1. Background

GlusterFS is an open source distributed file system with powerful scale-out capabilities that can support several PB storage capacity and handle thousands of clients. GlusterFS gathers physically distributed storage resources together with TCP/IP or InfiniBand RDMA, a "converted cable" technology that supports multiple concurrent links, and uses a single global namespace to manage data. GlusterFS is based on a stackable user space design that provides excellent performance for a wide variety of data loads.

GlusterFS supports standard clients that run standard applications on any standard IP network

two。 advantage

* Linear scale-out and high performance

* High availability

* Global uniform namespace

* Elastic hashing algorithm and elastic volume management

* based on standard protocol

* full software implementation (Software Only)

* user space implementation (User Space)

* Modular Stack Architecture (Modular Stackable Architecture)

* Storage of raw data format (Data Stored in Native Formats)

* metadata-free service design (No Metadata with the Elastic Hash Algorithm)

* Boot Volume

[root@server_1 ~] # gluster volume start test-volumevolume start: test-volume: success

7. Create replication volumes [compare Raid 1]

* server_1 and server_2 create a data storage directory

[root@server_1 ~] # mkdir-p / data/ exp3 [root @ server_2 ~] # mkdir-p / data/exp4

* use the command to create a replication volume named repl-volume

[root@server_1 ~] # gluster volume create repl-volume replica 2 transport tcp 192.168.60.201:/data/exp3 192.168.60.202:/data/exp4 forcevolume create: repl-volume: success: please start the volume to access data
