  • Patent number: 11599418
    Abstract: Methods, systems and computer program products for maintaining components of networked nodes with distributed data dependencies are described. For example, in accordance with one or more embodiments, a method can comprise identifying, by a device comprising a processor, in a group of dependent nodes of a cluster of nodes, a first portion of the dependent nodes for which an update is implicated. The method can further comprise selecting, by the device, from the first portion, a second portion of the dependent nodes that are predicted to be able to be updated with the update without affecting access to data of the group of dependent nodes. Further, the method can comprise communicating, by the device, the update to the second portion of the dependent nodes.

  • Patent number: 11579864
    Abstract: Accelerated behavior change for upgrades in a distributed system is described herein. A method as described herein can include facilitating a file system upgrade of a first computing node of a computing cluster from a first file system version to a second file system version that is newer than the first file system version, wherein the file system upgrade comprises pre-restart operations and a system restart performed subsequent to the pre-restart operations; activating a supervisor system of the first computing node in response to the first computing node completing the file system upgrade; and causing, in response to the activating, the supervisor system of the first computing node to initiate concurrent performance of the pre-restart operations of the file system upgrade at second computing nodes of the computing cluster, distinct from the first computing node.

  • Patent number: 11429593
    Abstract: Sharing a state between network computing devices is described. For instance, a first state update can be received from a second computing device via a network connection. Further, in a shared state file stored in a storage device coupled to the first computing device, a first portion of the shared state file is identified that is allocated to the second computing device. Further, based on the first state update, the first portion of the shared state file can be updated.

  • Patent number: 11349959
    Abstract: Delayed node upgrade in distributed systems is described herein. A method as described herein can include halting first client disconnections associated with a reboot operation of a file system update at a first computing node of a computing cluster in response to the first computing node being added to a delay list; causing, in further response to the first computing node being added to the delay list, second client disconnections associated with the reboot operation of the file system update at a second computing node of a group of second computing nodes of the computing cluster that are distinct from the first computing node; clearing, in response to the file system update being completed at respective ones of the group of second computing nodes, the delay list; and restarting, in response to clearing the delay list, the first client disconnections at the first computing node.
