1. A method comprising:
in response to determining that a primary volume hosted by a primary node has experienced a failure, creating a secondary node on-demand in response to the failure;
generating an on-demand volume accessible to the secondary node, wherein a restore process is initiated to restore the on-demand volume to a state of the primary volume captured by a snapshot stored within an object store; and
in response to copying metadata in the snapshot to the secondary node, providing clients with read and write access to the on-demand volume through the secondary node during the restore process.
