6.3. Creating Distributed Volumes
Figure 6.1. Illustration of a Distributed Volume
Create a Distributed Volume
gluster volume createcommand to create different types of volumes, and
gluster volume infocommand to verify successful volume creation.
- 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 createcommand to create the distributed volume.The syntax is
gluster volume create NEW-VOLNAME [transport tcp | rdma | tcp,rdma] NEW-BRICK...The default value for transport is
tcp. Other options can be passed such as
auth.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.
# gluster volume start VOLNAMEto start the volume.
# gluster volume start test-volume Starting test-volume has been successful
gluster volume infocommand 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
