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:
address@hidden 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!
