Feb 12 19:47:18 ip-100-0-100-1 kernel: [2541168.023638] XFS (md0): I/O Error Detected. Shutting down filesystem

Is an IO error from MD.

I would suggest trying to reproduce without MD in the picture first - always 
best to try to reproduce with the simplest setup first and work your way up the 
complexity ladder,
