Should have mentioned: pvfs 2.8.2 Ubuntu 10.04, kernel 2.6.32-25-server, using kernel module
Using two patches from Kevin Harms regarding Berkeley DB and multiple filesystem entries in /etc/pvfs2-fs.conf (I believe these have since been committed to HEAD).

All- I'm having a problem where files written to a PVFS volume overwrite the beginning of the file after some output has already been generated, as if lseek() had been called mid-write. The overwriting behavior does not show up on a regular ext3 volume. Sample code is attached. I'd like to know if anyone can duplicate this behavior, because it looks like a bug. Essentially what happens is this: given a large (1024+ character) string, I write some portion of the string using a C++ ostream, then write another line: out << st.substr(0, N); out << "done"; If N < 1024, everything is fine. If N >= 1024, "done" is written at the beginning of the file, overwriting what was there before. I'd love to figure this out!
