Gluster 3.1: Migrating a Disk

From GlusterDocumentation

<<Formatting a Disk | Table of Contents | Deleting a Server>>

You can migrate disks, that is, move data from one disk to another within your cluster. You might want to do this, for example, when upgrading a disk to another with a larger capacity.

When migrating a disk, the Management Console allows you to select both the source and destination server partitions. After initiating a disk migration, the Servers tab displays the status of the migration, and allows you to cancel the migration, if necessary.
