Ji-Hyeon,

You're saying that "stripe=2 transport=rdma" should work.  Ok,
that was firstly I wanted to know.  I'll put together logs later this week. 
Thank you.

Note that "stripe" is not tested much and practically unmaintained. We
do not advise you to use it. If you have large files that you would like
to split in smaller chunks for improved distribution and faster
self-heal, you can try to enabled "sharding" instead:
