Fails to mount Btrfs volume when sufficiently large

[Geo25rey]

I made a 1GB RAID 10, far2 array in Linux and created a Btrfs volume on the raw RAID device (md0) and that worked fine. I was able to read and write to the volume both on Windows and Linux.

Then, I did the same process, but made it 300GB and installed Black Ops 6 via Steam onto the array. Everything else was the same.

I'm not sure if this is an issue with WinMD not supporting large enough partitions (although 300GB is not that much) or if WinBtrfs is not getting triggered properly once WinMD initializes the RAID volume (maybe a race condition?).

I'll try to get a script together tomorrow to make reproducing this issue easier.
