfs/test/a98': Device or resource busy

 

In fact, all directories can be created, just some creating got error
message and return 1. If create and delete directories from same client, it
have no problem. 

You can repeat the symptom easily by below script

 

#!/bin/bash

folder="/pgfs/test/"

for ((i=0;i<=100;i+=1)); do

mkdir $folder$1$i

echo $?

Done

 

Testing procedure:

1.       run script from client A

2.       rm -rf * from client B

3.       run script from client A again 

 

Version of clients and servers are 1.3.10
