[gentoo-user] Re: [gentoo-cluster] Iozone on multiple nodes using ssh

[Chuanwen Wu]

 exactly, he's doing something wrong, probably has the binaries in the
 wrong place, the clientlist he's using has 1 host too
Binaries? You mean the path of iozone?
I am very sure the path of iozone is correct, and if the path is
incorrect, I can see the error message:

d...@node73 ~ $ iozone -R -s 64k -t 1 -+m clientlist
   [...]
Throughput test with 1 process
Each process writes a 64 Kbyte file in 4 Kbyte records
bash: /tmp/iozone: No such file or directory


I alsa tried to use two host in clientlist, but the result is the same.

I know what you mean. 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.
