[Gluster-devel] glusterfs(3.2.7) hang when making the same dir at the same time

[Song]

Hi,

 

Recently, glusterfs will hang when we do stress testing. To find the reason,
we write a test shell script.

 

We run the test shell on 5 servers at the same time. For a moment, all test
programming is hang.

When execute command “cd /xmail/gfs1/scl_test/001”, also hang.

 

The test shell script:

 

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

do 

rmdir /xmail/gfs1/scl_test/001

if [ "$?" == "0" ];

then 

echo "delete dir success"

fi 

 

mkdir /xmail/gfs1/scl_test/001

if [ "$?" == "0" ];

then 

echo "create dir success"

fi

 

echo "1111" >>/xmail/gfs1/scl_test/001/001.txt

echo "2222" >>/xmail/gfs1/scl_test/001/002.txt

echo "3333" >>/xmail/gfs1/scl_test/001/003.txt

 

rm -rf /xmail/gfs1/scl_test/001/001.txt

rm -ff /xmail/gfs1/scl_test/001/002.txt

rm -rf /xmail/gfs1/scl_test/001/003.txt

done

 

“/xmail/gfs1” is native mount point of gluster volume gfs1.

 

Gluster volume info is as below:

[root at d181 glusterfs]# gluster volume info

 

Volume Name: gfs1

Type: Distributed-Replicate

Status: Started

Number of Bricks: 30 x 3 = 90

Transport-type: tcp

 

 

Please help me, Thanks!
