Subject: buffer cache question
Date: Sun, 18 Dec 2005 22:09:01 +0100	[thread overview]
Message-ID: <000001c6047c$a2458a40$0400a8c0@dcccs> (raw)

Hello, list,

I use 4 disk nodes with NBD.
All of my nodes have 2GB ram.

But the buffer cache newer rise over 830MB.

Is there some limit?
Where can i change this limit? (if it is)

Thanks,
Janos
