Preperation for GlusterFS

Steps to do before installing and using GlusterFS

Preparation

Before we can set up GlusterFS we need to set up the NTP protocol for the servers. Due to the file operations on distributed servers, any operation (read/write) has a time stamp. If the servers are not synchronous to each other, files can/will be distributed/replicated wrong.

Setup NTP

Make sure both servers have the same time zone and NTP is installed on both servers.

Switching to ntpd

Linux has already a time controller. However, we are making sure that the servers are using NTP.

Disable TimeDateCtl NTP

timedatectl set-ntp no

Install NTP

apt-get install ntp

Verify if everything is working.

ntpq -p
