[OpenAFS] Re: cyrus with storage in afs?

[Robert Banz]

I personally wouldn't want my mail storage on AFS.  I say that  
because, right now, it is, and I can't wait to get it off of it.   
It's caused me nothing but problems, because the AFS fileserver  
doesn't just seem to be "made" to handle the transactional intensity  
of mail-land.  We got around a lot of our performance issues by  
moving from a berkeley-based mailspool to a maildir-like one a couple  
years ago, but now are always coming up against performance (leading  
into stability) issues caused by AFS being part of the stack.  Less  
things being part of the stack with your mail system will make things  
better; run it on some quality fibre or iscsi attached storage and  
you won't end up screaming in pain later on.
