[lustre-discuss] statfs Error while running IOR benchmark on lustre setup.

[Gadre Nayan]

Dear all,

I have installed lustre on 4 nodes, all on same network.
I want to run IOR benchmark on the setup.

I have tested the mpi ring by using the following commands:

mpd &
mpiexec -n 1 /bin/hostname
mpdallexit

output: hp01 (local machine name)
***********************************************
sudo nano mpd.hosts :- updated the clients here (2 clients hp01 hp02)
mpdboot -n 2 -f mpd.hosts
mpdtrace

output:
hp01
hp02

expected. 2 clients(hp01 hp02)

*****************************************************

mpdringtest
mpiexec -n 30 /bin/hostname

ouput: prints hostname hp01 15 times hp02 15 times:

***************************************************************














*When I run IOR on this setup using:mpirun -np 2 Gadre/IOR/src/C/IOR -f
Gadre/IOR/scripts/testScriptI get following error:IOR-2.10.3: MPI

What does your IOR script look like?
