Hi all, Recently I met a problem when using orangfs-2.9. It is fine when I run IOR (an I/O benchmarl) on local node with MPIIO and POSIX-I/O. But when I run IOR on multiple node with specified hostfile, MPI-IO is also fine but POSIX I/O will cause a error as below: ===================== ERROR in aiori-POSIX.c (line 105): cannot open file. ERROR: No such device ===================== It seems when using POSIX-IO the code line 105 ( *fd=open64(testFileName, fd_oflag, 0664); ) will alway return invalid *fd which is negative. Did anyone meet this before? Is it a bug? Btw my OS is ubuntu-14.04.1 and the mpi is MPICH-3.2.
Thank you! Vinson
