1. A method for data management in a storage grid, by a processor device, comprising:

  • directing data Input/Output (I/O) operations from a host to an owning node according to a Logical Block Address (LBA) without a static assignment of ownership, notwithstanding any relationship between the host and the storage grid;

    directing the I/O operations according to a mapper layer used to create a dynamic block device, wherein the dynamic block device maintains I/O routing configuration decisions;

    maintaining, by the block device, a Logical Address Block (LBA) map;

    pointing, by the LBA map, to the owning node holding a certain LBA; and

    populating the LBA map according to a storage distribution formula, the storage distribution formula containing a seed number of a Logical Unit Name (LUN).
