Is this a 32bit system you are using? Such systems can only support
buffered IO up to 8TB. If you use iflags=direct to avoid buffering, you
should get access to the whole device.
You found the problem, and you also found the reason why btrfs_tools
also fails past 8GB. It is indeed a 32bit distro. If I put a 64bit
kernel with the 32bit userland, there is a weird problem with a sound
driver/video driver sync, so I've stuck with 32bits.
Huh. Learn something new every day, I suppose. Never would have
thought of this. Thanks, Neil.
