[Ocfs2-devel] kernel bug

[Changwei Ge]

Hi BASSAGET,

We ocfs2 developers are solving a DIO crash issue which may share the same root cause with yours.

You can refer to my patch set of 2 and backport them into your kernel to see if the issue can be kicked away.

  ocfs2: make metadata estimation accurate and clear
  ocfs2: try to reuse extent block in dealloc without meta_alloc
