No, that is just not the case. I just wanted to be sure of the
implications of what I was doing and what areas of the operation of
Samba and CTDB might be affected given the confusing results of my
ping_pong tests.

I did not "put it" like anything. I just saw an problem in my setup,
read some documents on the samba wiki, followed some advice and saw some
unexpected behaviour. Perhaps I imagined the wiki to be more moderated
that it really is, so my trust was misplaced. I don't blame anyone, all
I'm trying to do is solve a problem.

AFAIK I don't need to get it to work with mmap, just get MooseFS to fix
the non-mmap I/O coherence as, as Volker says, mmap is only important
for TDB files and we don't store those on MooseFS.

Again, no "blame" was ever implied. I saw Winbindd using 100% CPU after
changing the "use mmap" parameter to "no" and was rather perplexed as to
how that could happen. The first natural place to ask would be this
list, no? I also don't recall using any accusatory or inflammatory
language, just stating observations, posting logs and actually at one or
two points saying I'm also talking to the MooesFS devs.

As a busy sysadmin I rely on a number of sources to design and set up
infrastructure, and sometimes it's easy to get mislead. At no point have
I ever questioned the knowledge of people like Jeremy, Tridge, or
Volker. I'm just dismayed as a professional at getting "ROFLS" in a
reply to what I feel are perfectly sensible questions stemming from a
misguided source of documentation.

Apologies for clutter.
