I'm trying to do noncontiguous writes on a Lustre filesystem using MPI-ROMIO routines. It is failing in ADIOI_Set_Lock with the message:
File locking failed in ADIOI_Set_lock. If the file system is NFS, you need to use NFS version 3, ensure that the lockd daemon is running on all the machines, and mount the directory with the 'noac' option (no attribute caching). Now I've searched the web for some solution but only seem to come across similar problems. Is there some way to mount a lustre filesystem so that it somehow does the right thing here and use the ufs kernel interface? NFS mounted filesystems work fine as they provide the file locking mechanism apparently.
