Methods and systems of managing a distributed replica based storage

A computer tangible non-transitory readable medium comprising computer executable logic enabling execution across one or more processors of:

• mapping a plurality of replica sets to a plurality of storage managing modules installed in a plurality of computing units, each of the plurality of storage managing modules manages access of at least one storage consumer application to replica data of at least one replica of a replica set from the plurality of replica sets, the replica data is stored in at least one drive of a respective the computing unit;
• wherein the mapping maps blocks of volumes to a respective block address in a respective domain;
• allocating at least one time based credit to at least one of each storage managing module, the at least one drive and the replica data;
• iteratively renewing the time based credit as long a failure of at least one of the storage managing module, the at least one drive and the replica data is not detected;
• and
• for a storage managing module that does not have a renewed credit, fencing the storage managing module by sending a declaration of failing to the other of the plurality of storage managing modules;
• wherein a fenced storage managing module stops servicing requests;
• reallocating the replica data to at least one other of the plurality of storage managing modules when the at least one time based credit is not renewed;
• wherein reallocating the replica data allows the replica data to be to be managed by other storage managing modules.

A system of managing a distributed storage space, comprising;

• mapping a plurality of storage managing modules installed in a plurality of computing units and manages the storage of a plurality of replica sets, each storage managing module manages access of at least one storage consumer application to replica data of at least one replica of a replica set from the plurality of replica sets, the replica data is stored in at least one drive of a respective the computing unit;
• wherein the mapping maps blocks of volumes to a respective block address in a respective domain;
• and
• a central node which allocates at least one time based credit to at least one of each storage managing module and the replica data;
• wherein the central node iteratively renews the time based credit as long a failure of at least one of the storage managing module, the at least one drive and the replica data is not detected;
• and
• for a storage managing module that does not have a renewed credit, fencing the storage managing module by sending a declaration of failing to the other of the plurality of storage managing modules;
• wherein a fenced storage managing module stops servicing requests;
• further comprising, reallocating the replica data to at least one other of the plurality of storage managing modules when the at least one time based credit is not renewed;
• wherein reallocating the replica data allows the replica data to be to be managed by other storage managing modules;
• wherein the mapping maps blocks of volumes to a respective block address in a respective domain;
• reallocating the replica data to at least one other of the plurality of storage managing modules when the at least one time based credit is not renewed:
• wherein reallocating the replica data allows the replica data to be to be managed by other storage managing modules.
