Remote volume clone

A method comprising:

• providing a storage pod having a group of disks containing a plurality of Redundant Array of Independent Disks (RAID) groups, wherein an entirety of a global physical volume block number (PVBN) space associated with the storage pod is visible and accessible to all nodes of a plurality of nodes of a cluster representing a distributed storage system;
• and
• creating, for use by a destination node of the plurality of nodes, a remote clone volume of a parent volume associated with a source node of the plurality of nodes by:
• creating a dummy volume on the destination node;
• converting the dummy volume into the remote clone volume by copying metadata associated with a backing snapshot of the parent volume to the dummy volume;
• and
• after completion of the remote clone volume, locking the backing snapshot.

A distributed storage system comprising:

• one or more processing resources;
• and
• instructions that when executed by the one or more processing resources cause the distributed storage system to:
• make use of a storage pod having a group of disks containing a plurality of Redundant Array of Independent Disks (RAID) groups, wherein an entirety of a global physical volume block number (PVBN) space associated with the storage pod is visible and accessible to all nodes of a plurality of nodes of a cluster representing a distributed storage system;
• and
• create, for use by a destination node of the plurality of nodes, a remote clone volume of a parent volume associated with a source node of the plurality of nodes by:
• creating a snapshot of the parent volume on the source node;
• locking the snapshot;
• creating a local clone volume of the parent volume on the source node;
• and
• converting the local clone volume into the remote clone volume by performing a zero-copy volume move of the local clone volume to the destination node.

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

• make use of a storage pod having a group of disks containing a plurality of Redundant Array of Independent Disks (RAID) groups, wherein an entirety of a global physical volume block number (PVBN) space associated with the storage pod is visible and accessible to all nodes of a plurality of nodes of a cluster representing a distributed storage system;
• and
• create, for use by a destination node of the plurality of nodes, a remote clone volume of a parent volume associated with a source node of the plurality of nodes by:
• creating a dummy volume on the destination node;
• converting the dummy volume into the remote clone volume by copying metadata associated with a backing snapshot of the parent volume to the dummy volume;
• and
• after completion of the remote clone volume, locking the backing snapshot.
