3.1.2 Matrix Server Administration Guide

Chapter 1: Introduction 6

PanPulse daemon. Selects and monitors the network to be used for the

administrative network, verifies that all hosts in the matrix can

communicate with each other, and detects any communication problems.

mxinit daemon. Starts or stops Matrix Server and monitors Matrix Server

processes.

mxlogd daemon. Manages global error and event messages. The

messages are written to the /var/log/polyserve/matrix.log file on each server.

mxlog module. Allows Matrix Server kernel modules to send messages

to the mxlogd daemon.

grpcommd daemon. Manages Matrix Server group communications

across the matrix.

pswebsvr daemon. The embedded web server daemon used by the

Management Console and the mx utility.

mxeventd service. The distributed event subscription and notification

service.

mxregd daemon. Manages the MxFS-Linux configuration.

mxperfd daemon. Gathers performance data from files in the /proc

filesystem for use by various system components.

Shared SAN Devices

Before a SAN disk can be used, you will need to import it into the matrix.

This step gives Matrix Server complete and exclusive control over access

to the disk. During the import, the disk is given a unique global device

name. The servers in the matrix use this name when they need to access

the disk.

PSFS Filesystems

PSFS filesystems can be created on either basic volumes or dynamic

volumes. A basic volume is a single disk, disk partition, or LUN imported

into the matrix. Dynamic volumes consist of one or more imported disks,

disk partitions, or LUNs and are created by the Matrix Server Volume

Manager.
