User reports successfully formatting and using an ~18TB Btrfs volume on hardware raid5 using i686 kernel for over a year, and then suddenly the file system starts behaving weirdly:
http://www.mail-archive.com/[email protected]/msg31856.html I think this is due to the kernel page cache address space being 16TB limited on 32-bit kernels, as mentioned by Dave Chinner in this thread: http://oss.sgi.com/pipermail/xfs/2014-February/034588.html So it sounds like it shouldn't be possible to mount a Btrfs volume larger than 16TB on 32-bit kernels. This is consistent with ext4 and XFS which refuse to mount large file systems.
