Handling data extent size asymmetry during logical replication in a storage system

A computing device, comprising:

• a memory comprising machine executable code having stored thereon instructions;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• receive, by a first device from a second device, a first data block and a second data block having a first size that is a smallest size usable by a file system of the second device;
• store the first data block and the second data block into a single destination data block having a second size that is a smallest size usable by a file system of the first device;
• and
• maintain a mapping among a first source identifier of the first data block and a second source identifier of the second data block with the single destination data block.

A non-transitory computer-readable medium having stored thereon instructions which when executed by a machine, causes the machine to:

• receive, by a first device from a second device, a first data block and a second data block having a first size that is a smallest size usable by a file system of the second device;
• store the first data block and the second data block into a single destination data block having a second size that is a smallest size usable by a file system of the first device;
• and
• maintain a mapping among a first source identifier of the first data block and a second source identifier of the second data block with the single destination data block.
