6.3. Creating Distributed Volumes

Figure 6.1. Illustration of a Distributed Volume
Warning
Create a Distributed Volume
gluster volume create
command to create different types of volumes, and gluster volume info
command to verify successful volume creation.
Pre-requisites
- A trusted storage pool has been created, as described in Section 5.1, “Adding Servers to the Trusted Storage Pool”.
- Understand how to start and stop volumes, as described in Section 6.10, “Starting Volumes”.
- Run the
gluster volume create
command to create the distributed volume.The syntax isgluster volume create NEW-VOLNAME [transport tcp | rdma | tcp,rdma] NEW-BRICK...
The default value for transport istcp
. Other options can be passed such asauth.allow
orauth.reject
. See Section 8.1, “Configuring Volume Options” for a full list of parameters.Example 6.1. Distributed Volume with Two Storage Servers
# gluster volume create test-volume server1:/exp1/brick server2:/exp2/brick Creation of test-volume has been successful Please start the volume to access data.
Example 6.2. Distributed Volume over InfiniBand with Four Servers
# gluster volume create test-volume transport rdma server1:/exp1/brick server2:/exp2/brick server3:/exp3/brick server4:/exp4/brick Creation of test-volume has been successful Please start the volume to access data.
- Run
# gluster volume start VOLNAME
to start the volume.# gluster volume start test-volume Starting test-volume has been successful
- Run
gluster volume info
command to optionally display the volume information.The following output is the result of Example 6.1, “Distributed Volume with Two Storage Servers”.# gluster volume info Volume Name: test-volume Type: Distribute Status: Created Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: server1:/exp1/brick Brick2: server2:/exp2/brick
