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, Jeongsook. ---------- [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.
