Abstract
A system includes a plurality of nodes, a first memory device including a plurality of volumes each visible to at least one of the plurality of nodes within a visibility configuration, and a processing device, operatively coupled with the plurality of nodes and the first memory device. The processing device performs operations including identifying a system failure affecting visibility of at least one of the plurality of volumes of the first memory device, and modifying the visibility configuration to address the system failure.
Claims20
A system comprising:
- a plurality of nodes;
- a first memory device comprising a plurality of volumes each visible to at least one of the plurality of nodes within a visibility configuration, each of the plurality of volumes comprising a persistent memory region (PMR) and a namespace;
- and
- a processing device, operatively coupled with the first memory device, to perform operations comprising:
- identifying a system failure affecting visibility, to at least one of the plurality of nodes, of at least one of the plurality of volumes of the first memory device;
- and
- modifying the visibility configuration to address the system failure.
A method comprising:
- identifying, by a processing device, a system failure affecting visibility of at least one of a plurality of volumes of a first memory device, wherein each of the plurality of volumes is visible to at least one of a plurality of nodes within a visibility configuration and comprises a persistent memory region (PMR) and a namespace;
- and
- modifying the visibility configuration to address the system failure.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- initializing a visibility configuration to enable visibility of each of a plurality of volumes of a first memory device to at least one of a plurality of nodes, wherein the plurality of volumes comprises a first volume and a second volume each comprising a persistent memory region (PMR) and a namespace, and wherein the plurality of nodes comprises a first node and a second node;
- and
- addressing a system failure affecting the visibility of at least one of the plurality of volumes of the first memory device by modifying the visibility configuration to obtain a modified visibility configuration.
