Hi Michael, Thank you very much for you useful suggestion. I did meet some problems when I build the kmod with kernel version 2.6.35.11. Some mistake occurred saying the member of task_struct not found. I search the source code using 'grep' to find the members were not useful actually. So I deleted them and the kernel module could be compiled. I missed other warning too. May some of them do matter much. ================================= #!/bin/bash sed -i /strategy/d src/kernel/linux-2.6/pvfs2-proc.c -sed -i /ctl_name/d src/kernel/linux-2.6/pvfs2-proc.c =================================
I tried the latest OrangeFS version, 2.8.4 today. Fortunately, it worked as I expected. I can now run pvfs2-ping/pvfs2-ls/pvfs2-cp successfully as well as mount command. The mounted directory can also be accessed via POSIX style, say, ls/cp/touch etc. I will try to run MPI programs using PVFS2 as the shared-disk parallel file system. Since my purpose to set up PVFS is to do some related research, I will report more to you guys if you're interested in the performance of PVFS on Amazon EC2 cloud platform. Many thanks.
