Publication number: 20240036968Abstract: Described herein are systems, methods, and software to manage configuration attempts for a service following a failure associated with the service according to an implementation. In one example, a management service monitors hosts in a computing environment and identifies a failure associated with a service on a first host. In response to identifying the failure, the management service identifies one or more criteria to initiate an attempt to configure the service based on the type of failure and initiates the attempt to configure the service when the one or more criteria are satisfied. Additional attempts can be initiated by the management service if the initial configuration attempt fails after a timeout interval.Type: ApplicationFiled: October 31, 2022Publication date: February 1, 2024Inventors: DIVYA TUMKUR PRAKASH, RAHUL KUMAR SINGH, ANIKET AVINASH SAKHARDANDE, ALKESH SHAH, NIHAL TIWARI

Publication number: 20230393882Abstract: Described herein are systems, methods, and software to manage virtual machine shutdowns in a computing environment. In one example, a management service identifies a virtual machine file in a file system associated with a first virtual machine and one or more additional virtual machines and identifies a lock on the virtual machine file by the first virtual machine. The management service further stops execution of the one or more additional virtual machines in response to identifying the lock.Type: ApplicationFiled: May 30, 2023Publication date: December 7, 2023Inventors: Avinash Nagalapur Jambana GOUD, Aniket Avinash Sakhardande, Alkesh Shah, Brian Masao OKI, Vasantha Kumari Tammana

Patent number: 11824929Abstract: The present disclosure relates to using maintenance mode to upgrade a distributed system. One method includes determining that a first host of a cluster of a software-defined datacenter (SDDC) is to be upgraded as a part of a rolling upgrade of the hosts of the cluster, wherein the first host is executing a process instance of a cluster store, demoting the process instance to a proxy, creating a replica of the process instance using a different proxy on a second host of the cluster, instructing the first host to enter a maintenance mode, upgrading the first host, and instructing the first host to leave the maintenance mode.Type: GrantFiled: July 25, 2022Date of Patent: November 21, 2023Assignee: VMware, Inc.Inventors: Alkesh Shah, Ramses V.

Publication number: 20230333758Abstract: A method for maintaining fault tolerance in a storage cluster is provided. Embodiments include receiving, by a management component associated with a distributed data store on a cluster of host machines, a request to place a first host machine of the cluster of host machines in a maintenance mode, wherein the first host machine stores given data of the distributed data store. Embodiments include determining whether a second host machine that does not currently store any data of the distributed data store exists in the cluster of host machines. Embodiments include determining, based on whether the second host machine exists in the cluster of host machines, whether to transfer the given data of the distributed data store from the first host machine to the second host machine. Embodiments include initiating the maintenance mode on the first host machine.Type: ApplicationFiled: June 20, 2023Publication date: October 19, 2023Inventors: Alkesh SHAH, Austin KRAMER, Leonid LIVSHIN, Ramses V.

Publication number: 20230118525Abstract: Examples described herein include systems and methods for backing up and recovering a software-defined data center (“SDDC”). In one example, entities of the SDDC, such as virtual machines, hosts, and clusters, can coexist with corresponding entity stores. The entity stores can store current state information for each SDDC entity. For example, an identifier or name of a virtual machine can be stored in that virtual machine's corresponding entity store. When recovery of a controller is needed, the controller can rebuild state information that has changed after the controller was backed up, by retrieving state information from entity stores of the various SDDC entities.Type: ApplicationFiled: December 19, 2022Publication date: April 20, 2023Inventors: Alkesh Shah, Maarten Wiggers, Cheng Cheng, Leonid Livshin, Konstantinos Roussos
