Migrating data using volume clones in a distibuted storage system

A non-transitory, machine-readable medium storing instructions, which when executed by one or more processing resources of a computing system, cause the computing system to:

• clone a multiple-logical unit number (LUN) volume into a plurality of cloned single-LUN volumes on a first storage node of the computing system;
• create a plurality of new volumes on a second storage node of the computing system based at least in part on the plurality of cloned single-LUN volumes;
• selectively copy snapshot data from the plurality of cloned single-LUN volumes to the plurality of new volumes;
• establish snapshot mirror relationships between the plurality of cloned single-LUN volumes and the plurality of new volumes;
• synchronize the plurality of cloned single-LUN volumes and the plurality of new volumes;
• and
• perform a migration of data logical interface failovers (LIFs) from the plurality of cloned single-LUN volumes to the plurality of new volumes.

A computing system comprising:

• one or more processing resources;
• and
• instructions that when executed by the one or more processing resources cause the computing system to:
• clone a multiple-logical unit number (LUN) volume into a plurality of cloned single-LUN volumes on a first storage node of the computing system;
• create a plurality of new volumes on a second storage node of the computing system based at least in part on the plurality of cloned single-LUN volumes;
• selectively copy snapshot data from the plurality of cloned single-LUN volumes to the plurality of new volumes;
• establish snapshot mirror relationships between the plurality of cloned single-LUN volumes and the plurality of new volumes;
• synchronize the plurality of cloned single-LUN volumes and the plurality of new volumes;
• and
• perform a migration of data logical interface failovers (LIFs) from the plurality of cloned single-LUN volumes to the plurality of new volumes.
