Please listen to him, do what he advises and don't bother contacting Sernet, because you already have. Rowland

What am I supposed to be listening to? I'm just suggesting some way I can contribute to MooseFS by getting it to work consistently with Samba/CTDB. Volker suggests just dropping the FS which is not a very good option for our organisation right now. The wiki is unclear and contradictory, and I don't have the facts to update it without risking it being equally broken afterwards, and misleading others, so that's why I'm trying to provide clear information, performing tests, reporting back, and asking for advice to find out how it really *does* work. I feel a little offended by the tone of this message, as I've been on this list for over 15 years and feel I've helped out a lot of people with other queries I've already experienced. I am prepared to pay Volker via Sernet as this is of great importance to us and will help develop another open source product. Is that so hard to understand?

You were coming over as if you didn't want to do what you were being advised to do.> > I am prepared to pay Volker via Sernet as this is of great importance > to us and will help develop another open source product. Is that so > hard to understand? >When you put it that way, no, but the way to put it previously, yes. how should I put this? MooseFS sounds like it isn't useful with CTDB, you have paid for MooseFS, it doesn't work, so you are now blaming Samba. You need to do what Volker says and get MooseFS to work with mmap. Rowland
