Can you quote these docs, so that we can correct them?

Yes, it is a high worry. If MooseFS is not mmap coherent, you need
"use mmap = no", and we need to fix Samba and/or MooseFS to support

This is weird. ctdb-controlled files should have the node-number
appended. Are you sure that you are running ctdb?
