Default filesystem type for RAID array in DIGITS DevBox

Hi, I’m using DIGITS DevBox ( https://developer.nvidia.com/devbox ) and unfortunately failed to upgrade to Ubuntu 16 recently. Thus I’m trying to recover it by installing older and supported Ubuntu 14.

Installation has been succeeded but I see error when trying to mount raid arrays. The error says that wrong file system type is chosen. So what file system is used for the raid array in initial shipping by default ?

TIA.

I didn’t notice bcache is used for /raid. Huge thanks!
