Create a Distributed Striped Replicated Volume
gluster volume createto create a distributed striped replicated volume, and
gluster volume infoto 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 striped replicated volume.The syntax is
# gluster volume create NEW-VOLNAME [stripe COUNT] [replica COUNT] [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 6.12. Distributed Replicated Striped Volume Across Four ServersThe order in which bricks are specified determines how bricks are mirrored with each other. For example, first n bricks, where n is the replica count. In this scenario, the first two bricks specified mirror each other. If more bricks were specified, the next two bricks in sequence would mirror each other.
# gluster volume create test-volume stripe 2 replica 2 transport tcp server1:/exp1/brick server1:/exp2/brick server2:/exp3/brick server2:/exp4/brick server3:/exp5/brick server3:/exp6/brick server4:/exp7/brick server4:/exp8/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
