X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 25 Oct 2006 12:03:58 -0000 Hi, vmstat reports that quite a few processes are waiting for io (disk access) so I ran gstat to see how much the drive is working and it says more or less 100% constantly. How can I determine which process (if it's mostly one single process) is using the disk so much? top says the CPU is mostly idle. Thanks, -Patrik
