Gluster is a scalable network filesystem. High-Availability for Gluster Volumes When using the native Gluster client from a Linux server there are no additional steps required to make a volume highly-available as it will communicate with the server nodes to get the updated peer status information. Red Hat Gluster Storage Architecture At the core of the Red Hat Gluster Storage design is a completely new method of architecting storage. Provides a unified global namespace that clusters disk and memory resources into a single pool that ensures load balanced I/O. High availability is achieved here by distributing the data across the multiple volumes/nodes. GlusterFS is a distributed file system defined to be used in user space For your data center Linux servers, GlusterFS might well be the file system you need for on-premises storage. There is a way using haproxy and keepalived to use a virtual ip. Using glusterfs, the ip doesn't need to change because gluster uses bricks and syncs on its own based on the configuration of the bricks... so the ip address never actually needs to change. If this cannot be done through DNS, you should edit the /etc/hosts file so that it looks as follows on all three systems: (It is also possible to use IP addresses instead of hostnames in the following setup. Overview. The most robust architecture is a three-way replica. We can see here the fault tolerance of the system as we can still work on our data storage share when server1 is offline. Client machines/users can access the storage as like local storage. GlusterFS is a clustered file system designed to increase the speed, redundancy, and availability of network storage. Install GlusterFS Server. And with that said, let's get GlusterFS up and running. Get your subscription here. However, if you reboot a client host and the brick that you've set it to initially connect to (in /etc/fstab) is down than the client won't connect at all, until you point it to another brick to bootstrap it. Distributed Glusterfs Volume - This is the type of volume which is created by default if no volume type is specified.Here, files are distributed across various bricks in the volume. In this step, we will install the glusterfs server on 'gfs01' and 'gfs02' servers. … : Now take a look at the /data directory on server1.example.com again, and you should see that the changes have been replicated to that node: Over 20 years experience as Software Developer and Linux System Administrator.
