US 11,354,160 B2 · Methods for managing storage quota assignment in a distributed system and devices thereof

Abstract

Methods, non-transitory machine readable media, and computing devices that more efficiently and effectively manage storage quota enforcement are disclosed. With this technology, a quota ticket comprising a tally generation number (TGN) and a local allowed usage amount (AUA) are obtained. The local AUA comprises a portion of a global AUA associated with a quota rule. The local AUA is increased following receipt of another portion of the global AUA in a response from a cluster peer, when another TGN in the response matches the TGN and the local AUA is insufficient to execute a received storage operation associated with the quota rule. The local AUA is decreased by an amount corresponding to, and following execution of, the storage operation, when the increased local AUA is sufficient to execute the storage operation.

Dependent claims

A method, comprising:

obtaining, by a first cluster peer, from a second cluster peer designated as a tally manager, a quota ticket comprising a tally generation number (TGN) and a local allowed usage amount (AUA) that comprises a portion of a global AUA associated with a quota rule;
sending, by the first cluster peer, a steal request to a third cluster peer when the local AUA of the first cluster peer is insufficient to execute a received storage operation associated with the quota rule;
increasing, by the first cluster peer, the local AUA following receipt of another portion of the global AUA in a response to the steal request from the third cluster peer, when another TGN in the response to the steal request matches the TGN in the quota ticket;
executing, by the first cluster peer, the storage operation, when the increased local AUA is sufficient to execute the storage operation;
and
decreasing, by the first cluster peer, the local AUA by an amount corresponding to the storage operation following the execution of the storage operation.

3 more elements

A non-transitory machine readable medium having stored thereon instructions for storage quota enforcement comprising machine executable code which when executed by at least one machine causes the machine to:

obtain, from a first cluster peer designated as a tally manager, a quota ticket comprising a tally generation number (TGN) and a local allowed usage amount (AUA) that comprises a portion of a global AUA associated with a quota rule;
send a steal request to a second cluster peer when the local AUA is insufficient to execute a received storage operation associated with the quota rule;
increase the local AUA following receipt of another portion of the global AUA in a response to the steal request from the second cluster peer, when another TGN in the response to the steal request matches the TGN in the quota ticket;
execute the storage operation, when the increased local AUA is sufficient to execute the storage operation;
and
decrease the local AUA by an amount corresponding to the storage operation following the execution of the storage operation.

3 more elements

A first cluster peer, comprising:

a memory containing machine readable medium comprising machine executable code having stored thereon instructions for storage quota enforcement;
and
a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
obtain, from a second cluster peer designated as a tally manager, a quota ticket comprising a tally generation number (TGN) and a local allowed usage amount (AUA) that comprises a portion of a global AUA associated with a quota rule;
send a steal request to a third cluster peer when the local AUA of the first cluster peer is insufficient to execute a received storage operation associated with the quota rule;
increase the local AUA following receipt of another portion of the global AUA in a response to the steal request from the third cluster peer, when another TGN in the response to the steal request matches the TGN in the quota ticket;
execute the storage operation, when the increased local AUA is sufficient to execute the storage operation;
and
decrease the local AUA by an amount corresponding to the storage operation following the execution of the storage operation.
