I just gave the example, in the case the path of iozone is incorrect, what would happen, And the result is the error below will be print out: >> bash: /tmp/iozone: No such file or directory I just tried to proved that the path of iozone in my nodes is correct. > > # hostname directoryForTestFiles pathToIozoneOnEachHost > node1 /net/NAS/awesomeFS /home/somewhere/bin/iozone > node2 /net/NAS/awesomeFS /home/somewhere/bin/iozone > node3 /net/NAS/awesomeFS /home/somewhere/bin/iozone Now, I almost gave up iozone. I have tried iometer, which is better at testing parallel fs as I know. It's very easy to config and run. -- wcw
