Abstract

Techniques for management of data storage in distributed storage systems are provided. A method may include receiving, by a computer system, a request to write data to a volume. The method may include identifying, by the computer system, a zone segment mapped to the volume. The zone segment may include a plurality of zones. The method may include identifying, by the computer system, a segment pointer indicating a write location in a zone of the zone segment. The method may include writing, by the computer system, the data to one or more zones of the plurality of zones of the zone segment, starting at the write location. The method may also include updating, by the computer system, the segment pointer according to a data endpoint of the data in the zone segment.

Claims20

Dependent claims

One or more non-transitory computer-readable media storing instructions that, when executed by one or more hardware processors, cause performance of operations comprising:

selecting a first zone segment for a defragmentation process, wherein the first zone segment comprises stored data that has been written to the first zone segment via a prior write operation, wherein a configuration associated with the first zone segment results in the stored data impeding any writing of additional data to unused storage capacity of the first zone segment via any new write operation while the stored data is maintained within one or more source zones of the first zone segment;
accessing the stored data comprised within the one or more source zones of the first zone segment;
writing, in a single write operation, the stored data to a plurality of target zones,
wherein the plurality of target zones comprises at least (a) a first zone and (b) a second zone that is subsequent to the first zone in the plurality of target zones;
and
resetting at least one of the one or more source zones of the first zone segment to an empty status or an open status.

3 more elements

A method, comprising:

selecting a first zone segment for a defragmentation process, wherein the first zone segment comprises stored data that has been written to the first zone segment via a prior write operation, wherein a configuration associated with the first zone segment results in the stored data impeding any writing of additional data to unused storage capacity of the first zone segment via any new write operation while the stored data is maintained within one or more source zones of the first zone segment;
accessing the stored data comprised within the one or more source zones of the first zone segment;
writing, in a single write operation, the stored data to a plurality of target zones,
wherein the plurality of target zones comprises at least (a) a first zone and (b) a second zone that is subsequent to the first zone in the plurality of target zones;
and
resetting at least one of the one or more source zones of the first zone segment to an empty status or an open status,
wherein the method is performed by at least one device including a hardware processor.

4 more elements

A system, comprising:

at least one device including a hardware processor;
and
the system being configured to perform operations comprising:
selecting a first zone segment for a defragmentation process, wherein the first zone segment comprises stored data that has been written to the first zone segment via a prior write operation, wherein a configuration associated with the first zone segment results in the stored data impeding any writing of additional data to unused storage capacity of the first zone segment via any new write operation while the stored data is maintained within one or more source zones of the first zone segment;
accessing the stored data comprised within the one or more source zones of the first zone segment;
writing, in a single write operation, the stored data to a plurality of target zones,
wherein the plurality of target zones comprises at least (a) a first zone and (b) a second zone that is subsequent to the first zone in the plurality of target zones;
and
resetting at least one of the one or more source zones of the first zone segment to an empty status or an open status.
