Hi Coly,

How did you setup the env for testing? are you using the latest
testsuite from ocfs2-test.git? As for the cluster testing, we need to
install openmpi first, and setup passwordless ssh&rsh connection among
all nodes.

Besides, all testing binaries need to be run from a installed BINDIR
after a successful building&installation.

Tristan
