Ocfs2 devel - Mar 2015 - some problem encountered when running ocfs2-test

Hello ocfs2 developers,

I and Zhen are new for ocfs2 project, we are looking at ocfs2-test testing suits
for evaluating the ocfs2/ocfs2-tools quality, now there are some problem
encountered when running ocfs2-test.
1) How to evaluate ocfs2/ocfs2-tools after you add some new code? only use
ocfs2-test? but it has been inactive for 2 years. I just want to know if there
is any other test suits, hope some old people can give some suggestions.
2) We set up a ocfs2 cluster under openSuSe 13.2, tried to run ocfs2-test-1.0.4
test suits, but two cases cannot pass, just want to know who encounter the
similar problem and how to fix.
2.1) run_mmaptruncate, run this case in the condition "blocksize=4096
clustersize=1048576 sparse,unwritten,inline-data  data=writeback" will be
hanged.
2.2) run_reflink_test, run to this step "[11] OracleVM Data Integrity
Test", this will last lots of time and then let this VM node reboot, this
test case cannot be completed.


Thanks
Gang
