Hi All,
I have installed IOR 2.9.0 on lustre client.
IOR is running in user mode.
I fired command "./IOR -O lustreStripeCount=10 -o test1.txt" and
output is
below:
Output:
IOR-2.9.0: MPI Coordinated Test of Parallel I/O
Run began: Fri Sep 29 20:04:42 2006
Command line used: ./IOR -O lustreStripeCount=10 -o test1.txt
Machine: Linux mds
Summary:
api = POSIX
test filename = test1.txt
access = single-shared-file
clients = 1 (1 per node)
repetitions = 1
xfersize = 262144 bytes
blocksize = 1 MiB
aggregate filesize = 1 MiB
** error **
ERROR in aiori-POSIX.c (line 94): This IOR was not compiled with Lustre
support!.
ERROR: No such file or directory
** exiting **
So please can somebody tell me steps of compilation of this IOR with Lustre
support?

Where may one obtain the source for IOR that contains the special support for Lustre ? Enjoy, Don Capps

This calls an ioctl to set the striping for a given test run. It _should_ really cal llapi_file_create(...) to set the striping, via liblustreapi.a.

I believe the latest sources are always available at: ftp://ftp.llnl.gov/pub/siop/ior/ Look in the Makefile.config for a Lustre related macro (-D_USE_LUSTRE). That said, I think CFS has changed its mind about the best way to do what you are trying to do. The macro enables the compilation of some ioctl calls for striping. It''s been a while and I don''t recall for sure, but I think you may also need to make sure of a Lustre related include file. As a simpler alternative, you might investigate setting the target directory''s default stripe count with "lstripe". That''s what I do these days.

The "lstripe" and "lfind" wrappers are removed in 1.6 - they were for compatibility with Lustre 1.0. Cheers, Andreas -- Andreas Dilger Principal Software Engineer Cluster File Systems, Inc.
IOR uses the striping ioctls to pre-stribe data files during its sets of runs, so it may not be feasible to set a directory default, as IOR can be configured to change that striping for each file. Adding the make file macro does enable this.
