measuring disk performance with clustered IOzone

Dear all,
I don't know how I can figure this problem out.

I tried to execute iozone with clustered mode but it didn't work. It stalled after executing the last line (see below!)
What do you think the problem is?
Please let me know if you have similar experience to me.

Best regards,


[root@host current]# ./iozone -i0 -i1 -R -I -+n -w -r 128k -s 1G -+m node.lst -t 4

Run began: Mon Apr 13 17:07:21 2015

Excel chart generation enabled
O_DIRECT feature enabled
No retest option selected
Setting no_unlink
Record Size 128 KB
File size set to 1048576 KB
Network distribution mode enabled.
Command line used: ./iozone -i0 -i1 -R -I -+n -w -r 128k -s 1G -+m node. lst -t 4
Output is in Kbytes/sec
Time Resolution = 0.000001 seconds.
Processor cache size set to 1024 Kbytes.
Processor cache line size set to 32 bytes.
File stride size set to 17 * record size.
Throughput test with 8 processes
Each process writes a 1048576 Kbyte file in 128 Kbyte records
